c. association area of processing
d. none of the above

The primary point of activation for voluntary movement in the cortex is:
a. the post-central gyrus

c. Heschl’s gyrus
d. Supramarginal gyrus

Expert Solution

Question 1:

Answer: Primary activation region

Explanation: Primary visual cortex of occipital lobe is also known as brodmanm area17 or V1 is a primary activation region the primary role of brodmann area 17 is to control vision.

Question 2:

Answer: Primary activation region

Explanation: Temporo - Occipito - parietal region is a primary activation region. The temporal region consist of primary auditory region which plays a primary role in hearing. The occipital lobe consist of primary visual cortex which has a primary role in vision. Parietal region consist of primary somatosensory region it send the somato sensory stimuli it helps to identify the weight, shape of the object. Thus the three regions perform primary functions of the body so they are primary activation region.

Question 3:

Answer: Precentral gyrus

Explanation: Precentral gyrus is located in the frontal lobe of the brain it present parallel to the central sulcus and it extend up to Precentral sulcus. The primary motor cortex is present in the precentral gyrus. it is mainly responsible for voluntary movements.
