Document Summary
Anu bio 202 apii final exam study. Master controlling and communicating system of the body via electrical impulses. 1)uses sensory receptors to monitor changes inside and outside the body which are called stimuli, gathered information is called sensory input. 2)processes and interprets the input and decides what should be done. 3)effects a response by activating muscles or glands via motor output. Central nervous system (cns)= brain and spinal cord. Interpret incoming sensory information and issue instructions based on past experience and current conditions. Peripheral nervous system (pns) (12) pair cranial nerves and (31) pair spinal nerves. Cranial nerves carry impulses to and from the brain. Spinal nerves carry impulses to and from the spinal cord. Sensory fibers delivering impulses from the skin, skeletal muscles, and joints are called somatic. Sensory from the visceral organs are called visceral sensory fibers or visceral afferents. Motor (efferent) output from the cns that activates muscles and glands.
