  2. Pinealocyte - Wikipedia

    en.wikipedia.org/wiki/Pinealocyte

    The primary function of the pinealocytes is the secretion of the hormone melatonin, important in the regulation of circadian rhythms. [1] In humans, the suprachiasmatic nucleus of the hypothalamus communicates the message of darkness to the pinealocytes, and as a result, controls the day and night cycle. [ 2 ]

  3. Pineal gland - Wikipedia

    en.wikipedia.org/wiki/Pineal_gland

    The pineal gland (also known as the pineal body [1] or epiphysis cerebri) is a small endocrine gland in the brain of most vertebrates. It produces melatonin, a serotonin-derived hormone, which modulates sleep patterns following the diurnal cycles. [2] The shape of the gland resembles a pine cone, which gives it its name. [3]

  4. Epithalamus - Wikipedia

    en.wikipedia.org/wiki/Epithalamus

    The epithalamus also serves as a connecting point for the dorsal diencephalic conduction system, which is responsible for carrying information from the limbic forebrain to limbic midbrain structures. [ 4 ] [ 5 ] Some functions of its components include the secretion of melatonin from the pineal gland ( circadian rhythms ), regulation of motor ...

    en.wikipedia.org/wiki/Endocrine_system

    One of the most important functions of the hypothalamus—it is located in the brain adjacent to the pituitary gland—is to link the endocrine system to the nervous system via the pituitary gland.) Other organs, such as the kidneys , also have roles within the endocrine system by secreting certain hormones.

  6. Melatonin - Wikipedia

    en.wikipedia.org/wiki/Melatonin

    Melatonin, an indoleamine, is a natural compound produced by various organisms, including bacteria and eukaryotes. [1] Its discovery in 1958 by Aaron B. Lerner and colleagues stemmed from the isolation of a substance from the pineal gland of cows that could induce skin lightening in common frogs.

    en.wikipedia.org/wiki/Endocrine_gland

    The endocrine system is a network of glands and organs located throughout the body. It is similar to the nervous system in that it plays a vital role in controlling and regulating many of the body's functions. Endocrine glands are ductless glands of the endocrine system that secrete their products, hormones, directly into the blood.

    5-DHT or DHT is a male reproductive hormone that targets the prostate gland, bulbourethral gland, seminal vesicles, penis and scrotum and promotes growth/mitosis/cell maturation and differentiation. Testosterone is converted to 5-DHT by 5alpha-reductase, usually with in the target tissues of 5-DHT because of the need for high concentrations of ...

    en.wikipedia.org/wiki/Anterior_pituitary

    The anterior pituitary (also called the adenohypophysis or pars anterior) is a major organ of the endocrine system.The anterior pituitary is the glandular, anterior lobe that together with the posterior pituitary (or neurohypophysis) makes up the pituitary gland (hypophysis) which, in humans, is located at the base of the brain, protruding off the bottom of the hypothalamus.
