Where are merocrine glands the most concentrated?
Where are merocrine glands the most concentrated?
The merocrine glands are widespread and found in the skin throughout the body with the highest concentrations in some areas such as the soles of the feet. The glands are located in the dermis and hypodermis of the skin, and unlike the apocrine sweat glands are not associated with hair follicles.
What is an example of a Merocrine gland?
Merocrine glands are the most common subtype. By definition, merocrine gland secretions exit the cell via exocytosis. An example of merocrine secretion is the eccrine sweat gland. Apocrine glands, in contrast, form buds of the membrane which break off into the duct, losing part of the cellular membrane in the process.
What are apocrine glands and their location?
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 merocrine 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.
Are salivary glands merocrine?
The salivary gland possesses tubuloacinar units, and these are merocrine. The functional unit of the salivary glands is the terminal secretory piece called acini with a roughly spherical or tubular shape.
What is a merocrine gland in anatomy?
n. A gland whose secretory cells produce a secretion but are not destroyed or damaged during the process.
Where are the eccrine and apocrine glands located?
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.
Which is merocrine gland from the following *?
Complete Step by Step Answer: ‘Salivary gland’ is a type of merocrine gland as its secretion i.e. saliva is secreted into the buccal cavity by exocytosis. It does not cause any damage or degeneration of its constituent cells. Some other merocrine glands are the sweat gland and pancreatic gland.
Are merocrine glands endocrine?
This is different from the mode of secretion seen in ductless endocrine glands, which release their products (mainly hormones) directly in blood stream. Merocrine glands secrete product through exocytosis of secretory vacuoles. No part of cell is lost in the process.
Which parts are found in the dermis?
The dermis houses blood vessels, nerve endings, hair follicles, and glands. There are many cell types found within the connective tissue of the dermis, including fibroblasts, macrophages, adipocytes, mast cells, Schwann cells, and stem cells.
