Origin and Insertion
One of the points of attachment is the ORIGIN (typically the non-moving point of attachment). The other point of attachment is the INSERTION (typically the moving point of attachment).
For example - when the brachialis muscle (located on the upper arm) contracts - it shortens the distance between the origin (on the humerus - the upper arm bone and the insertion (on the radius - the forearm bone). The humerus does not move, but the radius does move - it moves closer to the humerus.

The greater and lesser trochanters.
The attachment points of muscles to bones are called tendons. Tendons are tough, fibrous tissues that connect muscle to bone and allow the muscle to exert force on the bone, enabling movement. The point of attachment on the bone is typically referred to as the insertion point, while the point on the muscle where the tendon originates is called the origin.
Origin is typically the proximal attachment of a muscle because it is the least moveable. The distal attachment is where a muscle inserts.
Where a muscle attaches to a bone is at the origin and insertion points. The origin is the immovable (or slightly moveable) attachment point and the the insertion is the movable attachment point. During contraction the insertion moves towards the origin. HOW a muscle attaches to a bone is through tendons.
The two attachment points are the origin and insertion. The origin is the immovable (or slightly moveable point. The insertion is the movable point. The insertion always moves towards the origin.
The less movable attachment point of a muscle is called the origin. This is typically the point of attachment that remains relatively fixed during muscle contraction, while the other end, known as the insertion, moves towards the origin.
An injury to the body of the muscle or attachment of the tendon is known as a strain. To treat a strain, the affected limb should be elevated and a cold compress applied to the area.
The term that identifies the site where a muscle attaches to the bone it pulls on is called the "insertion." This is typically the more movable attachment of the muscle, as opposed to the origin which is the less movable attachment site.
. The insertion is considered the moveable part, or the part that attaches farthest from the midline or center of the body. The insertion in known as the distal attachment.
