Nov 3, 2023 · Basic structure. In general, sweat glands tend to comprise a secretory unit which is located either in the deep dermis or in the subcutaneous tissue, and a duct which continues from the secretory unit towards the body surface, through which sweat or secretory product is passed.

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:
- glandula sudorifera
- Ectoderm
- Eccrine: cholinergic sympathetic nerves, Apocrine: adrenergic nerves
- Integumentary
Jul 17, 2019 · The function of the myoepithelial cells is provision of structural support for the gland against the hydrostatic pressure generated during sweat production . The duct has two cell layers: basal and luminal cells. Its primary function is reabsorption of Na and Cl ions as sweat flows through the duct, as shown in Figure 2(d).

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 body, most numerously on the soles of the feet.

5 days ago · The meaning of SWEAT DUCT is the part of a sweat gland which extends through the dermis to the surface of the skin.
Apr 24, 2023 · Eccrine sweat glands allow for temperature control. When body temperature rises during physical activity, increased ambient temperature, or fever, these glands respond by secreting sweat. This sweat is eventually evaporated from the surface of the skin, effectively cooling down body temperature.
Before the sweat is released onto the skin surface, the fluid in the ductal lumen gains acidity, due to possible secretion of hydrogen ions into the sweat duct. The initial pH of sweat is about 7.1-7.4. Bicarbonate reabsorption is inversely related to sweat rate. Thus, at low sweat rates, the luminal fluid is exposed to the duct for a long time ...
