Question 12 • 670417 Psychology S1 - MOSELEY, MELISSA K

Which of the following characteristics of the pineal gland is not correct?

Answer
A
The pineal gland is located in the brain, above the cerebellum.
B
The pineal gland acts as an internal clock.
C
The pineal gland regulates sleep and waking cycles.
D
The pineal gland regulates salt and water levels.

Explanation

The pineal gland produces melatonin, which helps regulate the body’s internal clock and sleep–wake cycles. It is located in the brain, above the cerebellum. Salt and water balance is regulated mainly by hormones such as antidiuretic hormone and aldosterone, not by the pineal gland, so “regulates salt and water levels” is the incorrect characteristic.
