A nursing instructor is describing Parkinsonism to a group of nursing students. When discussing the underlying cause of the symptoms, the instructor explains the depletion of dopamine in which of the following?
a. Central nervous system
b. Smooth muscle
c. Skeletal muscle
d. Peripheral nervous system

A. Central nervous system

Explanation:

Dopamine is a neurotransmitter which plays the role of sending signals to the part of the brain that is responsible for movement and coordination.

When the dopamine levels are low , the individual isn’t able to move well and loses coordination because of the little or absence of signals to the part of the brain that controls these aspects.
