In humans, the pineal gland controls our biorhythms and works in conjunction with the hypothalamus gland to control our thirst, hunger, sexual desire and biological clock that is associated with the aging process.he high melatonin levels in children are believed to inhibit their sexual development until melatonin levels decrease when puberty begins. Melatonin is created when the amino acid tryptophan is converted into the neurotransmitter serotonin, which is in turn synthesized into melatonin.
Sweat comes from exocrine glands. The pituitary gland is an endocrine gland that produces hormones. The endocrine system regulates the body's organ function using hormone-based signals. The pineal gland secretes melatonin, which promotes sleep.ndocrine glands secrete substances directly into the bloodstream. Exocrine glands tend to be relatively simple and have local effects, while endocrine ones release hormones that travel throughout the body. Most glands form in the embryo from epithelial tissue.
