Rotation of the palm so that it faces the posterior, is called _______. | Pronation |
Rotation of the palm so that it faces the anterior, is called _______. | Supination |
When the arm is not in the anatomical position, turning the palm "downward" is still called _______. | Pronation |
When the arm is not in the anatomical position, turning the palm "upward" is still called _______. | Supination |
Define the term Inversion (as it relates to the foot/feet). | When the sole of the foot is turned inward toward the midline of the body |
Define the term Eversion (as it relates to the foot/feet). | When the sole of the foot is turned outward away from the midline |
When you "Evert" the feet, what happens to the knees? | They pull (or turn) inward
- EVERT = knEEs |

Regarding sphincter muscles, "contraction" causes _______ of the opening; "relaxation" causes _______ of the opening. | - Constriction
- Dilation |
Prime Mover | The primary muscle in the group that produces the desired action |
Synergists | The "assisting muscles" - they impart steadiness and prevent unnecessary action |
Fixators | Muscles that hold structures in position for action |
Muscles are usually arranged in _______ _______ so that the contraction of one muscle, the _______, causes a specific action, and the contraction of the other muscle, the _______, causes the opposite action. | - Antagonist groups
- Agonist
- Antagonists |
