Which of the following is true concerning the development of the nervous system after birth?

a) the hypothalamus is the last CNS structure to mature

b) anencephaly is normally easily corrected.

c) most people, after age 65 are actually exhibiting signs of true senility.

d) all of these are false.

Expert Solution

Ans-(c) . Most people ,after the age of 65 are actually exhibiting signs of true senility.

Senile usually refers to or relates to exhibiting characteristic of old age. Most of the times used to refer to decline in mental abilities such as memory, loss or confusion, as people age. This is mostly seen in most of the people over the age of 65.

(a) is false because because the spinal cord and brain stem are developed and organs responsible for major functions like breathimb, heartbeat, circulation, sleeping, swallowing are developed by birth. While the higher regions like limbic system and cerebral cortex mature later. So hypothalamus is not last to mature but mature earlier.

(b). False because anencephaly cannot be cured. Anencephaly is defect in formation of baby's neural tube during development. Thus the baby is born with underdeveloped brain and incomplete skull. Such baby may be still born or survive few days to few hours after birth.
