Upper fibres-from maxilla opposite molar teeth.
lower fibres-from mandible opposite molar teeth
middle fibres-from pterygomandibular raphe.
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).
The origin is the "immovable" point of attachment of a muscle to a bone.
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.
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.
The two attachment points are the origin and insertion. The origin is the immovable (or slightly moveable point. The insertion is the movable point. The insertion always moves towards the origin.
The end of the muscle that is attached to the stationary bone is the point of origin. The muscle end that is attached to the moving bone is the point of insertion, and the action is what the muscle actually does.
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.
A muscle attaches to a bone at two points the origin and insertion. The origin is the immovable (stationary) point. The insertion is the movable point. The insertion always moves towards the origin.Fibrous joint? The definition: consists of two bones that are united by fibrous tissue and exhibit little or no movement.
Ligaments attach bone to bone. Tendons attach muscles to bone.No, the origin is the attachment of a muscle to a stationary bone. You may have commonly heard of this as a "fixed end".
The two or more points of a muscle attachment are called its origin point and its insertion point, insertion usually being farther away from the center of the body. Such as the bicep its origin point is at the ball of the humorous and its insertion point is at the ulna.

origin is where the muscle is attached and is the "starting point" where the insertion is where the muscle ends "the ending point" the insertion of the muscle is what moves, while the origin in most cases stays still.
