Section of Skin Showing Hairs and Sebaceous Glands
Section of the skin showing the hairs and sebaceous glands. The sebaceous glands are small saccular glands, the ducts of which open into the hair follicles. They are lined with epithelium and secrete a fatty, oily substance which they discharge into the hair follicles to lubricate the hairs and make them glossy. It also exudes over the surface of the skin to keep it soft and flexible. Labels: a, the epidermis; b, corium; c, muscles, attached to hair follicles and to under surface of epidermis.
