Muscle Roles and Contraction Types 4. Fixator: The fixator in a movement is the muscle(s) that stabilises the origin of the agonist and the joint that the origin spans (moves over) in order to help the agonist function most effectively. In the bicep curl this would be the rotator cuff muscles, the ‘guardians of the shoulder joint’.. Agonist: The agonist in a movement is the muscle(s) that provides the major force to complete the movement. Because of this agonists are known as the ‘prime movers’. In the bicep curl which produces flexion at the elbow, the biceps muscle is the agonist, as seen in the image below.

Supraspinatus The supraspinatus muscle is a rotator cuff muscle located in the shoulder, specifically in the supraspinatus fossa, a concave depression in the rear portion of the scapula, or shoulder blade.he muscle is attached to a flat, strong tendon that is connected to the shoulder joint capsule. Along with the deltoid and pectoralis major muscles, the supraspinatus muscle helps initiate horizontal abduction (raising the arms skyward) of the shoulder.

Antagonist Muscle During a Pushup The agonist is the main muscle responsible for a specific movement. The antagonist opposes the movement of the agonist, and is responsible for the opposing joint movement. For example, the triceps straighten the elbow joint. The biceps, which is responsible for bending the elbow joint, is the antagonist to the triceps.

Levator palpebrae superioris muscle The levator palpebrae superioris originates on the lesser wing of the sphenoid bone, just above the optic foramen. It broadens and decreases in thickness (becomes thinner) and becomes the levator aponeurosis. This portion inserts on the skin of the upper eyelid, as well as the superior tarsal plate. It is a skeletal muscle. The superior tarsal muscle, a smooth muscle, is attached to the levator palpebrae superioris, and inserts on the superior tarsal plate as well.

- A fixator is a stabilizer that acts to eliminate the unwanted movement of an agonist's, or prime mover's, origin. Many muscles are attached to more than one bone. When this happens the muscles are said to be multiarticulate or multijoint muscles.

- muscle we are exercising. The Antagonist is the opposing muscle and acts in contrast to the agonist. The Stabilizer muscles are those that hold a joint in place so that the exercise may be performed. The Assistors help the Agonist muscle doing the work. The stabilizer muscles are not necessarily moving during exercise, but provide . stationary support. For example, when doing biceps curls, the biceps are the agonists, the triceps are the antagonists and various muscles including the deltoids are the stabilizer muscles.

Latissimus dorsi muscle Latissimi dorsi are commonly known as lats, especially among bodybuilders. The latissimus dorsi is responsible for extension, adduction, transverse extension also known as horizontal abduction, flexion from an extended position, and (medial) internal rotation of the shoulder joint. It also has a synergistic role in extension and lateral flexion of the lumbar spine.

Rotator cuff In anatomy, the rotator cuff is a group of muscles and their tendons that act to stabilize the shoulder. Of the seven scapulohumeral muscles, four make up the rotator cuff. The four muscles are the supraspinatus muscle, the infraspinatus muscle, teres minor muscle, and the subscapularis muscle.

Rotator Cuff Repair The rotator cuff consists of muscles and tendons that hold the shoulder in place. It is 1 of the most important parts of the shoulder. The rotator cuff allows a person to lift his and her arm and reach up. It stabilizes the ball-and-socket joint of the shoulder and allows for normal shoulder mechanics.

Muscle Terminology Most movements also involve muscles called synergists, which help the prime mover function more efficiently by reducing unnecessary movement. Some muscles in a group also act as fixators, stabilizing the origin of the prime mover so that the prime mover can act more efficiently.bduction. Movement of a bone, and the limb of which it is a part, away from the mid-line of the body. Verb: To abduct. Abductor. Any muscle that moves one part of the body away from another-or away from the midline of the body. Action. Movement (usually of skin or bone) caused by muscle contractions.

Anatomy of the Eye External (Extraocular) Anatomy. Extraocular Muscles: There are six muscles that are present in the orbit (eye socket) that attach to the eye to move it. These muscles work to move the eye up, down, side to side, and rotate the eye. The superior rectus is an extraocular muscle that attaches to the top of the eye. It moves the eye upward. The inferior rectus is an extraocular muscle that attaches to the bottom of the eye. It moves the eye downward.

Trapezius Muscle The trapezius muscle is a triangular, flat muscle of the shoulder girdle. It is supplied by the accessory nerve (cranial nerve XI) and the cervical plexus (C2-C4). The muscle itself consists of three parts: Descending (or superior) part: runs from the occipital bone and nuchal ligament to the lateral third of the clavicle. Transverse (or middle) part: originates from the spinal processes of the first to fourth thoracic vertebrae and inserts at the acromion.

Difference between synergist& fixators muscles? Best Answer: Two muscles are called synergists if their contraction leads to a movement into the same direction about the axis of a joint. Fixator muscles are all the muscles that serve to fix a joint in a given position during the movement of other joints. The website gives easy-to-understand examples.
