The CNS contains immune cells called the microglial cells. The microglial cells destroy foreign bodies, nervous tissue, which is dead and the microorganisms by phagocytosis and are found in the brain and spinal cord. Satellite cells and Schwann cells are the two types of glial cells of the PNS. Schwann cells produce myelin around neural axon and are found in extremity nerves of the body.

E. Many neurotoxins have been used extensively in physiological studies of neurons. When comparing tetrodotoxin found in puffer fish and batrachotoxins from poison dart-frogs, the former had no effect on a neurons resting potential but completely stopped its action potential, whereas the later toxin immediately initiates depolarization of a neuron but prevents repolarization. Can your group hypothesize how these toxins affect the nerve transmission differently? arch entries or author Unread | * |

Hected to several cnidocytes through neural connections, help regulate groups of cnidocytes. Using the description above, deduce the different types of sensory cells that operate cnidocyte discharge including the mechanisms that induce an action potential. 2. Calmodulin is found in smooth muscle cells and performs a similar function to troponin in striated muscle fibers. However, calmodulin not only gets activated by Ca2+ but also slows the release of Ca2+ from the sarcoplasmic reticulum. How might this difference relate to the different kinds of contractions smooth muscles do in comparison to striated muscles? 3. A study of muscle fibers between chimpanzees and humans revealed that although muscle mass per body size are approximately equivalent, the ratio of red (slow) and white (fast) fibers were significantly different. Chimps tend to have a ratio of 30% red to 70% white where humans are 60/40 respectively. Speculate about what this ratio difference means in terms of muscle activity…
