What are the Similarities Between Merocrine and Apocrine Sweat Glands?
- Merocrine and apocrine sweat glands are the two types of sweat glands found in the skin.
- Both produce clear, odourless sweat.
- They are exocrine glands which are multicellular.
What is merocrine gland?
Merocrine (or eccrine) is a term used to classify exocrine glands and their secretions in the study of histology. A cell is classified as merocrine if the secretions of that cell are excreted via exocytosis from secretory cells into an epithelial-walled duct or ducts and then onto a bodily surface or into the lumen.
What is the difference between merocrine and eccrine?
Merocrine. Merocrine is the most common manner of secretion. The gland releases its product and no part of the gland is lost or damaged (compare holocrine and apocrine ). The term eccrine is specifically used to designate merocrine secretions from sweat glands ( eccrine sweat glands ).
What are exocrine glands and where are they found?
Exocrine glands can be found in many different organs and have many different functions. Exocrine glands secrete sweat from your sweat glands, tears from your lacrimal glands, saliva from your salivary glands, milk from your mammary glands and more. What are exocrine glands?
What is the difference between holocrine and sudoriferous glands?
The sudoriferous glands are responsible for the excretion of the oils on the skin which helps to protect the skin from dryness. With the complexity of oils required, a holocrine gland is best suited to deliver them. Merocrine glands are scattered throughout the body and play an important role in temperature regulation, fluid balance, and digestion.
What is an example of a Merocrine gland?
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 is the function of the Merocrine gland?
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 all sweat glands merocrine?
Sweat glands are sweat-producing small tubular exocrine glands. They can be merocrine (eccrine) or apocrine sweat glands.
What is a merocrine gland in anatomy?
Merocrine (or eccrine) is a term used to classify exocrine glands and their secretions in the study of histology. A cell is classified as merocrine if the secretions of that cell are excreted via exocytosis from secretory cells into an epithelial-walled duct or ducts and then onto a bodily surface or into the lumen.
Are sweat glands merocrine or apocrine?
merocrineSebaceous glands are holocrine glands, and sweat glands (both eccrine and apocrine ones) are merocrine glands.
Is the pancreas a Merocrine gland?
Merocrine glands, such as salivary glands, pancreatic glands, and eccrine sweat glands, are comprised of secretory cells that excrete products through exocytosis (into the epithelial-walled ducts and then to lumen) without causing any damage or loss in the secretory cell.
Are merocrine glands endocrine?
There are two types of glands in the body. Endocrine glands are ductless and mainly produce hormones. Exocrine glands release their products through a duct. Merocrine and holocrine glands are types of exocrine glands.
What is the difference between merocrine apocrine and holocrine glands?

Do nipples have sweat glands?
In humans, apocrine sweat glands are found only in certain locations of the body: the axillae (armpits), areola and nipples of the breast, ear canal, eyelids, wings of the nostril, perineal region, and some parts of the external genitalia.
What is the merocrine secretion?
Definition of merocrine : producing a secretion that does not contain cellular components and is discharged without major damage to the secreting cell also : produced by a merocrine gland.
What is merocrine secretion quizlet?
Merocrine. Release fluid through exocytosis. Example: salivary glands. Apocrine. Lose small portions of their glandular cell bodies during secretion.
What is the function of apocrine sweat glands?
Apocrine glands produce viscous, lipid-rich sweat, which is also comprised of proteins, sugars, and ammonia [21,23]. The function of apocrine glands in many species is generally regarded as scent glands involved in production of pheromones (body odor), although this social/sexual function is rudimentary in humans.
What is the name of the gland that releases its product?
The gland releases its product and no part of the gland is lost or damaged (compare holocrine and apocrine ). 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 term for exocrine secretion?
Exocrine secretion. view. talk. edit. Merocrine or eccrine – by exocytosis. Apocrine – by membrane budding (loss of cytoplasm) Holocrine – by membrane rupture. Merocrine secretion. Merocrine (or eccrine) is a term used to classify exocrine glands and their secretions in the study of histology.
What is the most common way of secretion?
A cell is classified as merocrine if the secretions of that cell are excreted via exocytosis from secretory cells into an epithelial-walled duct or ducts and then onto a bodily surface or into the lumen . Merocrine is the most common manner of secretion.
