Exercise 14 Skeletal Muscles and their Actions.docx

Reviewing Your Knowledge A. Muscle Compartment Terms Muscles work in groups when they perform multifaceted movements. Write the anatomical term that describes the muscle of a compartment that performs the following action. __________ 1.Muscle that is opposing an action Agonist Muscle __________ 2.Muscle that stabilizes the origin of a prime mover Antagonist Muscle __________ 2.Small muscle that aids prime mover Fixator Muscle __________ 4.Prime mover. Muscle that is causing an action Synergist Muscle B. Criteria for Naming Muscles For each of the muscles below, state the criteria used for naming the muscle. For example, serratus anterior is a saw-toothed anterior muscle. 1. Latissimus dorsi Widest muscle 2. Rectus abdominis muscle fibers parallel to body midline 3. Trapezius Trapezoid shape 4. Biceps brachii Has 2 origins 5. Levator scapulae Raises or elevates body part 6. Flexor carpi radialis Decreases a joint angle 7. Piriformis Pear shaped 8. Gluteus medius Middle sized muscle 9. Rhomboid major Larger muscle, Dimond shaped 10. Pectoralis major Larger muscle C. Anatomy Review For Figures 14.12 (a) and 14.12 (b), write the name of the skeletal muscle next to the number.
