1. Muscular & Integumentary Systems

2. What is this muscle called? a)Gluteus maximus b)Quadriceps c)Gastrocnemius d)Soleus

3. What is this muscle called? a)Pectoralis b)Deltoid c)Trapezius d)Triceps

4. What is this muscle called? a)Biceps b)Triceps c)Internal Obliques d)External Obliques

5. Functions of the Muscular System 1.Muscles are the motors that move body parts a)Muscles always pull, they never push

6. Functions of the Muscular System 1.Muscles are the motors that move body parts a)Muscles always pull, they never push b)Pairs of skeletal muscles work together: 1 muscle contracts while the other muscle relaxes

7. Functions of the Muscular System 2.Maintain homeostasis by keeping body temperature constant a)When muscles contract, chemical energy (glucose) is converted to thermal energy (heat)

8. When sitting, what must your thigh muscles do to straighten your legs? a)One muscle contracts & the other relaxes. b)Both musts contract. c)Both muscles relax. d)One must pulls on the bone & the other pulls on the first muscle.

9. Groups of Muscles 1.Voluntary—you can control these Arms, legs, hands, face 2.Involuntary—you can’t control these, don’t have to decide to make these muscles work Muscles around heart

10. Types of Muscle Tissue 1.Skeletal muscle a)Most numerous in body b)Voluntary c)Looks striped (striated) d)Contract quickly, tire easily e)Attached to the bones by tendons (thick bands that pull on the bone as the muscle contracts)

11. Types of Muscle Tissue 2.Smooth muscle a)Found in: walls of stomach, intestine, uterus, etc. b)Involuntary c)No striations d)Contracts and relaxes slowly

12. Types of Muscle Tissue 3.Cardiac muscle a)Only found in heart b)Involuntary c)Has striations d)Contracts 70 times per minute (heartbeat)

13. What attaches muscles to bones? a)Cartilage b)Muscles c)Tendons d)Ligaments

14. Which picture shows smooth muscle? 1. 2. 3. 4.

15. What type of muscle is involuntary and striated? a)Skeletal b)Smooth c)Intestinal d)Cardiac

16. Which is NOT a function of the muscular system? a)To move your body b)To help protect other organs c)To help digest food d)To help pump blood

17. Functions of the Integumentary System 1.Forms a protective covering over the body

18. Functions of the Integumentary System 1.Forms a protective covering over the body 2.Maintains homeostasis—regulates bodytemperature

19. Functions of the Integumentary System 1.Forms a protective covering over the body 2.Maintains homeostasis—regulates body temperature 3.Excretes wastes— sodium chloride (salt), water, urea

20. Functions of the Integumentary System 1.Forms a protective covering over the body 2.Maintains homeostasis—regulates body temperature 3.Excretes wastes— sodium chloride (salt), water, urea 4.Sensory organ— nerve endings are sensitive to temperature, pressure, & touch

21. Functions of the Integumentary System 1.Forms a protective covering over the body 2.Maintains homeostasis—regulates body temperature 3.Excretes wastes— sodium chloride (salt), water, urea 4.Sensory organ—nerve endings are sensitive to temperature, pressure, & touch 5.Produces vitamin D in the epidermis using sunlight

22. Which is NOT a function of the integumentary system? a)To prevent substances from entering the body b)To help keep body temperature stable c)To remove wastes from the body d)To absorb oxygen into the body

23. Layers of Skin 1.Epidermis = surface layer a)Cells on top are dead b)New cells are constantly produced at the bottom c)Cells produce melanin (pigment that gives you skin color)

24. Layers of Skin 2.Dermis = layer under epidermis a)Thicker than epidermis b)Contains blood vessels, nerves, oil and sweat glands c)Fat cells stored under the dermis

25. Which part of the skin makes new skin cells? a)Epidermis b)Dermis c)Fat cells d)Sweat glands
