Question
Define the terms origin and insertion with relation to muscles
Solution
In the context of muscles, "origin" and "insertion" are terms used to describe the attachment points of muscles as they relate to bone.
-
Origin: The origin of a muscle is the point where the muscle attaches to a fixed bone—typically the bone that remains immobile for a particular action. The origin is often proximal, which means it is closer to the center of the body.
-
Insertion: The insertion of a muscle is the point where the muscle attaches to the bone that is moved by the muscle. The insertion is often distal, or further from the center of the body.
In a nutshell, when a muscle contracts, it pulls on the bone at the insertion point, moving it towards the origin point.
