Movement:
1.Contrast the 3 types of muscle fibers (slow, fast, and intermediate). Include energy source, mitochondria content, and performance. Explain each.
2.Describe the structure of a muscle, including the following terms: myosin, actin, sarcomere, myofibril, fiber, bundle.
3.Describe the steps involved in a muscle contraction, using the terms actin, myosin, troponin, tropomyosin, and calcium. Include where the calcium is stored and released. (2pts)
4.Contrast flexion and extension. Give an example by describing the movement of a part of our body and the opposing muscles that cause the movement.
Nerves:
5.Describe what the 3 types of neurons discussed in class do (sensory, motor, inter-). Contrast neuron cell body, axon, and dendrites.
6.Describe what resting potential is and how neurons maintain it.
7.Explain the events that occur during an action potential, being sure to describe what causes depolarization and repolarization. How do Schwann cells (glial cells) aid in the movement of depolarization along an axon? (2pts)
8.Describe what happens when an action potential reaches a synapse. Include the influence of calcium and neurotransmitters.
9.Contrast the somatic and autonomic peripheral nervous system by briefly describing what they do and giving 3 examples of each. (2pts)
10.List the functions of different brain regions (list the region names and the functions of each). (2pts)
