Occipitalis Origin
The occipitalis muscle starts at the superiorAbove or toward the upper part of the body. nuchal line of the occipital bone. This is a ridge-like area on the posterior (back) part of the skull. It also originates from the mastoid part of the temporal boneBones on the sides of the skull near the ears; house structures of hearing and balance., which is situated just below the ear. This origin provides a firm attachment point for the muscle and allows it to exert its effects on the scalp.
Occipitalis Insertion
From its origin, the muscle fibers of the occipitalis run forward and upward. The occipitalis muscle then inserts into the galea aponeurotica. This is a broad, fibrous sheet that spans across the top of the skull. It connects the frontalis muscle at the forehead. This insertion allows the occipitalis to work with the frontalis muscle. Together, they move the scalp and influence the positioning of the skinThe body’s largest organ, providing protection and regulation. on the head.
