Krause corpuscles, mechanoreceptors. Free nerve endings around hair follicles. Ruffini corpuscles, stretching of skin. Pacianian corpuscles, pressure and vibrations. They help regulate body heat.
Eccrine glands are simple coiled glands .
Their secretory epithelium is usually simple cuboidal or columnar with two cell types being recognized. They are supplied by postganglionic sympathetic nerve fibers that are cholinergic. Dark cells and clear cells are the secretory cells. Dark cells produce a mucous-like secretion while clear cells make an aqueous secretion. The ducts are composed of stratified cuboidal epithelium, and these open onto the skin surface.
