What is the function of apocrine sweat glands?
What is the function of apocrine sweat glands?
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.
How do eccrine glands differ from apocrine glands?
Eccrine sweat glands are smaller sweat glands. They are coiled tubular glands that discharge their secretions directly onto the surface of the skin. Apocrine sweat glands are coiled tubular glands that discharge in the canals of hair follicles.
How are eccrine and apocrine glands similar?
Apocrine glands have a similar structure to eccrine glands but have a larger secretory component lined by either cuboidal or columnar epithelium and associated myoepithelial cells.
What is the function of eccrine gland?
Eccrine sweat glands help to maintain homoeostasis, primarily by stabilizing body temperature. Derived from embryonic ectoderm, millions of eccrine glands are distributed across human skin and secrete litres of sweat per day.
What is eccrine sweat glands?
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 is a characteristic of apocrine glands but not eccrine glands?
Apocrine sweat glands are associated with hair follicles; eccrine sweat glands are not. The secretion of apocrine sweat glands contains protein and fats that bacteria eat, resulting in odor; the secretion of eccrine sweat glands does not. Both types of glands secrete onto the body surface.
What is the difference between apocrine glands and merocrine glands?
The key difference between merocrine and apocrine sweat glands is that merocrine sweat glands excrete sweat directly onto the surface of the skin opening out through the sweat pore while apocrine sweat glands secrete sweat into the pilary canal of the hair follicle without opening directly onto the surface of the skin.
Where is eccrine sweat glands located?

Is eccrine and Merocrine 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 is the function of apocrine glands?
The apocrine sweat glands, associated with the presence of hair in human beings (as on the scalp, the armpit, and the genital region), continuously secrete a concentrated fatty sweat into the gland tube. Emotional stress stimulates contraction of the gland, expelling its contents. Skin bacteria break…
What are the functions of exocrine glands?
Exocrine Glands Definition. Exocrine glands are cellular sub-structures,organs,in a body that provide a system to secrete substances out and external to the body.
Where are apocrine sweat glands located?
It is located in the subcutaneous layer of the dermis; mainly in the deeper layers of the skin. The apocrine glands are mainly found in areolar of the breast, armpits, the area between anus and genitals, the eyelids and the ear.
What is the function of the apocrine sweat glands?
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.
