Question

Which of the following statements is FALSE?

a. Damage to the premotor cortex results in loss of motor skills programmed in that area but movement is still possible.
b. Damage to the visual association area can result in blindness.
c. Damage to the primary (somatic) motor cortex results in the loss of both voluntary muscle control and all reflexive contractions.
d. Damage to the primary auditory cortex results in the inability to interpret pitch, loudness, and location.

Answer 1

c. Damage to the primary (somatic) motor cortex results in the loss of both voluntary muscle control and all reflexive contractions.

Step-by-step explanation:

The primary motor cortex is an area in the brain that is responsible for the control and regulation of activities that involves movement of the body as well as the postures they body takes which we also refer to as motor skills.

The primary motor cortex sends signals in the form of nerve impulses to the brain and this in turn helps in the maintenance of the motor skills that is carried out by the body.

Not only does the damage to the primary (somatic) motor cortex results in the loss of both voluntary muscle control and all reflexive contractions, it also causes other losses such as constant contraction of the muscles also know as spasticity, involuntary muscle contraction also referred to as clonus.
