Apocrine sweat gland An apocrine sweat gland (/ ˈ æ p ə k r ə n, - ˌ k r aɪ n, - ˌ k r iː n /; from Greek apo– away and krinein to separate) is composed of a coiled secretory portion located at the junction of the dermis and subcutaneous fat, from which a straight portion inserts and secretes into the infundibular portion of the hair follicle.

RIXIMKA DUMARKA Endocrine glands are glands of the endocrine system that secrete their products, hormones, directly into the blood rather than through a duct. The major glands of the endocrine system include the pineal gland, pituitary gland, pancreas, ovaries, testes, thyroid gland, parathyroid gland, hypothalamus and adrenal glands.The hypothalamus and pituitary gland are neuroendocrine organs.Local chemical messengers, not generally considered part of the endocrine system, include autocrines, which act on the cells that secrete them, and paracrines, which act on a different cell type nearby.he hypothalamus and pituitary gland are neuroendocrine organs.

Oxyphil cell (pathology) The endocrine system refers to the collection of glands of an organism that secrete hormones directly into the circulatory system to be carried towards distant target organs. The major endocrine glands include the pineal gland, pituitary gland, pancreas, ovaries, testes, thyroid gland, parathyroid gland, hypothalamus, and adrenal glands. The endocrine system is in contrast to the exocrine system, which secretes its hormones to the outside of the body using ducts.

gland 1. 1  a. Any of various organs or cell groups, such as the adrenal glands and the salivary glands, that are of endothelial origin and secrete a substance that is used or excreted by the body. 2  b. Any of various organs, such as lymph nodes, that resemble true glands but perform a nonsecretory function.

Apocrine sweat gland The apocrine gland secretes an oily fluid with proteins, lipids, and steroids that is odorless before microbial activity. It appears on the skin surface mixed with sebum, as sebaceous glands open into the same hair follicle. Unlike eccrine sweat glands, which secrete continuously, the apocrine glands secrete in periodic spurts.

Endocrine system Main glands of the endocrine system. Note that the thymus is no longer considered part of the endocrine system, as it does not produce hormones. [edit on Wikidata] The endocrine system is the collection of glands of an organism that secrete hormones directly into the circulatory system to be carried towards distant target organs. The phenomenon of biochemical processes' serving to regulate distant tissues by means of secretions directly into the circulatory system is called endocrine signaling.

Merocrine Merocrine (or eccrine) is a term used to classify exocrine glands and their secretions in the study of histology. A cell is classified as merocrine if the secretions of that cell are excreted via exocytosis from secretory cells into an epithelial-walled duct or ducts and thence onto a bodily surface or into the lumen.

Exocrine gland Exocrine glands are glands that produce and secrete substances onto an epithelial surface by way of a duct. Examples of exocrine glands include sweat, salivary, mammary, ceruminous, lacrimal, sebaceous, and mucous.Exocrine glands are one of two types of glands in the human body, the other being endocrine glands, which secrete their products directly into the bloodstream.xocrine glands contain a glandular portion and a duct portion, the structures of which can be used to classify the gland. 1  The duct portion may be branched (called compound) or unbranched (called simple).

Exocrine gland Exocrine glands are one of two types of glands in the human body, the other being endocrine glands, which secrete their products directly into the bloodstream.he liver and pancreas are both exocrine and endocrine glands; they are exocrine glands because they secrete products— bile and pancreatic juice —into the gastrointestinal tract through a series of ducts, and endocrine because they secrete other substances directly into the bloodstream.
