Cell Theory Cell Theory is a way to describe the biology of living things. Cell theory says that the cell is the basic unit of life. Cells by themselves are alive, but they can also be part of a larger living thing. The smallest living organisms (like bacteria but not viruses) and the biggest ones (like humans and whales) are all made of cells. Very small organisms like bacteria and amoebas are only made of one cell each, so they are called unicellular organisms ("uni" means "one"). Larger organisms

Unit 2 the muscular system The muscular system is responsible for the movement of the human body. Attached to the bones of the skeletal system are about 700 named muscles and takes up half of a person’s body weight .Each of these muscles is an organ constructed of skeletal muscle tissue, blood vessels, tendons, and nerves. Muscle tissue is also found inside of the heart, digestive organs, and blood vessels. Humans have three types of muscle skeletal, cardiac and smooth muscles. Muscle types

Are steroids the way to go? What comes to mind, when you vision an extremely broad man with bulging muscles. Steroids are an easier way to get stronger, it helps build muscles promptly. This makes getting muscles quicker and not having to put in much effort. Steroid use can cause huge muscles, but could have awful health effects in the long. Some effects are heart failure and liver cancer. Finally, how steroids were used then and how they are used now. There are positives and negatives to using

These drugs function by inhibiting acetylcholinesterase (an enzyme that breaks down acetylcholine) in order to increase both the duration and level of acetylcholine action, thus increasing neuromuscular transmission and assisting in muscular contraction. Pyridostigmine competes with acetylcholine for attachment to acetylcholinesterase in order to slow down acetylcholine hydrolysis. On the other hand, neostigmine blocks the active site of acetylcholinesterase, preventing acetylcholinesterase

Tractions When a person has a fracture, there is many process that he or she has to go through. An major process in which it helps with the healing of an fracture involves tractions. Traction is a technique in which it uses weight to pull the muscle or skeleton. It requires the pull of the client's natural force and the forces of the weights. By having the two forces pull, it aligns the muscle and the skeleton. It is use for clients who have a fracture, muscle spasm and keep alignment

P3 Identify the location of the major muscles in the human body Muscular system: Bicep brachii In human anatomy, the biceps brachii generally known as the biceps, is a two-headed muscle that lies on the upper arm between the shoulder and the elbow. Both heads arise on the scapula and join to form a single muscle surface which is attached to the upper forearm. Triceps brachii The triceps brachii muscle is the large muscle on the back of the arm. It is the muscle mainly responsible for extension of

Some tissues that are in this chapter are nervous tissue, muscular tissue, connective tissue and bone tissue . Nerve tissue is the way the organs of the nervous system, which consists of the bodies of nerve cells (neurons) and its extensions, and the glia. This tissue consists of cells called neurons very specialized and glial cells that support and nutrition to the above. Nerve cells or neurons: By stars and with many extensions. Are specialized to transmit nerve impulses. They are the only cells
