Final answer:

The primary motor area is not located in the cerebellum.


Explanation:

The primary motor area is in the cerebellum, as stated in one of the options, is not true.

The primary motor cortex, located in the frontal lobe's precentral gyrus, is responsible for voluntary skeletal muscle movements. It contains a motor homunculus, where body parts are represented based on the number of motor neurons rather than the actual size of the body part.

Facial movements occupy a significant portion of the primary motor area, where muscles responsible for fine movements have more cortical space, like those controlling fingers and the lower face.
