If you ever break a bone or suffer from a bone disease, your doctor will use the bones’ scientific names to describe your condition; it could be very useful for you to know the names of the most common bones.</p><p>Diagram A Diagram B Part 2. NAMING THE MUSCLES OF THE HUMAN BODY</p><p>Think of the different ways in which you can move your body. While throwing a ball, for example, you grip with your fingers, raise your arm, bend your wrist, and arch your back. Suddenly your arm swings down, your wrist moves forward, your back flexes, your fingers straighten, and you release the ball. You continually shift your weight and reposition, your legs; your shoulders and your other arm move to accommodate the throwing movement and to keep and maintain balance; your head moves as you watch the target or the flight of the ball. All of these movements happen because the muscles in your arm, neck, shoulder, back, trunk, legs, hands, and feet are attached to your skeleton, and these muscles pull your bones. In this project, you will learn to name and describe some of the major muscles that move your skeleton. Conclusion Questions:</p><p>1. Another set of bones, similar to the carpals, are called “tarsals.” What part of the foot do the tarsals make? ______</p><p>2. On the foot, the short bones that are similar to the metacarpals are called “metatarsals.” What part of the foot do the metatarsals make? ______</p><p>3. The lower arm has two long bones, the ulna and the radius. Why do you think it is necessary to have two bones in the lower arm instead of just one? ______</p><p>4. Many murder mysteries feature a corpse with a dagger through its ribs; obviously, the ribs do not do a perfect job of protecting the organs inside them. Better protection could be provided by a solid bony case like the skull; can you see any disadvantages in such an arrangement? Explain. ______5. Suppose your brain were protected only by a set of bones with openings between them, like the ribs. Would this be satisfactory? Explain your answer. ______6. Match each muscle to its function. One letter will be used more than once. ____The muscle that tilts your head backward ____The triangular muscle that helps you to lift your arm above your head a. biceps femoris ____The muscle that helps to lift you onto your toes b. trapezius ____The muscle that pulls your leg back as you prepare to kick a ball c. sartoris ____The muscle that pulls your leg rapidly forward so that you can kick the ball d. gastrocnemius ____The muscle that straightens your arm e. triceps brachii ____The muscle that shrugs your shoulders f. deltoid ____The muscle that helps you to sit with your legs crossed g. pectoralis major ____The muscle that helps you to move your arm toward your body h. rectus femoris</p><p>7.
