What is the function of the eccrine glands quizlet?
Both types of glands secrete onto the body surface. Eccrine glands cool the body, apocrine glands function as scent glands.
What are the functions of the eccrine and apocrine sweat glands?
Eccrine glands are found all over the body and secrete a watery product that cools the skin. Apocrine sweat glands are mainly found in the armpits and perianal area, and secrete a more viscous, odorous product.
What is the function of the apocrine gland?
description. Apocrine sweat glands, which are usually associated with hair follicles, continuously secrete a fatty sweat into the gland tubule. Emotional stress causes the tubule wall to contract, expelling the fatty secretion to the skin, where local bacteria break it down into odorous fatty acids.

What’s the difference between eccrine and apocrine glands?
Eccrine glands occur over most of your body and open directly onto the surface of your skin. Apocrine glands open into the hair follicle, leading to the surface of the skin. Apocrine glands develop in areas abundant in hair follicles, such as on your scalp, armpits and groin.
What is apocrine sweat glands?
Apocrine glands in the skin and eyelid are sweat glands. Most apocrine glands in the skin are in the armpits, the groin, and the area around the nipples of the breast. Apocrine glands in the skin are scent glands, and their secretions usually have an odor.
What is the function of the sebaceous glands quizlet?
What is the function of the sebaceous glands? Sebaceous glands secrete sebum, which keeps the hair and skin soft, pliable, and waterproof.
What stimulates eccrine and apocrine sweat glands?
Emotional sweating is stimulated by stress, anxiety, fear, and pain, it is independent of ambient temperature. Acetylcholine acts on the eccrine glands and adrenaline acts on both eccrine and apocrine glands to produce sweat.
What is the function of sweat glands and sebaceous glands?
Sweat glands
The body of the gland is made up of a coiled tube, surrounded by a good blood supply, and a duct, which opens onto the skin surface through a pore. Other glands open into the hair follicles after puberty. The important function of the sweat glands is to form the fluid sweat.
Where is eccrine gland found in the body?
Eccrine sweat glands are simple, coiled, tubular glands present throughout the body, most numerously on the soles of the feet. Thin skin covers most of the body and contains sweat glands, in addition to hair follicles, hair arrector muscles, and sebaceous glands.
Which cells are responsible for the secretions of eccrine sweat glands?
Morphological features of eccrine sweat glands
Dark and clear cells are secretory cells, whereas myoepithelial cells support the glands mechanically and create a major niche for gland stem cells (3,18,22).
What is the function of the Arrector pili muscle quizlet?
The arrector pili muscles are small muscles attached to hair follicles in mammals. Contraction of these muscles causes the hairs to stand on end, known colloquially as goose bumps.
Are eccrine glands more numerous?
The 2−4 million eccrine sweat glands distributed over the body surface regulate the internal body temperature by evaporative heat loss. These sweat glands are most numerous on the forehead, palms, and soles (~600−700 glands per square centimeter) and least numerous on the back (~64 glands per square centimeter).
What are the functions of the integumentary system quizlet?
What are the functions of the integumentary system? Its main function is to act as a barrier to protect the body from the outside world. It also functions to retain body fluids, protect against disease, eliminate waste products, and regulate body temperature.
What is another name for the sudoriferous glands quizlet?
Another name for sweat gland is sudoriferous gland.
What is the difference between apocrine and merocrine glands?
Apocrine sweat glands are found associated with hair follicles and only become active at puberty. Merocrine sweat glands are found throughout the skin and produce a watery sweat from birth.
What are the functions of merocrine sweat glands?
Merocrine sweat glands are coiled tubular glands that discharge their secretions directly onto the surface of the skin. The clear secretion produced by merocrine glands is termed sweat, or sensible perspiration.
What is the function of simple cuboidal epithelium in apocrine sweat glands?
Apocrine sweat glands are typically larger and more productive than eccrine glands. They are characterized by a simple cuboidal epithelium and widely dilated lumen that stores the secretory product. Secretion from apocrine glands contains protein, lipid, carbohydrate, ammonium and other organic compounds.
What is a function of the secretions from sebaceous glands?
The sebaceous gland is an organ located in the dermis. Its role is to synthesise and secrete sebum which is a component of the hydrolipidic film. The purpose of sebum is to protect the skin from damages caused by external factors and from dehydration. Sebum also maintains the suppleness of skin and hair.
What are sebaceous glands where are they found what functions do they accomplish?
The sebaceous glands are microscopic glands in the skin that secrete an oily/waxy matter, called sebum, to lubricate and waterproof the skin and hair of mammals. In humans, they are found in greatest abundance on the face and scalp, though they are distributed throughout all skin sites except the palms and soles.
Are merocrine and eccrine the same?
Merocrine (or eccrine) is a term used to classify exocrine glands and their secretions in the study of histology. … The term eccrine is specifically used to designate merocrine secretions from sweat glands (eccrine sweat glands), although the term merocrine is often used interchangeably.
What organ system contains the eccrine sweat glands?

Can you sweat blood?
Bloody sweating is called hematohidrosis, true hematohidrosis occur in bleeding disorders. [1] It may occur in individuals suffering from extreme levels of stress. Around the sweat glands, there are multiple blood vessels in a net-like form, which constrict under the pressure of great stress.
