...continue to require replacement of some or all of their teeth. Surgical improvement of the denture-bearing area and surrounding tissue (preprosthetic surgery) offers an exciting and demanding challenge to the dental practice. Many minor modifications of the alveolar ridge and vestibular areas can greatly improve denture stability and retention. In some cases, patients have severe bone changes or soft tissue abnormalities that require extensive surgical preparation before the prosthetic appliance can be properly constructed and worn. Procedures that improve prosthesis retention and stability are discussed and illustrated in Chapter 13. One of the most exciting frontiers in dentistry is implantology. Proper bony and soft tissue reconstruction followed by placement of implants and subsequent prosthetic reconstruction can provide patients with a more natural and efficient substitution for their lost dentition. Depending on the circumstances, several types of implant systems may be used. Chapter 14 discusses the various types of implant systems currently in use and their advantages, disadvantages, and indications for use. 247 Preprosthetic Surgery Mark W. Ochs and Myron R.

...1.1. Explain the structure and composition of bone tissue Articular cartilage, also known as Hyaline cartilage, lays on the surface of a bone. The articular cartilage is typically depicted in four zones; the superficial zone, the transitional zone, the radial zone, and the calcified zone (James and Uhl, 2001, pp.414). Each zone, within the articular cartilage, has an important role in supporting movement and reducing friction. Supporting this, Barber (2007, pp.742) states that damage to any of these zones would result in progressive deterioration, and alterations to the normal biomechanical properties within the articular cartilage. This suggests that any damage to the articular cartilage will result in deterioration of bone and reduction...

...THE ADVERSE INFLUENCE OF PORK CONSUMPTION ON HEALTH by Professor Hans-Heinrich Reckeweg, M.D. Biological Therapy Vol.1 No. 2 1983 In consideration of wide sections of the population, it appeared strongly advisable to investigate more closely the reasons for the nocuity of pork and to report on the toxic and stress factors contained in pork, i.e. sutoxins. A possibility emerges that everyone can stay healthy by omitting toxic factors (specific pork poisons) from his diet or can regain health by observing a strict ban on pork. The fact that pork causes stress and gives rise to poisoning is known. It is obvious that this does not only apply to preparations of fresh pork such as cold cuts, knuckles, feet, ribs and cutlets, etc., but also to cured meats (ham, bacon, etc.) and to smoked meats prepared for sausages. Consumption of freshly killed pork products causes acute responses, such as inflammations of the appendix and gall bladder, biliary colics, acute intestinal catarrh, gastroenteritis with typhoid and paratyphoid symptoms, as well as acute eczema, carbuncles, sudoriparous abscesses, and others. These symptoms can be observed after consuming sausage meats (including salami which contains pieces of bacon in the form of fat). The consumption of pork is particularly dangerous in the tropical regions. This, for example, is shown in parts of Africa where both the Islamic and Western civilizations live in neighboring territories under the same climatic conditions. The same conditions...

...triglycerides, phospholipids, and sterols (cholesterol). Triglycerides are fatty acids. Its functions include energy storage and the cushioning and insulating of the body and nerves. All nerves are wrapped in a myelin sheath; or lipid layer. Phospholipids are similar to triglycerides, but contain a phosphate group. It is a lipid bilayer – membranes in eukaryotic cells and the plasma membrane of cells. Sterols are made from lipids, but have no fatty acids in their structure. Cholesterol makes up sex hormones and carries lip-proteins. Describe briefly what is occurring at each step in the figure.

...Describe the following tissue types: Epithelial - Epithelial tissue covers the entire surface of the body. It is made up of cells nearly pressed and extended in one or more layers. This tissue is specific to structure the covering or coating of all inward and outer body surfaces. Epithelial tissue that happens on surfaces on the inside of the body is known as endothelium. Epithelial cells are packed firmly together, with practically no intercellular spaces and just a little measure of intercellular substance. Epithelial tissue is generally divided from the underlying tissue by a meagre sheet of connective tissue; cellar layer. The basement membrane gives structural backing to the epithelium furthermore ties it to neighbouring structures. Epithelial tissue can be divided into two groups depending on the number of layers of which it is creates. Epithelial tissue which is stand out cell thick is known as basic epithelium. On the off chance that it is two or more cells thick, for example, the skin, it is known as stratified epithelium. There are also nerve supplies to the epithelia but they are supplied with oxygen and nutrients from deeper tissues by diffusion. There are three types of epithelial tissue, which include cuboidal, columnar and squamous Simple cuboidal epithelia are a type of epithelium that refers to a single layer of cube-like cells. These cuboidal cells have large, spherical and central nuclei. The cells of this sort of tissue can withstand more trauma than basic...

...The effects of ultrasound waves on biological tissues are called bioeffects. Ultrasound is a non-ionizing form of radiation, they have an extremely low frequency which is why ultrasound waves are not known to cause harm to human tissue. There are different categories of bioeffects; these categories are known as thermal effects and mechanical effects. Thermal bioeffects depend on the duration of exposure and the frequency. In brightness modulation and in color mode a wider area is scanned so the heat can be distributed over that space. In amplitude modulation, motion mode, and Doppler modes, one line is scanned repeatedly to gather information which in turn makes that line have a concentrated amount of heat, increasing the likelihood of thermal bioeffects occurring. Thermal Index (TI) is the on screen measurement of the amount of energy absorbed by the body over a certain period of time. Thermal bioeffects are used as a form of medical heat therapy sometimes by applying low frequency ultrasound to joint and muscle sprains or tendonitis. Also thermal bioeffects have been used to thermally kill tumors or stop bleeding. Mechanical bioeffects are the effects of the ultrasound wave that are non-thermal, produced by force. The force that is usually produced is something called cavitation. Cavitation can occur if the Mechanical Index (MI) is the measure on screen of the potential for cavitation to begin in the tissue. There are two types of cavitation; stable cavitation that the gas bubbles...

...Lesson 1: A & P of Skin and Soft Tissue Answers/Rationale 1. F The pH of normal, healthy skin is slightly acid, not alkaline. 2. F Dermis, is the inner most layer of skin that is naturally moist and slightly acid. 3. T Epidermis is the outer layer of skin, composed of stratified squamous epithelial cells,which can reproduce/regenerate to replace lost cells. 4. F Subcutaneous tissue is not a layer of skin. Only the epidermis and dermis comprise the skin. Subcutaneous tissue is fatty tissue/adipose tissue underneath the skin that provides padding and protection. 5. T Tissues need intermittent blood flow. Compression of tissue between a bone and external surface/ cast/splint or device, compresses blood vesslels and can cut off the blood flow to tissue resulting in ischemia that causes tissue damage and if prolonged, ulceration. 6. T Muscle tissue is highly vascular with a higher metabolic rate and therefore is more susceptible than skin to effects of prolonged pressure. Muscle is also not capable of reproduction/regeneration. 7. F Maceration stretches cells in the skin increasing the risk of damage. 8. Rete pegs and rete ridges are epidermal protrusiuons that project down into the dermis to interlock with the dermal papillae to provide strength and stability of the skin layers and prevent skin tears. Without the interlocking of the epidermis to the dermis, or if there is flattening of this junction, the epidermis can easily be torn away from the dermis. The rete pegs and ridges are...

...Cayenne Pepper for Lucious, Thick Lips Yeah, I know... it sounds weird, however, using cayenne pepper for luscious, thick lips is not as odd as one would think. It's much safer than the Kylie Jenner Challenge. Have you seen or heard about it? It's where you take a small container like a shot glass and cover your lips and suck. Sucking in the air creates friction and when you remove the glass, your lips are bigger. Sometimes, they are much bigger than anticipated. LOL Really, it's no laughing matter as this practice comes with a warning. The glass could break and could cause injury. Still, you could get injections but who's got time or money for that. Or you can stick with the natural resources that you already have around the house. If you are sensitive to hot, spicy foods then this may not be for you. However, I love spicy, so I had to try it and the results are in... I'll do it again! LOL Fortunately, I was born with a set of full lips, but sometimes, I want to add a little ump and mystic to my appearance. It's unfortunate that not everyone was blessed with plump lips, but we can remedy that situation in a couple of ways and I'll tell you how. Owning a Pair of Full Lips 1.) Getting a set of full lips is easy. All you have to do is add a little ground cayenne pepper to your lip gloss or to a small container of Vaseline and apply as you would ordinarily. The purpose of the cayenne is to swell the lips and it does so safely and quickly. You may feel a little...

...1.1 Describe the four basic human body structure units and their functions The way in which physical processes and functions take place in the body can be looked at on four main levels, moving progressively from the detailed to the general. At the most detailed level are the cells – the most basic of the physical structure units. Similar cells, when combined and held together, form tissue, the next main structure unit. Organs are collections of tissues that are combined to perform a particular function in the body. Organs do not work in isolation, however, and combine with other organs to create a biological system. Cells The cell is the most basic structural unit in the body. There are around 300 different cell types in the human body. While they differ in function, there are certain fundamental components or features that they generally have in common, such as a nucleus (with the exception of red blood cells), cytoplasm and a cell or plasma membrane. A cell membrane is composed of 60% protein, and 40% lipid, or fat. This membrane is a phospholipid bilayer which contains embedded protein molecules. It is a living boundary separating the living contents of the cell from its environment. Its function is to regulate the passage of molecules into and out of the cell. Within the membrane, the cell consists of cytoplasm, a gel-like substance containing organelles - small structures each with their own function. Common to all human cells except red blood cells, the nucleus is...

...The Secret Lives of Cells The author here, Laura Wright, has written an article review of the book, “The Immortal Cells of Henrietta Lacks.” In her review, it is easy to discern that the author understands aspects of research but she definitely questions the ethics of the researchers involved. This is evident in the descriptive used for the researchers when she says, “Skloot’s telling of this aspect of modern medicine reads like good fiction, rich with characters of mixed stripes: insensitive jerks, ignorant brainiacs; some blindly altruistic to the point of naïveté, others who fully understood that they were deceiving patients about the true value of their cast-off tissues.” (Wright, 2010). The author closes her review with “As we hurtle toward the day when a visit to the doctor begins with a thorough DNA exam, the question of what exactly we’ll leave for the taking when we exit remains wide open.” (Wright, 2010). These comments are indicators of the author’s viewpoint on the matter. I always find myself with ambivalent feelings and viewpoints in terms of the science of medicine and how discovery and advances are made, especially when there are people of color involved. Historically, African Americans have been the “guinea pig” group for all types of trials and testing. I believe this stems from early societal structure and the determination to prove that African Americans were the most inferior group of human beings. I also believe in research and the science of...

... Health and Social Care The structure of the main tissues of the body- P2 A humans body is made up entirely of cells, without cells there would be no body. Tissues are basically groups of cells, that have almost the shape and function, and there are four main tissues of the body, which are: Epithelial tissue, Connective tissue, Nervous tissue and Muscle tissue. Epithelial tissue- Epithelial tissue is one of the most important tissues of the body as it covers all of the surface of the human body. This tissue is made up of cells which are all packed in one or multiple layers. The main job of this tissue is to form the covering or lining of all of the internal and external bodies surfaces. Epithelial cells are packed tightly together, with almost spaces between them, and only a small amount of inter cellular substance. Inter celluar substance is the bodies substance in which tissue cells are embedded. No matter what the type is, Epithelial tissue is usually separated from the underlying tissue by a thin sheet of connective tissue, this is called basement membrane. The basement membrane's job is to provide structural support for the epithelium and also to bind it to neighboring structures. Connective tissue- The main role of connective tissue is to fill in the spaces between organs and tissues, and also to provide structural and metabolic support for other tissues and organs. Connective tissue is made up of cells and extra cellular matrix. The extra cellular matrix...

...response to particulate matter exposures. Epithelial Barrier Epithelial barrier is the unique body mechanism supporting transportation of different chemical substances including nutrients and water into the cells and tissues (Sharma & Tepas, 2010). In addition, it has very important role in prevention of microbial contamination. People with pathologies of epithelial barrier are vulnerable to numerous diseases. Epithelial barrier takes part in translocation of particulate matter in the human body. This translocation occurs when particulate matter deposited in the lungs interacts with epithelial cells (Gurjar, Molina & Ojha, 2010). Translocation of particulate matter through epithelial barrier is performed with the help of inter-epithelial transport leading or dendritic cells. Epithelial barrier is susceptible to the influence of particulate matter. As a result of exposures to particulate matter of various degrees and doses, epithelial barrier in different tissues may lose its functionality partially or completely. Endothelial Barrier Endothelial barrier is the vessel barrier made of endothelial cells, which covers the inner surface of lymphatic vessels and blood vessels with the purpose of hindering the entrance of leukocytes and blood fluid into tissue (Sharma & Tepas, 2010). Endothelial barrier functions in combination with the basement membrane. Such formation of the inner...
