What is inside your Pineal Gland

The pineal gland is made of Rods and Cones…cones help us see lower wavelength and peripheral…spirits are always seen peripherally…very rarely centrally. low wavelength of visual light….there is something to our pineal and infra red and ultraviolet. something that activates our pineal to sense what is beyond…like a magnet to a tv…or photo sensitive proprioception.

The pineal gland, the most enigmatic of endocrine organs, has long been of interest to anatomists. Several millennia ago it was thought to control the flow ofmemories into consciousness. The 17th-century French philosopher-mathematician René Descartes concluded that the pineal gland was the seat of the soul. A corollary notion was that calcification of the pineal caused psychiatric disease, but modern imaging techniques revealed that the pineal gland becomes more or less calcified in most people.d1ec16ae0d6cb8c5b3c34234ab49f20b

Anatomy of the pineal gland

The pineal gland is located behind the third cerebral ventricle in the midline (between the two cerebral hemispheres) of the brain. Its name is derived from its shape, which is like that of a pine cone (Latin pinea). In adult humans it is about 0.8 cm (0.3 inch) long and weighs approximately 0.1 gram (0.004 ounce). The gland is relatively large in children and begins to shrink with the onset of puberty. It has a rich supply of adrenergic nerves that greatly influence its function. Microscopically, the gland is composed of pinealocytes (rather typical endocrine cells except for extensions that mingle with those of adjacent cells) and supporting cells that are similar to the astrocytes of the brain. In adults, small deposits of calcium often make the pineal body visible on X-rays.


Endocrine function of the pineal gland

In humans and other animals, the pineal gland produces hormones that have important endocrine functions. For example, in several vertebrate species, pineal hormones influence sexual development, hibernation, and seasonal breeding. The pineal gland contains several neuropeptides and neurotransmitters, such assomatostatin, norepinephrine, and serotonin. The major pineal hormone, however, is melatonin, a derivative of the amino acid tryptophan. Melatonin was first discovered because it lightens amphibian skin, an effect opposite to that ofadrenocorticotropic hormone and melanocyte-stimulating hormone of the anterior pituitary gland.


The secretion of melatonin is increased by sympathetic nervous systemstimulation. In humans, melatonin secretion increases soon after a person is placed in the dark and decreases soon after exposure to light. A major action of melatonin that has been well documented in animals is to block the secretion ofgonadotropin-releasing hormone by the hypothalamus. This results in decreased secretion of gonadotropins (e.g., luteinizing hormone and follicle-stimulating hormone) by the pituitary gland. In humans, however, the function of melatonin is less well understood. Its production is high in infancy and childhood and declines with age, and abnormally high levels of melatonin in children are associated with delayed sexual development.


Melatonin has been used to treat conditions such as depression, insomnia, and jet lag, but its efficacy for these purposes is controversial.
