Sweat glands are a type of exocrine gland, which are glands that produce and secrete substances onto an epithelial surface by way of a duct. There are two main types of sweat glands that differ in their structure, function, secretory product, mechanism of excretion, anatomic distribution, and distribution across species:

Eccrine sweat glands are the most numerous, distributed across nearly the entire body surface area, and responsible for the highest volume of sweat excretion [5]. By contrast, apocrine and apoeccrine glands play a lesser role in overall sweat production as they are limited to specific regions of the body [7 – 10].

Nov 3, 2023 · There are two types of sweat glands: Eccrine glands are found all over the body and secrete a watery product that cools the skin. Apocrine sweat glands are mainly found in the armpits and perianal area, and secrete a more viscous, odorous product.

Oct 10, 2022 · Sweat glands are appendages of the integument. There are eccrine and apocrine sweat glands. They differ in embryology, distribution, and function. Eccrine sweat glands are simple, coiled, tubular glands present throughout the …

Jan 21, 2025 · A sweat gland is a specialized exocrine gland in the skin that produces and secretes sweat, primarily composed of water, salts, and waste products. Sweat glands are essential for regulating body temperature and excreting metabolic waste.

sweat gland, either of two types of secretory skin glands occurring only in mammals. The eccrine sweat gland, which is controlled by the sympathetic nervous system, regulates body temperature. When internal temperature rises, the eccrine glands secrete water to the skin surface, where heat is removed by evaporation.

Apr 24, 2023 · Sudoriferous glands, also known as sweat glands, are either of two types of secretory skin glands, eccrine or apocrine. Eccrine and apocrine glands reside within the dermis and consist of secretory cells and a central lumen into which material is secreted.

Mature glands have two secretory cell types, clear and dark cells, whose comparative development and functional interactions remain largely unknown. Clear cells have long been known as the major secretory cells, but recent studies suggest that dark cells are also indispensable for sweat secretion.

In sweat glands, multiple elongated myoepithelial cells synchronously contract their tubular secretory portions for excretion of sweat (upper panel), while stellate-shaped myoepithelial cells individually contract their acinar secretory portions of salivary and mammary glands (lower panel).

Feb 25, 2025 · Sweat Glands – Glands in the dermis that produce sweat for thermoregulation and waste removal. Tactile Cells (Merkel Cells) – Cells involved in touch sensation, located in the epidermis. Vascularization – The process of supplying blood to the skin via capillaries and larger blood vessels in the dermis.
