somatic sensory fibers
viseral sensory fibers
somatic snesoiry fibers do this
convery impulses from skin skeletal muscles and joints to cns
viseral sensory fibers
convery impulses from viseral organs to cns
sensory division is
afferent-goes toward cns
motor division is
efferent-goes away from cns
2 devisions of motor division
somatic
autonomic
somatic nervous system
volentary control away-impulses from cns to skeletal muscle
autonomic nervous system
involentary system-viseral motor nerve fibers
smooth muscle, cardiacd, and glands
autonomic nervous ssytem 2 divisions
sympathetic and parasympathetic
symapathetic system does this
mobilizes body systems during activity
parasympattic system
