Allergology international : official journal of the Japanese Society of Allergology. Apocrine sweat glands start to function at puberty under the stimulation of sex hormones. Eccrine sweat glands secrete a salty solution (sweat), which reaches the skin pores via an eccrine duct. They are also called sudoriferous glands. These glands are found all over the skin’s surface, but are especially abundant on the palms of the hand, the soles of the feet, and the forehead (Figure 4). Desmosomes are sparse but they are ob- served occasionally joining the myoepithefium to the secretory cells (Fig. When the internal temperature of the body rises, sweat glands release water to the skin surface. Structure of the Eccrine Sweat Gland The eccrine sweat gland consists of a simple tubular epithelium, and is comprised of the reabsorptive sweat duct (RSD) and the secretory coil. Also, both are exocrine glands made up of small, tubular structures. The duct of the gland is opened at the skin surface by minute pore. These glands are composed by of intra-epidermal spiral duct, which is a dermal duct that contains two portions; a straight and coiled portion.

Here we compared the multilayered epithelia formed by epidermal keratinocytes and those formed by eccrine sweat gland cells. These apocrine glands empty into the hair follicle (epitrichial glands) or onto the skin surface (eccrine glands). Sweat glands are found in the superficial hypodermis near the border of the dermis. In the eccrine sweat glands myoepithelial cells … The secretory coils of glutaraldehyde-osmium tetroxide-fixed and Epon-Araldite-embedded eccrine sweat glands from the palms of young men were studied with the electron microscope. Eccrine carcinoma (EC) is a rare carcinoma that originates from the eccrine sweat glands of the skin and accounts for less than 0.01% of diagnosed cutaneous malignancies. Interconnections between these plexuses form via connecting vessels that run perpendicular to the skin surface, creating a continuous vascular plexus in the skin. The ducts spiral to the surface of the epidermis to release sweat. The other, apocrine glands, develop around hair follicles [source: Britannica]. The structure of the glands of the skin. The other kind is the eccrine sweat gland which secretes sweat directly onto the surface of the skin. They consist of two portions - a secretory portion and excretory duct portion. Douglas L.

[17], Hypohydrotic ectodermal dysplasia is a disease characterized by hypotrichosis (decreased growth of scalp and body hair), hypodontia (congenital absence of teeth), and hypohidrosis. Sweat gland tumors have traditionally subdivided into four broad groups: eccrine, apocrine, mixed origin (eccrine and apocrine) and other un-classifiable sweat gland tumors. eccrine gland: The major sweat glands of the human body, found in virtually all skin, produce a clear, odorless substance, consisting primarily of water and NaCl. Eccrine sweat glands receive sympathetic innervation via cholinergic fibers that send impulses in response to changes in core body temperature. Eccrine glands secrete via merocrine secretion, in which secretion is by exocytosis, and secrete directly onto the surface of the skin. The secretory gland is coiled and consists of of secretory, epithelial cells and an outer layer of myoepithelial cells that are contractile. Both the dermal and epidermal segment of the eccrine as well as apocrine ducts consist of two epithelial layers: luminal cells and peripheral cells. 149,589,031 stock photos online.
