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,
the place where the muscle begins.
Reverse origin and insertion refers to the changing of the attachment points of a muscle. When the origin and insertion of a muscle are reversed, the muscle's previous insertion point now becomes the origin, and vice versa. This can have an impact on the muscle's function and movement.
depends on which muscle but the opposite muscle sometimes contracts aswell to stabalize the joint some relaxes ...
The fixator of a muscle stabilizes the muscle at the point of origin.
The origin of a muscle is where the muscle starts ("the starting point"). The insertion of a muscle is where the muscle ends ("the ending point"). Also, the insertion of the muscle is what moves a lot (contrary of the origin where the muscle mostly stays stationary).
Antagonist: Controls movement, opposite of prime mover Prime Mover: Main muscle that is directly responsible for movement Synergist: Aids in movement of muscle
Muscle attaches to a non-moving bone at the muscle's origin.
