Infobox references. Dehydroepiandrosterone (DHEA), also known as androstenolone, is an endogenous steroid hormone precursor. [4] It is one of the most abundant circulating steroids in humans. [5] DHEA is produced in the adrenal glands, [6] the gonads, and the brain. [7]
Dehydroepiandrosterone (DHEA) is a steroid hormone produced in the adrenal cortex from cholesterol. [5] It is the primary precursor of both the androgen and estrogen sex hormones. DHEA is also called dehydroisoandrosterone or dehydroandrosterone. Androstenedione (A4) is an androgenic steroid produced by the testes, adrenal cortex, and ovaries.
Dehydroepiandrosterone sulfate, abbreviated as DHEA sulfate or DHEA-S, also known as androstenolone sulfate, is an endogenous androstane steroid that is produced by the adrenal cortex. [1] It is the 3β- sulfate ester and a metabolite of dehydroepiandrosterone (DHEA) and circulates in far greater relative concentrations than DHEA. [2]
15632. Anatomical terminology. [edit on Wikidata] The adrenal cortex is the outer region and also the largest part of the adrenal gland. It is divided into three separate zones: zona glomerulosa, zona fasciculata and zona reticularis. Each zone is responsible for producing specific hormones. It is also a secondary site of androgen synthesis.
DHEA supplements were shown to help women with adrenal insufficiency, improving depression, anxiety, mood and overall well-being. Research in men and women with Addison’s disease showed that 50 ...
Neurosteroids are synthesized from cholesterol, which is converted into pregnenolone and then into all other endogenous steroids. Neurosteroids are produced in the brain after local synthesis or by conversion of peripherally-derived adrenal steroids or gonadal steroids. They accumulate especially in myelinating glial cells, from cholesterol or ...
A neurohormone is any hormone produced and released by neuroendocrine cells (also called neurosecretory cells) into the blood. [1][2] By definition of being hormones, they are secreted into the circulation for systemic effect, but they can also have a role of neurotransmitter or other roles such as autocrine (self) or paracrine (local) messenger.
The pituitary gland or hypophysis is an endocrine gland in vertebrates. In humans, the pituitary gland is located at the base of the brain, protruding off the bottom of the hypothalamus. The human pituitary gland is oval shaped, about the size of a chickpea, [2] and weighs 0.5 grams (0.018 oz) on average.
