6.) The subcutaneous layer beneath the dermis consists of loose connective and adipose tissues. It contains the major blood vessels that supply the skin.
8.) The layers of the epidermis are Stratum coneum, Stratum Lucidum, Stratum granulosum, Stratum spinosum, and Stratum basale.
13.) Hair follicle is tubelike depression in the skin in which a hair develops. Hair develops from a group of epidermal cells at the base of the hair follicle.
15.) Nails are formed from skin cells. Special cells called epithelium form nails.
16.) The function of sebaceous glands contains groups of specialized epithelial cells and is usually associated with hair follicles.
22.) Radiation is one way of heat loss. It infrared heat rays escape from warmer surfaces to cooler surroundings. Another is Conduction. When heat moves from the body directly into the molecules of cooler objects in contact with its surface. The last one is to evaporation. When the body temperature rises above normal, The nervous system stimulates eccrine sweat glands to release sweat onto the surface of the skin.
25.) The Physiological Factors of the skin are Cyanosis, Carotene, and jaundice. Cyanosis is when the blood oxygen concentration is low, hemoglobin is dark red, and the skin appears bluish.

29.) Aging of skin is caused when the cell cycle slows, cells tend to grow larger and more irregular in shape. When you have liver spots its when sites of oxidation of fats in the secretory cells of apcrine and eccrine glands and reflect formation of oxygen free radicals. Also, when slowed melanin production causes hair to become gray or white as the follicle becomes a increasingly transparent.
