the sensory and control apparatus consisting of a network of nerve cells

of or relating to the sympathetic nervous system

the part of the nervous system of vertebrates that controls involuntary actions of the smooth muscles and heart and glands

any of several nerves of the sympathetic part of the autonomic nervous system that innervate viscera and blood vessels

a large plexus of sympathetic nerves in the abdomen behind the stomach

receptors postulated to exist on nerve cell membranes of the sympathetic nervous system in order to explain the specificity of certain agents that affect only some sympathetic activities (such as vasoconstriction and relaxation of intestinal muscles and contraction of smooth muscles)

receptors postulated to exist on nerve cell membranes of the sympathetic nervous system in order to explain the specificity of certain agents that affect only some sympathetic activities (such as vasodilation and increased heart beat)
