Damage to the primary motor cortex in the right cerebral cortex results in the loss of ____.

A) sensation on the left side of the body
B) sensation on the right side of the body
C) voluntary movement on the right side of the body
D) voluntary movement on the left side of the body
E) the ability to speak

The primary motor cortex controls voluntary movements of the body, with the left side of the primary motor cortex controlling movements on the right side of the body, and the right side controlling movements on the left side of the body. Therefore, damage to the primary motor cortex in the right cerebral cortex would result in the loss of voluntary movement on the left side of the body.
