Skin sebaceous Glands are classified under the pilosebaceous unit and contain both a hair follicle and a hair. The glands are located everywhere in the body expect in the palms, soles, top of the feet, and the lower lip. The glands are heavily located on the face, upper neck and the chest. The glands produce sebum which is responsible for keeping the skin moisturized. The major function of the sebaceous glands is secretion of the sebum by a holocrine process. The sebum secreted is composed of triglycerides, wax esters and squalence. Sebum on the skin plays a crucial role in maintain a skin barrier by expressing pro inflammatory and anti inflammatory properties. Combination of sebum and other apocrine secretions have a thermoregulatory role (Smith, 2011). Sweat glands are tube like structures located within the skin, in which sweat is produced and then transported to the surface of the skin. The sweat glands are classified into Eccrine and apocrine sweat gland. Every sweat gland contains a hollow tube, which is long and coiled like a ball at its base. The coiled part is usually located in the dermis. The duct allows sweat to move from the base towards the surface of the skin. The duct has a pore on the skin surface. There are three major functions of the sweat glands which are thermoregulation, excretion, and protection. In the thermoregulation, sweat cools the surface of the skin and reduces body temperature. During excretion the glands will provide a significant excretory route for both water and electrolyte. In protection, the glands help in preserving the skin’s acid mantle which contributes to skin protection form bacteria and other pathogenic organisms. Hair is a skin structure that has a follicle and a shaft. The hair shaft is...
