I just don't get what makes them different. • (4 votes) kenzie 10 years agoPosted 10 years ago. Direct link to kenzie's post “Really, there is minimal ...” Really, there is minimal difference. The primary difference lies in the receptors that they have a higher affinity for. Noradrenaline (NE) prefers alpha and beta 1 receptors while adrenaline (E) has greater specificity for only alpha receptors. Sorry for the late response and it is really basic as I don't know how much biochemistry you know. Trav.F32 9 years agoPosted 9 years ago. Direct link to Trav.F32's post “At the end of this video ...” At the end of this video you said that these were the parts of the CNS. I thought they were part of the PNS. Isn't the CNS just basically consist of the brain and spinal cord? • (6 votes) eira 9 years agoPosted 9 years ago.

Direct link to Joanne's post “Somatic Nervous System is...” Somatic Nervous System is the one that allows conscious (voluntary) control of skeletal muscles. Autonomic N. S. has the unconscious (involuntary) control of the body and it has 2 branches, the Sympathetic and Parasympathetic NS.

Direct link to William H's post “The same neurotransmitter...” The same neurotransmitters can be found in both the sympathetic and parasympathetic nervous systems although the concentration may be more. For pre and post I think you refer to pre and post synaptic. Pre is the starting neuron, post is the one that receives the signal. (3 votes) lubnashaikh04 3 years agoPosted 3 years ago.

If you go to the open encyclopedia, Wikipedia, under nervous system there is a diagram that illustrates the system well. The autonomic and somatic nervous system s are efferent or motor command pathways of the peripheral n. s. (2 votes)Want to join the conversation?
Binding to alpha receptors causes a constriction of the vessel walls; binding to beta-1 receptors causes increased force and speed of cardiac contractions, increased irritability of the heart, &c.; and binding to beta-2 receptors causes bronchodilatation and vasodilation in the walls of the blood vessels of muscles.
Raja said, "two major divisions of the central nervous system", but meant "two major divisions of the peripheral nervous system".
Raja said "the sympathetic nervous system use NE", but meant "the pre-ganglionic nerves of the sympathetic nervous system use ACh and the post-ganglionic nerves use NE."
Are you saying that autonomic is involuntary or somatic is voluntary?
Also you can go to Wikipedia, and look them up there. I would use the book, and then use Wikipedia for more detail.
