Eccrine sweat glands

Eccrine sweat glands are a type of sweat gland that are found in almost all regions of the human skin. They are responsible for the production of sweat, which helps regulate body temperature.

Function

Eccrine sweat glands are responsible for the production of sweat, a liquid composed of water, salt, and other minerals. This sweat is released onto the surface of the skin, where it evaporates and cools the body. This process is crucial for maintaining a stable internal body temperature, especially during physical activity or in hot environments.

Structure

Eccrine sweat glands are tubular structures that are embedded in the dermis and hypodermis layers of the skin. They consist of a secretory portion located in the dermis, which produces sweat, and a duct that carries the sweat to the skin's surface. The secretory portion is surrounded by myoepithelial cells, which contract to expel the sweat.

Distribution

Eccrine sweat glands are found all over the human body, but they are most densely packed on the palms of the hands, soles of the feet, and forehead. They are less common on the trunk and extremities.

Clinical significance

Abnormal function of the eccrine sweat glands can lead to a variety of conditions, including hyperhidrosis (excessive sweating), anhidrosis (inability to sweat normally), and miliaria (heat rash). These conditions can be caused by genetic factors, underlying medical conditions, or certain medications.
