Eccrine/merocrine Sweat Glands The secretory parts are lined by simple cuboidal epithelium. The ducts are lined by stratified (2 layers) cuboidal epithelium. Long thin myoepithelial cells are arranged helically around the periphery between the secretory cells and their basement membrane.

There are more than 20 lymph nodes (small lumps of tissue that are part of the body's lymphatic system, which helps fight infection) in the armpit. These lymph nodes normally cannot be felt through the skin. The armpits have a high concentration of hair follicles and sweat glands.

Sweat glands occur all over the body, but are most numerous on the forehead, the armpits, the palms and the soles of the feet. Sweat is mainly water, but it also contains some salts. Its main function is to control body temperature. As the water in the sweat evaporates, the surface of the skin cools.

Sebaceous glands are found throughout all areas of the skin, except the palms of the hands and soles of the feet. There are two types of sebaceous gland, those connected to hair follicles and those that exist independently. Sebaceous glands are found in hair-covered areas, where they are connected to hair follicles.

Disorders of eccrine sweating can occur for many different reasons, including dysfunction of the thermoregulatory centers in the brain's central autonomic network, changes in the spinal sympathetic preganglionic, ganglionic, or postganglionic neurons/axons or in the muscarinic (M3) cholinergic synapse on sweat glands.
