Cells which are classified as apocrine bud their secretions off through the plasma membrane producing membrane bound vesicles in the lumen anatomy lumen . This method is also called decapitation secretion . The apical portion of the secretory cell of the gland pinches off and enters the lumen. Apocrine secretion is less damaging to the gland than holocrine secretion which destroys a cell but more damaging than merocrine secretion exocytosis . Apocrine sweat gland s are not true apocrine glands it is now known that they use merocrine secretion. The name is maintained for historical reasons. An example of true apocrine glands are mammary glands, responsible for secreting breast milk. ref Mescher AL, Chapter 4. Epithelial Tissue Chapter .

The preputial mucosa of the penis is the epithelium of the inside of the prepuce , or foreskin . To differentiate it from the cutaneous skin of the outside of the prepuce , it is sometimes referred to as the inner mucosa . 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 . The first four substances have protective immunological functions. fact date April 2007 A histology histological study Taylor 1996 , however, reported that the prepuce contains no apocrine glands apocrine sweat glands sweat glands whatsoever.

Exocrine secretion Merge from Holocrine glands date September 2011 Holocrine is a term used to classify the mode of secretion in exocrine gland s in the study of histology . Holocrine secretions are produced in the cytoplasm of the cell and released by the rupture of the plasma membrane , which destroys the cell and results in the secretion of the product into the Lumen anatomy lumen . Holocrine secretion is the most damaging type of secretion, with merocrine secretion being the least damaging and apocrine secretion falling in between. Examples of holocrine glands include the sebaceous glands of the skin and the meibomian glands of the eyelid . The sebaceous gland is an example of a holocrine gland because its product of secretion sebum is released with remnants of dead cells.

Easy to spot in areas with high deer populations, hunter s use them to find ideal locations for hunting. They appear in the late summer or early fall, when male deer rub the velvet off their newly acquired antler growth or during rut season. The area between the forehead and antlers contains a large number of apocrine sweat glands , and leave a scent that communicates a challenge to other male deer while also attracting potential mates.

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. The glands of Moll are named after Dutch oculist Jacob Anton Moll 1832 1914 . Gland of Moll 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.
