Skin Glands: Sebaceous, Eccrine, and Apocrine Glands
The human skin has several types of exocrine glands (Latin, glandulae cutis), which release their biochemical products onto the skin surface. All skin glands consist by a secretory compartment, the gland or coil (tubulus), and an excretory part, the duct (ductus).
Chapter 79. Biology of Sebaceous Glands - McGraw Hill Medical
Sebaceous glands are composed of lipid-producing sebocytes and of keratinocytes that line the sebaceous ducts and are usually associated with a hair follicle. The periphery of the sebaceous gland is a basal cell layer composed of small, cuboidal, nucleated, highly mitotic sebocytes.
Chapter 85. Disorders of the Apocrine Sweat Glands
Apocrine glands are composed of three components: (1) the intraepithelial duct, (2) the intradermal duct, and (3) a coiled gland in the deep dermis or at the junction of the dermis and subcutaneous fat, which contains the secretory portion.
Chapter 1: Structure and Functions of the Skin - McGraw Hill Medical
The skin is the site of many complex and dynamic processes as demonstrated in Figure 1-1 and Table 1-1. These processes include barrier and immunologic functions, melanin production, vitamin D synthesis, sensation, temperature regulation, protection from trauma and aesthetics.
Chapter 84. Disorders of the Eccrine Sweat Glands and Sweating
Abnormalities of eccrine sweat formation by the secretory coil and sweat ductal cells may occur or ductal disruption or occlusion may develop, preventing delivery of sweat to the skin surface. A review of the normal anatomy and physiology of eccrine sweat glands and sweating may be …
Chapter 83. Biology of Eccrine and Apocrine Glands
In humans, sweat glands generally are found as two types, (1) eccrine and (2) apocrine. Eccrine-gland sweat allows the body to control its internal temperature in response to thermal stress. Apocrine gland function is more obscure but likely includes pheromone production.

5 天之前 · Pearly penile papules Pink (skin-colored), 1- to 2-mm papules are seen regularly spaced along the corona of the glans penis. These structures, which are part of the normal anatomy of the glans, are commonly mistaken for condylomata or molluscum contagiosum.

Disorders of Sebaceous, Eccrine, and Apocrine Glands
5 天之前 · Follicular plugging (comedone) prevents drainage of sebum; androgens (quantitatively and qualitatively normal in serum) stimulate sebaceous glands to produce more sebum. Bacterial ( C. acnes ) lipase converts lipids to fatty acids and produces proinflammatory mediators (IL-I, TNF-α), which lead to an inflammatory response.

5 天之前 · BIG PICTURE. The functional component of the breast is the mammary gland, which synthesizes, secretes, and delivers milk to the newborn. It is only during a pregnancy that the mammary glands reach a mature state of development by way of circulating female hormones.
