Integrated Science Name ___KEY___________________________ Skeleton, Muscles, Skin, Heart Quiz – Study Guide KEY Define (Matching Column) Tendon Connects muscle to bone Artery away from heart Ligament Connects bone to bone Vein To the heart Epidermis Top layer of skin, mostly dead cells Melanin color cell in epidermis Dermis Bottom layer of skin, “good” stuff Voluntary/Striated skeletal; can control Cardiac Muscle Heart muscle, unique Involuntary/Smooth smooth; no control Vitamin D Needed for calcium absorption Sweat gland Your dermis has 3 million Periosteum Covers around bones Joint where 2 bones meet Cartilage Covers ends of bones, cushions Integumentary Skin, hair, nails Skeleton/Bones 1. Know the 5 functions of the skeletal system. Shape and support; protect organs; place for muscles to attach; Store Calcium and Phosphorus; Make red blood cells (in marrow) 2. Name 4 types of moveable joints (give examples of each) a. Hinge (knee, fingers, elbow) b. Gliding (wrist, vertebrae, ankle) c. d. pivot (neck) Ball and Socket (shoulder, hip) 3. How many bones are in an adult? 206 4. Why are tendons stiff and ligaments flexible? Tendons must pull the bone; ligaments must stretch with joint movement Muscles 5. What determines the direction of motion of bones? Type of JOINT 6. What are the three types of muscles? Which is striated? Smooth? Voluntary (striated) and involuntary (smooth), and cardiac 7. Identify (examples?) where each type of muscle is found. Voluntary: skeletal muscles; Involuntary (smooth) = hollow organs (stomach, intestines, etc); cardiac = heart 8. Muscles get _short? or long?_ when contracted. 9. Why do muscles work in pairs? Muscles can only PULL in one direction, they need another muscle to pull in the opposite direction Heart and Circulation 10.

The largest artery in your body is the ___aorta__. 15. What determines the direction of blood flow? Valves (in heart or blood vessels) Skin 16. What THREE things are found in sweat? Water, salt, urea 17. What are FIVE functions of the skin? Protection; contain sensory nerves, make vitamin D, regulate body temperature, and excrete wastes 18. What is the largest organ of your body? The SKIN 19. How and where does your body make Vitamin D? in the epidermis in Sunlight 20. Why do people with severe burns die? They lose body fluids, dehydrate, and die 21. The thickest human skin is __2.5_ mm thick found on your _foot soles_. 22. What is the most serious type of skin caner? melanoma Trivia/Bonus Q’s How many times does your heart beat in your lifetime? 2.5 billion Which animal has the thickest skin?
