Insertion is the attachment on the bone that moves
A tendon connects bone to muscle and a ligament connects bone to bone. The actual point of attachment where a muscle connects to a bone is called the process(n) of the bone. This is a bulge in the bone where muscle can attach to provide movement. Not all muscles will attach to bone via a bony process as described above, it may can sometimes by a fleshy attachment (e.g. sternocleidomastoid to clavicle). So broader terms are simple origin and insertion, origin being the attachment that tends to be fixed and insertion being the attachment that tends to move when the muscle is contracted.
Where a muscle attaches to a bone is at the origin and insertion points. The origin is the immovable (or slightly moveable) attachment point and the the insertion is the movable attachment point. During contraction the insertion moves towards the origin. HOW a muscle attaches to a bone is through tendons.
origin
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.

Legment and tendons
The attachment points of muscles to bones are called tendons. Tendons are tough, fibrous tissues that connect muscle to bone and allow the muscle to exert force on the bone, enabling movement. The point of attachment on the bone is typically referred to as the insertion point, while the point on the muscle where the tendon originates is called the origin.
The term that identifies the site where a muscle attaches to the bone it pulls on is called the "insertion." This is typically the more movable attachment of the muscle, as opposed to the origin which is the less movable attachment site.
It provides a structure for the attachment of muscles and such.
funny bone
The origin and attachment of a muscle play crucial roles in facilitating movement. The origin is the fixed point where a muscle attaches to a bone, while the attachment (or insertion) is the point where the muscle connects to the bone that moves. When a muscle contracts, it pulls on the insertion, causing movement at the joint between the two bones. This coordinated action allows for various movements, such as flexion, extension, and rotation, depending on the muscle's alignment and function.
