Which type of sweat gland secretes a pale sweat, which doesn’t play a significant role in cooling?
(a) Exocrine
(b) Apocrine
(c) Holocrine
(d) Endocrine
Solution
Small tubular structures of the skin that contain sweat are sweat glands. A coiled secretory portion situated at the junction of the dermis and subcutaneous fat is the gland that generates pale sweat that does not play a significant role in cooling.
Complete answer:
The apocrine sweat glands are often restricted in humans to the axillae (armpits), areola and nipples of the breast, ear canal, eyelids, nostril wings, perianal region, and some parts of the outer genitalia. They are not important to human cooling.
The apocrine sweat gland ("away" from Greek apo and "separate" from krinein) consists of a coiled secretory part at the junction of the dermis and subcutaneous fat from which a straight part inserts and secretes into the infundibular portion of the hair follicle.
Additional Information: However, most non-primate species have apocrine sweat glands over the greatest portion of their body. At each hair follicle, domestic animals such as dogs and cats have apocrine glands but eccrine glands only in the footpads and snout. Like those in humans, their apocrine glands develop an odorless, sticky, opaque secretion that gains its characteristic odor upon the decomposition of bacteria.
Sweat glands are small tubular structures of the skin that contain sweat, also known as sudoriferous or sudoriferous glands, from Latin sudor, meaning 'sweat'. Sweat glands are a type of exocrine gland, which is a type of gland that develops and secretes substances through a duct onto an epithelial surface.
There are two major types of sweat glands, which vary in structure, function, secretory substance, excretion mechanism, anatomical distribution, and species distribution:
-Eccrine sweat glands
-Apocrine sweat glands
So, the answer is, “Apocrine.”
Note: - The ciliary glands in the eyelids include the modified apocrine glands; the ceruminous glands that manufacture ear wax; and the milk-producing mammary glands.
- Eccrine sweat glands cover the majority of the body.
- Eccrine glands on their paws increase friction when escaping from danger and keep them from slipping.
- The apocrine sweat glands are inactive before puberty; hormonal changes in puberty cause the glands to grow in size and begin to work. The secreted material is thicker than eccrine sweat and provides nutrients on the skin for bacteria: the sweat decomposition of the bacteria is what causes the acrid odor. In times of tension and sexual arousal, the Apocrine sweat glands are most involved.
- Apocrine sweat produces pheromone-like compounds in mammals (including humans) to attract other organisms within their species. The human sweat research showed variations in apocrine secretions and bacteria between men and women.
