INSERTION
The "movable" end of a muscle is called the insertion. The "immobile" end is called the origin. Shortening, or contraction, of a muscle causes the origin and insertion to become closer to one another.
muscles connect to ligaments connect to bones!
Origin
A muscle insertion is the end of a muscle attached to the free-moving bone of its joint. A muscle origin is the end of the muscle attached to the relatively fixed bone of the joint.
the position at which the end of the muscles is attached by means of a tendon to a movable bone whereas insertion is the attachment of muscles to the movable bone.. also origin is generally closer to the mid line of the body whereas insertion is farther away..

origin is where the muscle stars (generally the proximal attachment or in some cases medial) insertions is where the muscle ends (generally the distal or lateral attachment) for example the origin of the bicep would be the shoulder while the insertion is the elbow
I think you may be talking about origin and insertion points which are the two points of attachment for a muscle. The origin is attached to the immovable (or less movable) bone. The insertion is attached to the movable bone. The insertion always moves towards the origin.
Alright, now that the riff-raff is outta the way - Origin is the attachment of a muscle (tendon) that is stationary. Insertion is at the other end of the muscle that is attached to a movable bone, also with a tendon. Hoped that helps.
Insertion
There are two points of attachment for a (skeletal) muscle, the origin and the insertion. The origin is the immovable (or slightly movable) part. The insertion moves towards the origin.
