Document Summary

* the nervous system is important when talking about viscera and visceral systems, particularly in the context of referred pain. * in general the nervous system is divided into somatic and autonomic parts. * the somatic division provides sensory innervation to the body walls, limbs and skin and it provides motor innervation to skeletal muscle and provides conscious/voluntary control of the skeletal muscle. The sensory division does things like touch, pressure and pain and it(cid:859)s all thi(cid:374)gs that we can perceive and consciously feel and motor goes to skeletal muscle and is important in movement. * the autonomic provides innervation for the viscera, blood vessels, glands and smooth muscle (cid:894)(cid:374)ot skeletal (cid:373)us(cid:272)le(cid:895). The auto(cid:374)o(cid:373)i(cid:272) is referred to as the (cid:858)su(cid:271)(cid:272)o(cid:374)s(cid:272)ious(cid:859) or (cid:858)i(cid:374)(cid:448)olu(cid:374)tary(cid:859) part of the nervous system (cid:449)e do(cid:374)(cid:859)t thi(cid:374)k (cid:272)o(cid:374)s(cid:272)iously a(cid:271)out it. * there are two neurons from the spinal cord to the target in the ans, particularly in the efferent part of it.
