Detailed explanation-1: -Origin is relatively the less movable end of the muscle/tendon that is attached to a bone. Insertion is the more flexible end of the muscle that is usually attached to a bone via tendons.
Detailed explanation-2: -Muscle origin is a term referring to one end of a muscle, generally at the location where it attaches to a bone. The main part of the muscle called the belly of the muscle, then crosses over the gap between this bone and another usually adjacent bone-to attach there.
Detailed explanation-3: -The origin is the fixed point that doesn’t move during contraction, while the insertion does move.
Detailed explanation-4: -The end of the muscle closest to the torso is referred to as origin of muscles. The attachment of a muscle to a more sturdy bone is referred to as the insertion of muscles. Tendon connects the muscle to the bone at these sites. The bicep muscle, for example, has its origin in the shoulder.
