Arrector pili muscles are composed of mesodermal smooth muscle, and are also found in the dermis. To the left of the gland is the thin slip of arrector pili muscle. [4] Air becomes trapped between the erect hairs, helping the animal retain heat. Keratin provides a tough protective layer for the epidermis. skin nerves, thermoregulation physiology, sensory nerves function, what is epidermis, functions of the skin, what is dermis, human skin anatomy, The ABCD rule describes the appearance of the most serious form of skin cancer, melanoma. (True/False), Sebaceous glands may be classified as eccrine or apocrine depending on their locations.
