According to Anthony's Textbook of Anatomy and Physiology the origin is that point of attachment that does not move when the muscle contracts, and the point of attachment that does move when the muscle contracts is the insertion. Muscles and muscle groups that that directly perform specific movements are prime movers or agonists.
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 two or more points of a muscle attachment are called its origin point and its insertion point, insertion usually being farther away from the center of the body. Such as the bicep its origin point is at the ball of the humorous and its insertion point is at the ulna.

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 muscles and the bone work together and attached
It contracts to move bones together.

A tendon connects bone to muscle and a ligament connects bone to bone. The actual point of attachment where a muscle connects to a bone is called the process(n) of the bone. This is a bulge in the bone where muscle can attach to provide movement. Not all muscles will attach to bone via a bony process as described above, it may can sometimes by a fleshy attachment (e.g. sternocleidomastoid to clavicle). So broader terms are simple origin and insertion, origin being the attachment that tends to be fixed and insertion being the attachment that tends to move when the muscle is contracted.
