Epidermis: Thin outer layer of the skin
Dermis: Layer that sits on the hypodermis and supports the epidermis Keratin: A protein that flattens, hardens, and makes the skin water resistant Subcutaneous Layer: A layer of insulation
Epidermis: Contains the stratum germinativum and stratum corneum

Eccrine: Gland that play a crucial role in body temperature regulation Ceruminous: Modified sweat glands that secrete ear wax
Mammary: Modified sweat glands that secrete milk
Melanin: Tanning pigment
Cyanosis: Condition in which the skin has a bluish tint because of poor oxygenation Jaundice: Yellowing of the skin because of bilirubin pigmentation Vitiligo: Patches of white skin due to loss of pigmentation

c. Answer the following questions about the Integumentary system.
1. Mention and explain extensively the major function of the Integumentary system. If it is uncomplicated for you answer this question as an essay (none less than 5 paragraphs.) The Integumentary System, consisting of the skin, hair and nails, act as a barrier to protect the body from the outside world. It also has several other functions in the body. The word INTEGUMENT comes from a Latin word that means to cover. The most important function of the integumentary system is protection. This system serves as a barrier against infection and injury, helps to regulate and maintain body temperature, removes waste products from the body, and provides protection against the sun's ultraviolet radiation. The skin is a protective covering, also the largest organ in our body. It is composed of an epidermis and a dermis separated by a basement membrane. A subcutaneous layer, not part of the skin, lies beneath the dermis. The skin houses several different types of glands such as...
