ANATOMY

Detailed explanation-1: -The main function of the pineal gland is to receive information about the state of the light-dark cycle from the environment and convey this information by the production and secretion of the hormone melatonin.

Detailed explanation-2: -Pineal factors influence testicular function by interaction with the neuroendocrine system to affect pituitary gonadotropin secretion. The higher neural centers appear to be responsive to indoles and via the releasing factors give rise to changes in pituitary content and circulating levels of FSH and LH.

Detailed explanation-3: -The pineal gland is a very small gland in the centre of the brain shaped like a pine cone, which is where it gets its name. It is part of the endocrine system. It produces a hormone called melatonin.

Detailed explanation-4: -Basal testosterone secretion which can be enhanced or reduced is not affected by pineal effluent. This result indicates that pineal products have no effect on testosterone biosynthesis.

Detailed explanation-5: -Located deep in the center of the brain, the pineal gland was once known as the “third eye.” The pineal gland produces melatonin, which helps maintain circadian rhythm and regulate reproductive hormones.
