Chapter 15, Problem 10DYKB
Summary Introduction
Introduction:
The neurons, which release and synthesize norepinephrine (NE), is known to be the adrenergic neurons and the receptors, which bind to them, are the adrenergic receptors. The adrenergic receptors can be of 2 types; alpha and beta.

Nicotinic receptors bind
A. acetylcholine and allow chloride ions to exit the cell.
B. acetylcholine and allow sodium ions to enter the cell.
C. muscarine and increase the contractility of intestinal muscle.
D. norepinephrine and can either stimulate or inhibit the cell.
E. norepinephrine and allow potassium entry, thereby exciting the cell.
Catecholamine (Epinephrine)-blockers are often used as a treatment to dilate blood
vessels and therefore decrease arterial blood pressure (as a treatment for
hypertension). This fact is excellent evidence to prove that the nervous system
normally controlling the diameter of the arterial blood vessels is the:
a. Somatosensory nervous system
b. Sympathetic nervous system
c. Reticular attenuating nervous system
d. Parasympathetic nervous system
What do multiple sclerosis and ALS (amyotropic lateral sclerosis) have in common?a. They both are more common in young men than in young women.b. They both impair the initiation of action potentials.c. They both damage the myelin sheath, disrupting action potential transmission.d. They both impair nerve function in the peripheral nervous system
