Somatic Nervous System

Parasympathetic Nervous System

None of the given answers is correct

Central Nervous System

Autonomic Nervous System

Correct answer:

Autonomic Nervous System

Explanation:

The sympathetic nervous system is a part of the autonomic nervous system. The parasympathetic nervous system comprises the other part of the autonomic nervous system.

Example Question #3 : Anatomy, Physiology, And Pathophysiology

Activation of the sympathetic nervous system will cause which of the following to occur?

Possible Answers:

A flattening of the lens

Increase in intraocular pressure

A rounding of the lens

Constriction of the pupil

Dilation of the pupil

Correct answer:

Dilation of the pupil

Explanation:

Activation of the sympathetic nervous system will cause dilation of the pupil. Activation of the parasympathetic nervous system will cause constriction of the pupil.

Example Question #4 : Anatomy, Physiology, And Pathophysiology

The intrinsic rate of the pacemaker cells in the AV node is:

Possible Answers:

the AV node does not contain pacemaker cells

faster than the rate in the SA node

varies (sometimes faster, sometimes slower than the rate in the SA node)

equal to the rate in the SA node

slower than the rate in the SA node

Correct answer:

slower than the rate in the SA node

Explanation:

The intrinsic rate of depolarization is slower among the pacemaker cells in the AV node compared to the rate in the SA node.
