What is Origin?
The origin of the muscle fibers is referred to as the “origin“. It is the location where a muscle joins a bone, cartilage, or other tissue. The attachment points of muscles can differ according to the muscle, and they frequently have one or many places of origin. For instance, in the upper arm’s biceps brachii muscle, the scapula’s supraglenoid tubercle is the source of the muscle’s long head, while the coracoid process is the source of the muscle’s short head. The two heads of the biceps muscle originate at these attachment sites. Understanding a muscle’s development is crucial to understanding how it works and how movement occurs. Joint movement is the outcome of a muscle contracting because the insertion, or opposite end of the muscle, is drawn towards the origin.

Difference between Origin and Insertion
Origin and Insertion are sites where muscles are attached. The beginning region of a muscle at the site of attachment is referred to as its origin. The origin is usually found nearer the midline of the body or the organ’s center. The place of connection where a muscle ends is referred to as the muscle’s insertion. The insertion is often found farther from the midline or the center of an organ than the origin and more distal, or away from the center of the body. When muscle fibers contract, they pull on the insertion site, causing this movement.
