Question

Folding of the _________ allows for its __________–square-foot surface area to fit into the skull. A. cerebral cortex . . .1.5 B. corpus callosum . . . 2.5 C. right hemisphere . . . 2.5 D. cerebrum . . .1.5

Answer 1

Answer:

A. cerebral cortex . . .1.5

Explanation:

The human brain consists of various sections and these includes;

I. Anterior Cingulate Cortex (ACC) which resembles a bow or collar surrounding the frontal part of the corpus callosum. This is the frontal part of the cingulate cortex which helps to make complex cognitive functions such as impulse control, decision-making, emotions and empathy.

II. Ventral prefrontal cortex in humans are interconnected with the brain and are responsible for the processing of risk, empathy, fear and social decision-making

III. The Cerebral Cortex: this part of the brain primarily comprises of grey matter, foldable sheets of neurons and forms its outermost layer. Therefore, cerebral cortex is known as the outermost layer of the brain (cerebrum) and thus, makes up half of its weight. It is about 2.5 millimeters in thickness and as such it's able to fold.

Hence, folding of the cerebral cortex allows for its 1.5–square-foot surface area to fit into the skull.
