insertion
The "movable" end of a muscle is called the insertion. The "immobile" end is called the origin. Shortening, or contraction, of a muscle causes the origin and insertion to become closer to one another.
Insertion
INSERTION
Insertion point, which most probably is a tendon.
muscle origin
muscles connect to ligaments connect to bones!
The origin is the "immovable" point of attachment of a muscle to a bone.
The less movable attachment point of a muscle is called the origin. This is typically the point of attachment that remains relatively fixed during muscle contraction, while the other end, known as the insertion, moves towards the origin.
muscle attaches to bone by a tendon. muscle is attached to an immovable bone, this is called orgin, and the other end of the muscle is attached to a movable bone. this is called insertion.
The sarcomere is the contractile unit of a muscle fiber.
PENIS!
The immovable part of muscle bundles is called the origin. This point is where the muscle attaches to a stationary bone or structure, providing a stable anchor during muscle contraction. In contrast, the other end of the muscle, known as the insertion, attaches to a movable bone, allowing for movement when the muscle contracts.
