The triceps muscle is the primary muscle used in a cable extension.
The attachment of the muscle that is on the moving bone is known as the insertion. In contrast, the origin is the attachment of the muscle on the non-moving bone.
I think its the humerus.
Both the origin and insertion points attach muscles to bone. The muscles are moving the bones so they must be attached directly to bone.

The insertion of a muscle is the place where it attaches to the bone that the muscle moves.
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.
Triceps is a very powerful muscle on the backside of your arm. It has medial, lateral and long head. That is why the name triceps goes. Medial and long heads arise from the humerus bone and long bone arise from the infraglenoid tubercle of scapula bone. It is inserted on the olecranon process of the ulna bone of the forearm. It gets the nerve supply from the radial nerve, on it's way to extensor compartment of the forearm.
Biceps are the top part of your upperarm, your Triceps are the bottom part of your upperarm, and your deltoids are the muscles on your arm next to your shoulders.
