Example Question #2 : Anatomy, Physiology, And Pathophysiology

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

Possible Answers:

A rounding of the lens

Dilation of the pupil

Increase in intraocular pressure

Constriction of the pupil

A flattening of the lens

Correct answer:

Dilation of the pupil

Example Question #1 : Anatomy, Physiology, And Pathophysiology

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

Possible Answers:

faster than the rate in the SA node

the AV node does not contain pacemaker cells

slower 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

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.
