Eccrine sweat glands are found in virtually all skin, with the highest density in the palms of the hands, and soles of the feet, and on the head, but much less on the torso and the extremities. In other mammals, they are relatively sparse, being found mainly on hairless areas such as foot pads.

They are larger than eccrine glands, but smaller than apocrine glands. [38] Their secretory portion has a narrow portion similar to secretory coils in eccrine glands as well as a wide section reminiscent of apocrine glands. [39] Apoeccrine glands, found in the armpits and perianal region, have ducts opening onto the skin surface. [40]
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), [1] although the term merocrine is often used interchangeably. [2] [3]
Eccrine glands are the predominant sweat gland in the human body with numbers totaling up to 4 million. [3] They are located within the reticular dermal layer of the skin and distributed across nearly the entire surface of the body with the largest numbers occurring in the palms and soles. [4] [3] [5] Eccrine sweat is secreted in response to ...
If acne is occurring, it is because these gland ducts are blocked. Eccrine (merocrine) glands are most common. The secretions are very watery that contain some electrolytes; Apocrine glands produce a fatty secretion, thus giving away an odorous smell. These are located in the inguinal and axillary regions of the body, and include the mammary ...
The apocrine gland secretes an oily fluid with proteins and lipids that is odorless before microbial activity. It appears on the skin surface mixed with sebum, as sebaceous glands open into the same hair follicle. [23] Unlike eccrine sweat glands, which secrete continuously, the apocrine glands secrete in periodic spurts. [20]
Like sweat glands, eccrine glands allow excess water to leave the body. The majority of eccrine glands are located mainly on the forehead, the bottoms of the feet, and the palms, although the glands are everywhere throughout the body. They help the body to maintain temperature control. Eccrine glands in the skin are unique to mammals. [citation ...
