True-False Quiz

This activity contains 19 questions.

Question 1
1 Alpha-adrenergic receptors are always stimulatory whereas beta-adrenergic receptors are always inhibitory.
End of Question 1

Question 2
2 Close vision and accommodation are under parasympathetic control, whereas distant vision is under sympathetic control.
End of Question 2

Question 3
3 Lateral horns are absent in the sacral region of the spinal cord.
End of Question 3

Question 4
4 Lie detector tests depend on stimulation of the sympathetic system.
End of Question 4

Question 5
5 Mass reflex reaction is due to uncontrolled activation of the autonomic system. Somatic functions are normal.
End of Question 5

Question 6
6 Most the fine-tuning of body functions occurs without our awareness or attention.
End of Question 6

Question 7
7 Because the hypothalamus is the "boss" its influence is exerted directly on the ANS.
End of Question 7

Question 8
8 The autonomic system is NOT under voluntary control and therefore its activity is NOT regulated.
End of Question 8

Question 9
9 The parasympathetic division exerts short-lived, highly localized control over its effectors.
End of Question 9

Question 10
10 The sympathetic trunk extends only from the thorax to the lumbar region where the sympathetic fibers arise.
End of Question 10

Question 11
11 Transmission through the autonomic efferent is faster than through the somatic motor system.
End of Question 11

Question 12
12 Usually the parasympathetic and sympathetic stimulation of a target organ oppose each other, but sometimes they have cooperative effects.
End of Question 12

Question 13
13 As we age the efficiency of the autonomic nervous system decreases.
End of Question 13

Question 14
14 Taking a class in Yoga is generally very relaxing as a result of the stimulation of sympathetic effectors.
End of Question 14

Question 15
15 Both alpha and beta adrenergic receptors have several subclasses.
End of Question 15

Question 16
16 The main integration center of the ANS is the cerebral cortex.
End of Question 16

Question 17
17 The parasympathetic nervous system has little or no effect on blood vessels.
End of Question 17

Question 18
18 One of the major differences between the somatic and visceral motor divisions is the presence of two neurons in the visceral pathway.
End of Question 18
