the insertion is more moveable.
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
The origin is the "immovable" point of attachment of a muscle to a bone.
muscle origin
no one cares
The origin is the immovable end, while insertion is the movable end.Some muscles have more than one origin, like the biceps brachii. The insertion of the biceps brachii is attached to the radius of your forearm while the origins are located on your scapula.
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.

Insertion is the attachment on the bone that moves
Your skeleton does not actually produce movement. That is the job of your muscles. When they contract they pull on bones which are joined together by joints. The joints function much the same as a fulcrum and produce three different types of levers depending on where the muscles attach. The most stable attachment is called the origin, and the more movable one is called the insertion. It is the bone that has the insertion end of the muscle that we are familiar with as the bone that moves.
The origin refers to the muscle attachment that is more stable. The tendon that attaches the muscle to its origin can be called the origin tendon,
if you're speaking anatomically (as in origin and insertion), the origin of the bicep curl would be its fixed attachment at the supraglenoid tubercle and the coracoid process (two heads), as a bicep curl is an open chain motion (distal end is free moving --> proximal end is the origin). it would be more correct, though, to say refer to it as the origin of the biceps during a bicep curl.
