Image Apocrine.jpg thumb 300px Apocrine gland Exocrine secretion Apocrine is a term used to classify exocrine glands in the study of histology . Cells which are classified as apocrine bud their secretions off through the plasma membrane producing membrane bound vesicles in the Lumen anatomy lumen . Apocrine glands are a type of exocrine gland that are present in areas such as the axillae armpits , areola , in the perineum genital areas , around the belly button and in the external auditory canal as wax secreting glands . Specialized types of apocrine glands present on the eyelids are called Moll s glands . Apocrine sweat glands are inactive until they are stimulated by hormonal changes in puberty. Apocrine glands secrete a milky, viscous odourless fluid which only develops a strong odour when it comes into contact with bacteria on the skin surface. Apocrine glands secrete this fluid by a method called decapitation secretion . The apical portion of the secretory cell of the gland pinches off and enters the lumen of the gland. In contrast to this mechanism of secretion, Eccrine glands secrete by a method called merocrine secretion and sebaceous glands secrete by a method called holocrine secretion. Apocrine sweat glands are mainly thought to function as olfactory pheromones , chemicals important in attracting a potential mate.

It starts at the ridged band of the prepuce and continues to the coronal sulcus groove behind the glans penis , where it meets the epithelium of the glans and penile shaft. The preputial mucosa is devoid of hair, as is the cutaneous surface. The preputial mucosa contains fewer Langerhans cell s than most mucosal epithelia Weiss 1993 . These cells secrete cytokine s a non antibody protein that generates an immune response on contact with specific antigens , and are an essential part of the immune system . According to one review Fleiss 1998 , the inner mucosa contains apocrine glands , which secrete cathepsin B , lysozyme , chymotrypsin , neutrophil elastase , and hormones such as androsterone .

Glands of Moll , also known as ciliary glands , are modified apocrine sweat glands that are found on the margin of the eyelid . They are next to the base of the eyelash es, and anterior to the Meibomian glands within the distal eyelid margin. These glands are relatively large and tubular shaped. Moll s glands empty into the adjacent lashes. Glands of Moll and Glands of Zeis Zeis secrete lipid that adds to the superficial layer of the Tears tear film , retarding evaporation. The glands of Moll are prone to infection and blockage of its duct with sebum and cell debris. Blockage of the gland s duct causes swelling which can manifest itself as a stye . The glands of Moll are named after Dutch oculist Jacob Anton Moll 1832 1914 .
