Extension | Straightening a joint so that the angle increases or the parts move farther apart. |
Hyperextension | Excessive extension of a joint beyond the anatomical position. |
Dorsiflexion | Flexing the foot at the ankle (pulling toes toward the tibia) |
Plantar Flexion | Extending the foot at the anke (pointing the toes) |
Abduction | Moving a part away from the midline (raising arms away from the sides) |
Adduction | Moving a part toward the midline (returning arms to the sides from raised position) |
Supination | Turning the hand so the palm is upward or turning the foot so that the medial margin is raised. |
Pronation | Turning the hand so the palm is downward or turning the foot so that the medial margin is lowered. |
Eversion | Turning the foot so the sole is outward |
Inversion | Turning the foot so the sole is inward |
Protraction | Moving a part forward (thrust the chin forward) |
Retraction | Moving a part backward (pull the chin forward) |
Elevation | Raising a part (shrugging the shoulders) |
Depression | Lowering a part (dropping the shoulders) |
Origin | Immovable end of a muscle |
Insertion | Moveable end of a muscle |
Prime Mover | The primary muscle or muscles that cause a desired joint to move |
Synergists | Muscles that contract to assist the prime mover |
Antagonists | Muscles that resist a prime mover and causes movement in the opposite direction |
Epicranius | Raises eyebrow as if surprised, consists of two muscles frontalis and occipitalis |
Frontalis | Lies over the frontal bone |
Occipitalis | Lies over the occipital bone |
Epicranial Aponeurosis | Tendinous membrane uniting the frontalis and occipitalis that cocvers the cranium like a cap. |
Orbicularis Oculi | Surrounds the eye and closes the eye as in blinking |
Orbicularis Oris | Encircles the mouth and closes lips (also puckers lips as in kissing) |
Buccinator | Located in the wall of the cheek and compress the ckeck inward. Aids in mastication and smetimes called the "trumpeter muscle". |
Zygomaticus | Origin is on the zygomatic bone and inserts the lateral margin obicularis oris. Raises the corners of the mouth as in smiling. |
Platysma | Sheet like muscle that is located on the anterior portion of the neck. Pulls the mouth downward as in frowning and also helps lower the mandible. |
Masseter | Origin is lower boreder of zygomatic arch. Elevates mandible. |
Temporalis | Fan-shaped muscles that originates on the side of the skull. Fibers pass beneath the zygomatic arch and insert on the coronoid process. Elevates the mandible. Assoc. with TMJ |
Medial Pterygoid | Elevates the mandible |
Lateral Pterygoid | Opens mouth (depresses mandible), pulls the mandible forward, and moves the mandible from side to side. |
