Document Summary
Chapter 11 (part 1) read 11. 1, 11. 2, 11. 3, 11. 4. Learning outcomes: describe the general functions of the nervous system, define cns and pns, describe the two subcategories of the pns and the two subcategories of the motor division, describe the structure of a neuron. Describe the different types of neurons based on structure and function: list and describe the functions of the cns and pns glial cells. , define myelin sheath. How does the presence of myelin affect a neuron: describe gray matter, white matter, nucleus, ganglion. Coordination of the body"s organ systems: nervous system (electrical signals, endocrine system (chemical signals) Major functions of the nervous system: sensory input (detection of changes in the environment, integration (processing and coordinating, control of muscles and glands (effectors) usually responds to changes in environment, homeostasis, mental activity. Two major anatomical divisions of the nervous system: central nervous system, brain and spinal cord, integration, processing and coordinating sensory data and motor commands.
