Document Summary
Autonomic functions (heartbeat, digestion, blood pressure, etc: important for homeostasis. Central nervous system: brain and nerve cord (spinal cord in vertebrates) Peripheral nervous system: all neurons and their projections that are outside the cns. Sensory inputs from pns and cns (sight, odor and taste) Information processing by cns (thinking of yummy food) Commands from cns and pns control body activities (salvation) Afferent division- transmits sensory info (sensory neurons) to central nervous system. Efferent division- transmits motor information (motor neurons) away from cns. Autonomic nervous system (involuntary response; controlling blood pressure, etc. : parasympathetic division (don"t worry about, sympathetic division(don"t worry about) Efferent (motor) systems: somatic nervous system, voluntary responses a. i. Motor neurons control skeletal muscles: autonomic nervous system. Involuntary- usually cannot be consciously controlled a: regulates homeostasis b. i. Brain stem- information relay; autonomic control of heart, lungs, and digestive system. Integrates information from other nervous system inputs and creates appropriate outgoing signals.
