Jan 28, 2024 · The meaning of SWEAT GLAND is a simple tubular gland of the skin that excretes perspiration, is widely distributed in nearly all parts of the human skin, and consists typically of an epithelial tube extending spirally from a minute pore on the surface of the skin into the dermis or subcutaneous tissues where it ends in a convoluted tuft.

Small tubular skin structures called sweat glands, also called sudoriparous or sudoriferous glands, are responsible for producing sweat. Exocrine glands are found all over the surface of the body and are responsible for sweat production. The integument’s appendages are the sweat glands. There are apocrine and eccrine sweat glands. They vary in dist...
Typically, sweat glands consist of a secretory unit found in the subcutaneous tissue or deep dermis and a duct that extends from the secretory unit to the body surface through which sweat or other secretory products are delivered. The gland is entirely encircled by adipose tissue, and the secretory coil or base is deeply embedded in the lower dermi...
Eccrine
There are eccrine sweat glands throughout the body, except few places such as ear canal, lips, etc. They are ten times less smaller than apocrine sweat glands, do not penetrate the dermis as profoundly, and secrete directly onto the skin’s surface. Sweat, often known as sensible perspiration, is the transparent secretion generated by eccrine sweat glands. Since sweat is derived from blood plasma, it primarily contains water and some electrolytes. Sweat has a salty taste because it contains so...
Apocrine
Apocrine glands produce sweat into the hair follicle’s pilary canal rather than directly onto the skin’s surface. There are apocrine sweat glands in the armpit, areola, perineum, ear, and eyelids. Compared to eccrine glands, the secretory area is more significant. The apocrine sweat glands are dormant before puberty; hormonal changes during puberty lead the glands to enlarge and start functioning. Thicker than eccrine sweat, the produced component feeds the bacteria living on the skin.
Apoeccrine
Some human sweat glands, known as apoeccrine glands, exhibit traits that make them difficult to identify as either eccrine or apocrine. They are smaller than apocrine but larger than eccrine glands. Their secretory component has a large segment, like apocrine glands, and a narrow section resembling secretory coils in eccrine glands. Apoeccrine glands are essential in axillary sweating because they secrete more sweat than eccrine and apocrine glands combined. They consistently produce a thin,...
Jan 17, 2023 · Sweat glands, also known as sudoriferous glands, are distributed over most of the body surface. LEARNING OBJECTIVE. Classify eccrine and apocrine sweat glands. Key Takeaways. Key Points. Sweat glands are located deep within the skin and primarily regulate temperature.
sweat gland Any of the numerous small, tubular glands that are found in the skin of many mammals and that secrete sweat externally through pores to help regulate body temperature. In humans and some other mammals, sweat glands are distributed over most of the body surface.
Sweat glands are tubular structures located within the deeper dermal tissue that contain a rich network of capillaries and nerve fibers. The investigation of sweat gland innervation began simultaneously to the initial studies of cutaneous epidermal nociceptive C-fibers using skin biopsies [1].
