Pineal gland secretes the hormone melatonin at night with a circadian rhythm. The synthesis and secretion of melatonin are stimulated at night by norepinephrine released by sympathetic postganglionic neurons projecting from the superior cervical ganglia.

This chapter describes the pineal gland’s structure, related hormones, and physiology. The pineal gland (epiphysis cerebri) is a small (100–150 mg in humans), unpaired central structure. The mammalian pineal is a secretory organ, whereas in fish and amphibians it is directly photoreceptive (the ‘third eye’) and in reptiles and birds it has a mixed ...

Neonatal Network, 2000
The pineal gland is located posterior to the midbrain and is the site of melatonin production. Research on pineal gland function in neonates is very limited. This article will discuss pineal gland development and the possible relationship between melatonin production and sudden infant death syndrome.

The activity of ornithine decarboxylase was assayed in several organs (thymus, testes, prostate gland, liver, kidneys, adenohypophysis, anterior hypothalamus, and adrenals) taken from adult male rats killed at seven day interval up to six weeks after pinealectomy.

Pineal Gland Tumor Microenvironment
2020A wide and heterogeneous variety of tumors develop from the pineal gland. Pineal parenchymal tumors, germ cell tumors, and glial tumors represent most of them. The molecular profiles and tumor microenvironment play a key role in the development and progression of pineal gland tumors. Consequently, they represent important factors that may determine the

The pineal gland plays a key role in the control of the daily and seasonal rhythms in most vertebrate species. In mammals, rhythmic melatonin (MT) release from the pineal gland is controlled by the suprachiasmatic nucleus via the sympathetic nervous system.

Comparative Physiology: Pineal Gland
Annual Review of Physiology, 1973Literature on the endocrinologic function of the pineal gland is reviewed. The pineal gland appears to have an inhibitory effect on gonadtoropin release. It is possible since no hypothalamic inhibiting factors have been indentified with the control of luteinizing hormone (LH) and follicle stimulating hormone synthesis and release by the anterior ...
