MUSCLE PHYSIOLOGY

Detailed explanation-1: -Muscles are attached to the bones by tendons. The insertion is the point of attachment. It is that part of the body which acts as the distal end of the attachment of a muscle to a bone. The insertion has the ability to be moved by the muscle.

Detailed explanation-2: -The moveable end of the muscle that attaches to the bone being pulled is called the muscle’s insertion, and the end of the muscle attached to a fixed (stabilized) bone is called the origin.

Detailed explanation-3: -Muscle Insertion Definition A muscle has two ends that each attach to bone: the muscle’s origin and the muscle’s insertion. At both of these points, tendons attach the muscle to bone. Muscle insertion refers to a muscle’s distal attachment-the end of the muscle furthest away from the torso.

Detailed explanation-4: -Muscles pull. The origin is the fixed point that doesn’t move during contraction, while the insertion does move.

Detailed explanation-5: -Origin is relatively the less movable end of the muscle/tendon that is attached to a bone. Insertion is the more flexible end of the muscle that is usually attached to a bone via tendons. It is the proximal end that is attached to the less movable bone. It is the distal end that is attached to the more movable bone.
