Document Summary
Chapter 11 the neuromuscular system and physical activity. Identify three major structural components of the central nervous system that control human movement. Diagram the anterior motoneuron and discuss its role in human movement. Draw and label the basic components of a reflex arc. Define motor unit, neuromuscular junction, autonomic nervous system, excitatory postsynaptic potential, inhibitory postsynaptic potential. Describe the function of muscle spindles and golgi tendon organs. Draw and label a skeletal muscle fiber"s ultrastructural components. Describe the sequence of chemical and mechanical events during skeletal muscle contraction and relaxation. Contrast slow-twitch and fast-twitch muscle fiber characteristics, including subdivisions. Outline muscle fiber-type distribution patterns among diverse groups of elite athletes. Explain how training modifies muscle fibers and fiber types. Pns: 12 cranial nerves, 31 pairs of spinal nerves. 6 main divisions: medulla oblongata, pons, midbrain, cerebellum, diencephalon, telencephalon. Encased by 33 vertebrae seperated by intervertebral discs. Pyrimidal tract: transmits impulses downward through spinal cord.
