Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which gland controls sleep/ wake cycles and is thought to have been a “third eye” in our evolutionary past?
A
Hypothalamus
B
Pituitary
C
Pineal
D
Lacrimal
Explanation: 

Detailed explanation-1: -The pineal gland was commonly called the “third eye” for many reasons, including its location deep in the center of the brain and its connection to light via the circadian rhythm and melatonin secretion.

Detailed explanation-2: -The main function of the pineal gland is to receive and convey information about the current light-dark cycle from the environment via the production and secretion of melatonin cyclically at night (dark period) (6, 7).

Detailed explanation-3: -The physical structure most closely related to the third eye chakra is the pituitary gland-the queen of the endocrine system. Headaches, hormone imbalances, nightmares, indecision, burnout, and lack of purpose are all common manifestations when there’s an imbalance in the third eye.

Detailed explanation-4: -Melatonin secreted by the pineal gland is an important part of the body’s circadian timing system and can synchronise daily rhythms (see the articles on jet lag and circadian rhythm sleep disorders). Melatonin is secreted more when it is dark which explains melatonin’s role in sleep.

Detailed explanation-5: -What does the hypothalamus do? The hypothalamus is a small area in the center of the brain. It helps produce hormones that regulate heart rate, body temperature, hunger, and the sleep-wake cycle.
