Origin is typically the proximal attachment of a muscle because it is the least moveable. The distal attachment is where a muscle inserts.
origin
Proximal means nearest the point of attachment or origin.
Origin
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 two attachment points are the origin and insertion. The origin is the immovable (or slightly moveable point. The insertion is the movable point. The insertion always moves towards the origin.
Origin
Origin
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,
Origin is typically the proximal attachment of a muscle because it is the least moveable. The distal attachment is where a muscle inserts.
false
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.
