Conscious thought processes and all intellectual functions originate in the:
E. cerebral hemispheres
A highly specialized region of the sympathetic division that causes widespread sympathetic activation is found in the:
E. adrenal medulla
Typical sympathetic postganglionic fibers that release norepinephrine at neuroeffector junctions are classified as:
C. adrenergic
The autonomic division of the nervous system directs:
B. processes that maintain homeostasis
The sympathetic division of the ANS differs from the parasympathetic division of the ANS in that:
a. the sympathetic system has relatively longer preganglionic fibers than does the parasympathetic system
b. the sympathetic system promotes rest, relaxation, reponse, and nutrient uptake, while the parasympatheitic system increases alertness and metabolism
c.the postganglionic fibers of the sympathetic system are relatively longer than those of the parasympathetic system
d. the sympathetic system is more divergent than is the parasympathetic system
e. C and D
e. C and D
c.the postganglionic fibers of the sympathetic system are relatively longer than those of the parasympathetic system
d. the sympathetic system is more divergent than is the parasympathetic system
