272 SECTION III Central & Peripheral Neurophysiology
- Sympathetic nerve activity
A) is essential for survival.
B) causes contraction of some smooth muscles and relaxation
of others.
C) causes relaxation of the radial muscle of the eye to dilate the
pupil.
D) relaxes smooth muscle of the gastrointestinal wall and gas-
trointestinal sphincter.
E) all of the above - Parasympathetic nerve activity
A) is essential for survival.
B) affects only smooth muscles and glands.
C) causes contraction of the radial muscle of the eye to allow
accommodation for near vision.
D) contracts smooth muscle of the gastrointestinal wall and
relaxes the gastrointestinal sphincter.
E) all of the above - Which of the following is correctly paired?
A) sinoatrial node : nicotinic cholinergic receptors
B) autonomic ganglia : muscarinic cholinergic receptors
C) pilomotor smooth muscle : β 2 -adrenergic receptors
D) vasculature of some skeletal muscles : muscarinic choliner-
gic receptors
E) sweat glands : α 2 -adrenergic receptors
