Where is merocrine sweat gland?
Location: 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 the difference between merocrine and apocrine 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.
What is the difference between eccrine and merocrine sweat glands?
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 glands are merocrine glands?
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.
What is holocrine apocrine and merocrine glands?
Merocrine glands, such as salivary gland s, pancreatic glands, and eccrine sweat gland s, are comprised of secretory cells that excrete products through exocytosis. Holocrine gland. Holocrine gland is a gland releasing a secretion consisting of disintegrated cell s and their secretory products into the lumen .
What does the merocrine gland secrete?
The ducts open out onto epidermal ridges at a sweat pore. They can be further classified as merocrine (eccrine) glands. They secrete a watery fluid which is hypotonic to plasma its evaporation is important for thermoregulation. Sweat contains water, sodium, potassium, chloride, urea ammonia and lactic acid.

What is the difference between eccrine and apocrine glands?
Definition: 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 the function of sweat glands?
The primary function of sweat glands is to keep the core body temperature at approximately 37 °C by releasing sweat in a hot environment or during physical activity [189,195]. Sweat glands are innervated by neurons, so the process of sweating is controlled by the central nervous system.
