3 Νοε 2023 · Exocrine glands that produce sweat, located within the dermis/subcutis of the skin. Simple coiled glands whose watery excretion aids thermoregulation by evaporating from the body surface, thus cooling the body. Simple tubular glands whose excretion contributes to body odor.
Each eccrine gland is a single tubular structure, about 3–5 mm in length in humans with a secretory coil below a relatively straight sweat duct (Fig. 1) (17). The secretory coil contains three types of cells – dark, clear and myoepithelial – identifiable by conventional microscopy in humans.
27 Μαΐ 2015 · Derived from embryonic ectoderm, millions of eccrine glands are distributed across human skin and secrete litres of sweat per day. Their easy accessibility has facilitated the start of analyses of their development and function.
Eccrine glands are active in thermoregulation by providing cooling from water evaporation of sweat secreted by the glands on the body surface and emotionally induced sweating (anxiety, fear, stress, and pain).
Eccrine sweat glands localize to the dermis and upper region of the hypodermis. The secretory gland is coiled and consists of of secretory, epithelial cells and an outer layer of myoepithelial cells that are contractile. The secretory cells are a mix of light and dark staining cells.
The less versatile eccrine sweat glands serve principally in reducing body temperature by the production and surface evaporation of sweat; in moistening and lubricating the epidermis especially where it is greatly thickened; and in formation of sweat in response to emotional stimuli.
24 Απρ 2023 · Eccrine is the most common of the sweat glands, distributed all over the body except the lips and part of the external genitalia. Apocrine glands are limited to the axilla, areola, nipple, skin around the anus, and external genitalia and have an odor.
