2. Name a muscle that fits each of the following descriptions. a. Is the deepest quadriceps muscle b. Plantar flexes and everts the foot c. Flexes the thigh on the trunk d. Is a powerful thigh extensor e. Is a lateral hamstring muscle f. Laterally rotates and flexes the thigh g. Inserts onto the linea aspera and the adductor tubercle h. Extends the digits i. Is located deep to the gastrocnemius j. Is located just lateral to the anterior crest of the tibia k. Flexes the great toe l. Flexes thigh and laterally bends vertebral column PART II. Putting It All Together A. Review Questions Answer the following questions using your lecture notes, your textbook, and/or your lab notes. 1. Explain how it is possible to predict the action of a muscle if you know its origin and insertion. 2. A patient is rushed to the hospital, where an emergency appendectomy is performed. Indicate the abdominal quadrant and the skin layers that must be penetrated, and then list (in order from most superficial to deepest) each muscle that the surgeon must cut through to make the appendix accessible for removal. Abdominal quadrant: Skin layers penetrated (superficial to deep): Abdominal muscles (superficial to deep): 3. Explain how the flexor carpi ulnaris can be classified as both an agonist and an antagonist. 4. Describe the major muscles and movements involved in each of the following actions: a. Doing jumping jacks b. Drinking water through a straw and eating soup with a spoon
