Detailed explanation-1: -The point where the muscle is attached to a bone that moves is called the insertion. The point where the muscle is attached to a bone that remains in a fixed position is called the origin.
Detailed explanation-2: -Skeletal Muscle Attachments: The point of attachment of a muscle that remains relatively stationary when the muscle contracts is the muscle’s origin. The point of attachment that moves when the muscle contracts is the muscle’s insertion.
Detailed explanation-3: -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. It has more muscle mass.
Detailed explanation-4: -Muscles pull. The origin is the fixed point that doesn’t move during contraction, while the insertion does move.
