- The seven general types of skeletal muscle. The origin of a muscle is the bone, typically proximal, which has greater mass and is more stable during a contraction than a muscle's insertion. For example, with the latissimus dorsi muscle, the origin site is the torso, and the insertion is the arm.

Difference Between Origin and Insertion • Origin is the end that does not move when the muscle moves while insertion is the end that does move when the muscle moves. • Origin tends to be more proximal while insertion tends to be more origin. • Origin of a muscle attaches to a less movable bone whereas insertion of a muscle attaches to a more moveable bone.• Insertion has less mass than the site of origin. • When a muscle contracts, it pulls insertion towards origin.

What is meant by the origin, insertion, and action of a muscle? The point of origin and insertion are at the end of the muscles. When the muscle contracts (goes smaller) the insertion is pulled towards the origin (which is fixed) which creates movement. ........................... · 8 years ago.

MUSCLES AND MOVEMENT The insertion is where it joins the moving bone. When a muscle contracts, the insertion moves towards the origin. TENDONS. Tendons are the cords and straps that connect muscles to bones. At the bone, the fibres of the tendon are embedded in the periosteum of the bone.

- Muscle pairs. Antagonistic pairs of muscles create movement when one (the prime mover) contracts and the other (the antagonist) relaxes. Examples of antagonistic pairs working are: 1  the quadriceps and hamstrings in the leg. 2  the biceps and triceps in the arm.

Anatomical terms of muscle An example of an antagonisic pair is the biceps and triceps; to contract-the triceps relaxes while the biceps contracts to lift the arm. Reverse motions need antagonistic pairs located in opposite sides of a joint or bone, including abductor-adductor pairs and flexor-extensor pairs.hese consist of an extensor muscle, which opens the joint (by increasing the angle between the two bones) and a flexor muscle, which does the opposite by decreasing the angle between two bones. Not all muscles are paired in this way. An example of exception is the deltoid.

- In large, flat muscles the tendon is often a flattened sheet called an aponeurosis. Cords of connective tissue also bind bone to bone across joints; these are called ligaments. The two attachments of a muscle are called the origin and the insertion. The end of a muscle which is nearer to the midline of the body, which is more proximal, or less movable is called the origin. The end of a muscle furthest from the dorsal midline, more distal or more movable is called the insertion.

Anatomical terms of muscle Antagonist and agonist muscles often occur in pairs, called antagonistic pairs. As one muscle contracts, the other relaxes. An example of an antagonisic pair is the biceps and triceps; to contract-the triceps relaxes while the biceps contracts to lift the arm.Reverse motions need antagonistic pairs located in opposite sides of a joint or bone, including abductor-adductor pairs and flexor-extensor pairs.gonist muscles cause a movement to occur through their own contraction. For example, the triceps brachii contracts during the up phase of a push-up (elbow extension). During the down phase of a push-up, the same triceps brachii actively controls elbow flexion while relaxing.

- A muscle that has more than one attachment at locations that do not move, called origins, and only one attachment at the location that does move, called the insertion, is said to have more than one head. The term biceps means two heads; the term triceps means three heads; and the term quadriceps means four heads.

MUSCLES AND MOVEMENT HOW MUSCLES WORK. A voluntary muscles usually works across a joint. It is attached to both the bones by strong cords called tendons. When the muscles contracts, usually just one bone moves. For example when the biceps in the arm contracts, the radius moves but the scapula does not.USCLE WORKING IN PAIRS. Muscles usually work in pairs or groups, e.g. the biceps flexes the elbow and the triceps extends it. This is called antagonistic muscle action. The working muscle is called the prime mover or agonist. (it s in agony!) The relaxing muscle is the antagonist.

Anatomical terms of muscle The insertion and origin of a muscle are the two places where it is anchored, one at each end. The tissue of the attachment is called an enthesis. The origin of a muscle is the bone, typically proximal, which has greater mass and is more stable during a contraction than a muscle's insertion. For example, with the latissimus dorsi muscle, the origin site is the torso, and the insertion is the arm.

Thread: What is the difference between muscle insertion and muscle origin? Muscle origin and insertion are terms that describe where the muscle attaches to the bones / connective tissues. They are relative. Generally, the origin is where the muscles originates on the body (usually a bone, but not always) of the stationary part. The insertion is where the muscle attaches on the bone of the moving lever across a single, or multiple, joint lines. When the muscle contracts, it pulls the insertion to the origin.
