Skin appendage

Skin Appendage: Glands

The skin appendage glands are an integral part of the integumentary system, which includes the skin and its appendages. The primary function of these glands is to secrete substances that aid in the body's overall function and protection. The two main types of glands found in the skin are sweat glands and sebaceous glands.

Etymology

The term "appendage" originates from the Latin word 'appendere', meaning 'to hang something'. It refers to parts that are attached to the main body. The term "gland" comes from the Latin 'glandula', meaning 'small acorn', due to the shape of certain glands.

Sweat Glands

Sweat glands, also known as sudoriferous glands, are small tubular structures situated within the skin, and extend towards the surface of the skin. They are responsible for the production and secretion of sweat, a fluid comprising primarily of water, along with various dissolved substances such as salts and sugars. This process, known as perspiration, aids in the regulation of body temperature and the elimination of certain wastes.

Sebaceous Glands

Sebaceous glands are microscopic exocrine glands in the skin that secrete an oily or waxy matter, called sebum, which lubricates and waterproofs the skin and hair of mammals. These glands are usually associated with hair follicles but can also be found in hairless areas of the skin.
