1. There is an inverse relationship between the total magnification and the diameter of the field of view. As magnification increases, the field of view decreases as seen in the calculations. 2. About 1 micrometer as seen from the drawing of the bacteria and averaging their sizes 3. 143 micrometers as seen from the drawings of the eukaryotes and averaging them. Eukaryotic cells are not all the same size as seen by comparing the size of the cheek cell to the size of a fungi cell. This can also be observed in just the cells of the different kingdoms of eukaryotes: protists, fungi, plants, and animals. 4. As seen in the elodea cell it is possible to see the cell wall, chloroplasts, central vacuole, and nucleus in plant cells as well as the plasma membrane, nucleus, and cytoplasm within animal cells. 5. In all of the cells it was possible to see a plasma membrane (clearly observed in the bacteria) that surrounds all cells and provides a barrier between the inside of the cell and the environment, cytoplasm that surrounds the chemicals and structures of a cell (example paramecium), as well as the small size of cells so the surface area and volume are proportional to each other to help maximize the efficiency of the cells. 6. In eukaryotic cell there is a nucleus present versus only the presence of genetic material in prokaryotic cells (example in cheek cell). Eukaryotic cells also have membrane bound organelles which allow compartmentalization within cells allowing eukaryotic cells to specialize (example seen in the elodea cells). Eukaryotic cells much larger than the size of prokaryotic cells (bacteria versus paramecium). 7. On a cellular level, the trend toward complexity is observed in the direction of increasing specialization. Starting with some of the most basic units of life seen in the bacteria cells there is only the cell membrane and

Reflection on Intro to Physiology/Anatomy

...We started with the introduction to anatomy by defining it as the scientific discipline that investigates the structure of the body. I have discovered that there are two basic approaches to the study of anatomy are systematic (by system) and regional (by area), the latter which is more commonly used in most medical schools. And of course studying the structure is not enough, this is where physiology comes in which is the scientific discipline that deals with the processes or functions of living things. I have known homeostasis as the maintenance of the relatively constant environment in the body but it is only now that I have learned about positive and negative feedback mechanisms which maintain homeostasis and that positive homeostasis can be detrimental at times. I’ve also learned more on the anatomical terms that will be used throughout our course and maybe even in med school. In the study of cells, I was able to recall the things we have discussed in our biological science course in the previous year. I remember the three types of solution namely hypotonic, isotonic, and hypertonic. I also come to know more about the different movements across the cell membrane. However I was new to the transcription and translation that happens in the gene expression of a cell. I was able to associate codons of the mRNA strand with the anticodon of the tRNA. Similar to cytology, I was also able to look back on our discussions about tissues last year. I have refreshed myself on the...

Form and Function in Biology

...Cuvier, the ‘father of comparative anatomy’ laid out in his theory of ‘the correlation of parts’ that similarly appearing anatomical structures should have similar functions and this similarity should be used to group or diagnose organisms and their structures (1). Further exploration of four examples in this paper will more clearly show that the function of any ‘thing’ is related directly to the form of its construction. To exemplify this connection between form and function let’s look at the construction of the largest organ of the body, specifically the layers of tissues found in the Skin or Integumentary System, as it’s known in scientific terminology. Constructed of two major layers (Epidermis and Dermis) the skin contains several types of epithelial and connective tissues. From a very cursory examination it’s clear that the skin is a durable, flexible and strong substance. Go a bit deeper and examine these layers for a more in depth evaluation of their form and the layers of the Epidermis and Dermis clearly declare their function from their form. The Dermis, constructed of a layer of connective tissue in the Reticular Layer, underneath the Papillary layer filled with capillary networks of blood vessels feeding the Epidermis up above. The Epidermis then is comprised of multiple layers of cells comprising four or five layers made up of Stratified Squamous Epithelial tissue whose form allows for constant re-growth of new Keratinized cells ready to replace those rubbed off...

These three men are always mentioned when the subject of who are the Great Greek men of the past who made a significant impact on the world. Hippocrates is another great Greek genius who made a significant impact not on Philosophy but on the field of Medicine. He is considered one of the most influential figures in the History of Medicine. He is referred to as the “Father of Medicine” because of his endless contributions to the medical field as the founder of the Hippocratic School of Medicine. He created a school which revolutionized medicine in Greece because this school would eventually establish medicine as a separate profession. He changed the perception of Greek medicine with his revolutionary vision that disease was not caused by gods or spirits but was the result of natural action. The life of Hippocrates will be discussed in further detail such as his early childhood & life, his work, and his contributions/accomplishments to the World until his death. Hippocrates was an ancient Greek physician, who is also called the "Father of Medicine". He was born on the Aegean island of Cos which is near the island of Greece called Halicarnassus during the Classical Greece era towards the end of the fifth century B.C.E, around 460 BC. Ancient Greek history also believed that he was related to Hercules through his...

The 7 Organizational Approaches

...The Seven Organizational Approaches Katrinda Allen HCA/220 4/26/13 Yelena Crater The seven organizational approaches are what we recognize to be the different parts of the body in laymen’s terms. In medical terms it would be recognized as body planes and body directions, body cavities, quadrants and regions, anatomy and physiology, microscopic to macroscopic, systems and medical specialties. These are all terms that we will access that describe the anatomy of the human body in depth. Body parts are the different parts of the body that we all use from day to day. Planes are imaginary flat surfaces that divide the body into separate parts. There are three main parts to the body when it is in the plane (anatomical view) sagittal plane which is the plane that divides the body into a left and right side view. Then there is the coronal view and the with this plane the body is divided into anterior and posterior view (front and back). We then have the transverse plane which is the horizontal plane and this plane is parallel to the ground and divides the body into up and down. And last we have the oblique plane which is a slanted plane that lies between the horizontal and vertical planes. We then look at the term body cavity which is the areas in the body that contain out internal organs. There are two main cavities of the human body and they are the dorsal and ventral cavities. The dorsal cavity is what is on the posterior (back) of the body and there are different cavities...

Creation vs Evolution

...about from a big bang • Creatures are ever evolving beings • Man evolved from an ape Creationism • A higher being, (God) created all life forms • Mankind was made in the image of God • God sustains all life forms. From the time I was in kindergarten I have always heard compelling arguments about the pros and cons of each belief but it was not until I took a class in Human Anatomy and Physiology, (A&P) that I was truly able to confirm that we are complex creatures made and sustained by a higher being. When one considers how organs work in perfect harmony with each other, maintaining a state of equilibrium, it is mind boggling. I will attempt to portray why I believe the theory of Creationism makes more sense than the theory of Evolution. One of the many studies I embraced in my A&P class was the contraction of a muscle. Sounds like a simple, non-complex activity right? That is until you find out what actions have to take place in order for a contraction to take place. The first activity that has to take place in order for a muscle to contract is an exchange of cellular fluid in the cell itself and the surrounding fluid which is known as cytoplasm. This exchange of Sodium and Potassium creates what is known as an Action Potential. Enzymes are then released from the axons where they would innervate with motor neurons causing the Sarcoplasmic Reticulum to release calcium into the blood stream. If the enzymes are released in...

Anatomy

...Anatomy is the branch of biology concerned with the study of the structure of animals and their parts; it is also referred to as zootomy to separate it from human anatomy. In some of its facets, anatomy is related to embryology and comparative anatomy, which itself is closely related to evolutionary biology and phylogeny.[1] Human anatomy is one of the basic essential sciences of medicine. The discipline of anatomy is divided into macroscopic and microscopic anatomy. Macroscopic anatomy, or gross anatomy, is the examination of an animal’s body parts using unaided eyesight. Gross anatomy also includes the branch of superficial anatomy. Microscopic anatomy involves the use of optical instruments in the study of the tissues of various structures, known as histology and also in the study of cells. The history of anatomy is characterized by a progressive understanding of the functions of the organs and structures of the human body. Methods have also improved dramatically, advancing from the examination of animals by dissection of carcases and cadavers (corpses) to 20th century medical imaging techniques including X-ray, ultrasound, and magnetic resonance imaging.

Seven Approaches

...healthy human body can be done in several different ways. Each way approaches the body from a specific standpoint and provides unique information about the body. Each approach divides and organizes complex information about the body in a logical way. These approaches include the following: body planes and body directions, body cavities, quadrants and regions, anatomy and physiology, microscopic to macroscopic, body systems, and medical specialties” (Turley, 2011). Body planes and body direction is one approach that divides the body into front and back, right and left, and top and bottom. The three main body planes are coronal, sagittal plane, and transvers plane. The body directions showcase the movement towards or away from the planes. The major directions are superior, inferior, anterior, posterior, medial, lateral, proximal, distal, superficial, and deep. “There are many times in medicine that a doctor has to record information in a medical record or tell another doctor the exact body part or location of disorders or damage to your body or an organ. To do that, there are standard terms for describing human anatomy including the body and its organs. These terms are often used to describe medical imaging such as CAT scans, PET scans and MRIs where the scans take pictures of the body in flat slices” (Media Partners, 2011). Body cavities are spaces that help protect and support organs. There are five major cavities of the body which are the cranial, spinal, thoracic, abdominal...

Organizational Change Paper

...Seven Organizational Approaches Paper HCA/220 January 29, 2012 Seven Organizational Approaches Paper The seven organizational approaches to studying the human body include: body plans and directions, body cavities, quadrants and regions, anatomy and physiology, microscopic-to-macroscopic, body systems, and medical specialty. The body planes and directions approach is the division of the body into sections from front to back, right and left, top and bottom, along with the movement toward or away from the body planes. The Coronal Plane or frontal plane is a vertical plane that divides the body into front and back sections. The front of the body is known as the anterior or ventral section and the back of the body is known as the posterior or dorsal section. The Sagittal Plane is a vertical plane that divides the body into right and left sections. The body directions represent the movement toward or away from the midline. Moving from the side of the body toward the midline is moving in a medial direction. Moving from the midline toward the side of the body is moving in a lateral direction. These types of approaches may be used to take images from a magnetic resonance imaging (MRI) scan. The Transverse Plane is a horizontal plane that divides the body into top and bottom sections. The superior is the upper half of the body and the inferior is the lower half. Moving from the trunk of the body toward the end of a body limb is moving in a distal direction. Moving...

...Clinical Notes The Visible Human Project p. 7 Homeostasis and Disease p. 13 An Introduction to Studying the Human Body This textbook will serve as an introduction to the inner workings of your body, providing information about both its structure and its function. Many of the students who use this book are preparing for careers in health-related fields—but regardless of your career choice, you will find the information within these pages relevant to your future. You do, after all, live in a human body! Being human, you most likely have a seemingly insatiable curiosity—and few subjects arouse so much curiosity as our own bodies. The study of anatomy and physiology will provide answers to many questions regarding the functioning of your body in both health and disease. Although we will be focusing on the human body, the principles we will learn apply to other living things as well. Our world contains an enormous diversity of living organisms that vary widely in appearance and lifestyle. One aim of biology—the science of life—is to discover the unity and the patterns that underlie this diversity, and thereby shed light on what we have in common with other living things. Animals can be classified according to their shared characteristics, and birds, fish, and humans are members of a group called the vertebrates, characterized by a segmented vertebral column. The shared characteristics and organizational patterns provide useful clues about how these animals have evolved over time...
