Integumentary System Key Terms​- Derm/o- skin Derm/a - skin Kerat/o- hard, horn-shaped tissue; cornea Xer/o- dry Xanth/o - yellow Erythr/o - red Pedicu/o- louse(singular) , lice (singular) Onych/o - nail Myc/o - fungus Pil/o - hair; hair follicle Lip/o - fat Albin/o - white Rhytid- wrinkle Functions​- The Integumentary system consists of hair, skin, and nails. Its main function is to act as a barrier to protect the body from the outside world. Functions of the Skin- Protection- covers body and acts as a physical barrier Body temperature maintenance - perspiration (regulate body internal temperature) Excretion - during perspiration sweat glands flush small amounts of waste products Perception of stimuli - skin contains a large number of nerve endings and receptors that detect stimuli related to temperature, touch, pressure, and pain

Vocabulary-​ 1.)Gland- cell, or a group of cells that secretes select substances within or out of the body 2.)S​ ebaceous glands - located in the dermal layer of the skin over the entire body except palms and soles. Sebaceous glands secrete an oily substance called sebum, which contains lipids. 3.) Epidermis- forms the outermost layer of skin and is made up of keratin ( a fibrous water repellent protein). 4.) Dermis lies directly below the epidermis. The dermis is made up of connective tissue, blood and lymphatic tissue, nerve fibers, fair follicles, and sebaceous and sweat glands. 5.) Collagen- a fibrous protein found in skin, bone, cartilage, and tendons. 6.) subcutaneous layer - is the deepest layer of the skin and below the dermis. This layer connects the skin to surface muscles. 7.) Lipid- a group of organic compounds that consists of fat, are greasy to touch, and are insoluble. Lipids liberate the skin and minimize water loss. 8.) Melanin- is responsible for the skin pigmentation or color. 9.)Hair follicles - are tiny secretory cavities where hair grows. 10.) Basal layer - makes up the deepest layer of the epidermis. The layer is constantly growing and multiplying, with younger cells pushing old cells to the surface. Careers Oncologist​-​ A​ n oncologist a medical practitioner qualified to diagnose and treat tumors. An oncologist often treats skin cancer like melanoma and basal cell cancer.

Skeletal muscle can be contracted or relaxed through conscious control. Cardiac muscle -​ ​ is also called myocardial muscle and is found only around the heart. Like smooth muscle, cardiac muscle is unconsciously controlled. Tendons ​-​ connect muscles to bones. Disease/disorder-​ Ankylosis-​ a stiff joint caused by adhesion, or abnormal fusion of two bones into one Kyphosis- abnormal, outward curvature of the thoracic spine, humpback Osteosarcoma​- malignant tumor that arises from connective tissue and affects the bone.
