Basic Structure of the Skin : Part 3

January 04, 2021

This section is dedicated to learning about three specialized structures in the skin : eccrine glands, apocrine glands and sebaceous glands. 

Eccrine glands are located in the dermis.  They produce sweat and drain directly to the skin.  These glands are found throughout the skin from head to toe with a higher concentration on the palms and soles.  The sweat produced has no odor and composed mostly of water.

Apocrine glands are also located in the dermis but secrete into the pores where hair follicles are found. The sweat produced by apocrine glands is a bit different in that it is oily and can have an odor once bacteria acts on it.  These glands are located in specific areas such as the underarms, eyelids, nipples, ears, perianal area, outer edges of nose and external genitalia.  

Sebaceous glands secrete an oily wax like substance into the hair follicle to provide moisture and lubrication to the skin and hair.  These glands are found predominantly in the scalp, face, and upper torso.  There are some areas where they can concentrate such as the lips, nipples and groin.
