According to mode of secretion there are three types of exocrine glands in body: Merocrine glands : secretion occurs as vesicles, no part of cell is shed. Apocrine glands : a portion of cell is shed with secretion. Holocrine glands : secretion occurs by whole cell being ruptured.
What is the function of the apocrine sweat glands?
Your treatment options include:
- Botox. Botulinum toxin A (Botox), which works by blocking nerve impulses to the muscles, can be injected into the underarm to block nerve impulses to the sweat glands.
- Liposuction. One way to cut down on apocrine sweat is to remove the sweat glands themselves.
- Surgery.
- Home remedies.
What are the different types of exocrine glands?
- Prolactin: Stimulates milk production in mothers.
- Somatotropin: A hormone that regulates the growth of the body and tissues.
- Luteinizing hormone: Stimulates ovulation (egg formation) in females and testosterone production in males.
- Thyroid-stimulating hormone: Stimulates the thyroid gland to produce T3 & T4 hormones.
What are some examples of exocrine glands?
Examples: mammary gland, sweat gland, lips, skin around anus, pubic region, and nipples. Characteristics of Exocrine Glands: Substances secreted from the exocrine glands respond very quickly and they are conveyed through ducts and released accurately at the target area for specific functions.
What are the functional classification of exocrine glands?
The three types of exocrine glands are:
- Holocrine Glands
- Merocrine Glands
- Apocrine Glands
What is the difference between merocrine apocrine and holocrine glands quizlet?
What is the difference between apocrine, holocrine and merocrine secretion? Merocrine secretion doesn't result in damage to the cell. With apocrine secretion, part of the cell breaks off and is released. Holocrine secretion destroys the whole cell.
How are merocrine apocrine & holocrine modes of secretion different?

Which is pinched off from the apical portion of the cell.
What is holocrine and apocrine?
Apocrine glands release their secretory products contained within membrane-bound vesicles. This type of secretion is rare and these glands are found in the breast and constitute some sweat glands. Holocrine glands release whole secretory cells, which later disintegrate to release the secretory products.
What are the 3 types of glands?
The exocrine glands are of three types:Holocrine Glands.Merocrine or Eccrine Glands.Apocrine Glands.
What are the three secretion methods of exocrine glands and how does each method work?
The three mechanisms by which exocrine glands release their secretions include merocrine, apocrine, and holocrine. Merocrine glands are the most common subtype. By definition, merocrine gland secretions exit the cell via exocytosis. In this method of secretion, there is no cell damage.
What do merocrine glands and holocrine glands have in common?

For use in the body most glands are made up of epithelial tissue and their seat creations include mucin hormones
How do holocrine glands release their secretions?
Holocrine glands release their secretions when cells burst. What is this process called? Merocrine glands release their secretions when vesicles containing secretions bind with the plasma membrane.
How do holocrine glands secrete?
Holocrine secretions are produced in the cytoplasm of the cell and released by the rupture of the plasma membrane, which destroys the cell and results in the secretion of the product into the lumen.
How do merocrine glands secrete?
Merocrine glands secrete product through exocytosis of secretory vacuoles. No part of cell is lost in the process. Apical regions (=away from basement membrane side) of cells in apocrine glands get pinched off as secretion, thus cells partially lose cytoplasm during secretion.
Which glands secrete products in the duct system?
Exocrine glands secrete their products in duct system as happens in case of enzymes, milk, sebum or sweat. 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.
What is the difference between apocrine and merocrine sweat 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 are merocrine glands located?
They are simple tubular exocrine glands that secrete sweat to the surface of the skin directly. They are found in the superficial hypodermis. Therefore, they do not extend to the dermis of the skin.
What are the functions of merocrine sweat glands?
Merocrine sweat glands carry out several important functions in the human body. They are thermoregulation, protection and excretion.
How do sweat glands work?
Hence, the cell loses a part of the cytoplasm. Sweat glands are sweat-producing small tubular exocrine glands. They can be merocrine (eccrine) or apocrine sweat ...
What are the two types of glands?
Glands are a type of organs that secretes substances in the body. There are two main types of glands as endocrine glands and exocrine glands . Exocrine glands secrete their products into a duct. Multicellular exocrine glands can be classified further into different types based on the secretion method.
Which sweat gland contains nutrients for the bacteria present on the skin?
Figure 02: Apocrine Sweat Gland. Secretion of apocrine sweat glands is thicker than the sweat produced by the merocrine sweat glands. Moreover, it contains nutrients for the bacteria present on the skin. When these bacteria decompose nutrients in the sweat, it gives a characteristic odour.
Which sweat glands secrete sweat into the hair follicle?
Compared to merocrine sweat glands, apocrine sweat glands are larger and have a large secretory portion. Apocrine sweat glands secrete sweat into the pilary canal of the hair follicle without opening directly onto the surface of the skin. Figure 02: Apocrine Sweat Gland.
What is Apocrine Sweat Gland?
An apocrine sweat gland is a type of gland that is associated with a hair follicle and that produces a type of sweat that tends to have an odor.
What is Merocrine Sweat Gland?
These glands occur throughout the body but are more concentrated on the palms of the hand and soles of the feet.
Difference between Apocrine and Merocrine sweat glands
An apocrine sweat gland is a sweat gland associated with hair and found in only certain parts of the body. A merocrine sweat gland is a type of gland that is found throughout the body.
