Body Movement (terminology)
| Question | Answer |
|---|---|
| _______ is: the decrease of angle formed by the bones at a joint. | Flexion |
| _______ is: the increase of the angle formed by the bones at a joint. | Extension |
| Dorsiflexion | Flexing of the foot upward |
| Plantar Flexion | Moving the sole of the foot downward, or flexion of the toes |
| Extension of the foot at the ankle is the same as _______. | Plantar flexion |
| Movement of a limb away from the midline of the body is called _______. | Abduction |
| Movement of a limb toward the midline of the body is called _______. | Adduction |
| 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 |
| Rotation | The movement of a body part around its longitudinal axis |
| Circumduction | Rotation of a body part in a circular motion |
| Of the head, arm, and leg - all of which can be rotated - which can be circumducted? | Only the arm and leg |
| Sphincter Muscle | A circular muscle that surrounds an opening of the body |
| 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 |
| Smooth movement requires that each muscle _______ while the opposing muscle _______. | - Relax - Contracts |
