skin Scientific  

/ skĭn /

1. The outer covering of a vertebrate animal, consisting of two layers of cells, a thick inner layer (the dermis) and a thin outer layer (the epidermis). Structures such as hair, scales, or feathers are contained in the skin, as are fat cells, sweat glands, and sensory receptors. Skin provides a protective barrier against disease-causing microorganisms and against the sun's ultraviolet rays. In warm-blooded animals, it aids in temperature regulation, as by insulating against the cold.

skin Cultural  

1. The external tissue that covers the body. As the body's largest organ (it makes up about one twenty-fifth of an adult's weight), the skin serves as a waterproof covering that helps keep out pathogens and protects against temperature extremes and sunlight. The skin also contains special nerve endings that respond to touch, pressure, heat, and cold. The skin has an outer layer, or epidermis, and a layer immediately below, called the dermis.

Etymology

Origin of skin

First recorded in 1050–1100; Middle English noun skin, skin(n)e, Old English scinn, from Old Norse skinn “skin, fur”; cognate with dialectal German Schinde “rind, skin of fruit”; the verb was derived from the noun

Explanation

Our bodies are covered with skin, a layer of tissue that's also humans' largest organ. When you are sick and have a fever, your skin feels warm. Skin is something we have in common with other vertebrates. The peels of some fruits and vegetables are sometimes called skin too. As a verb, skin means to remove a peel or skin, or to scrape your skin: "If you skateboard in shorts, you're going to skin your knee." If you do something "by the skin of your teeth," you just barely manage it. Skin comes from the Old Norse word skinn, "animal hide."
