Ch 7 the nervous system notes lisa peck: organization of the nervous system (pp 222-224) Nervous system- the master controlling and communicating system of the body. Regulating and maintaining homeostasis nervous system - fast-acting control via electrical impulses endocrine system- slow-acting control via hormones release into the blood. Central nervous system (cns) consists of: brain spinal cord functions: integrating centerinterpret incoming sensory information command centerissue instructions based on past experience & current conditions. Functional classification (pp 223-224) only deals with peripheral nervous system (pns) 2: sensory (afferent) division- nerve fibers that carry impulses to the cns from sensory receptors located throughout body sensory fibers types: 1. somatic sensory fibers- delivering impulses from the skin, skeletal muscles, & joints. 2. visceral sensory fibers- transmitting impulses from the visceral organs: motor (efferent) division- nerve fibers that carry impulses from the cns to effector organs ossicles and glands, bringing about a motor response.
