Description
The rectus capitis anterior muscle is a small, slender muscle located in the neck. It originates at the anterior arch of the atlas (first cervical vertebra), and extends downward and forward to insert into the base of the skull. The rectus capitis anterior muscle is located deep to (beneath) the sternocleidomastoid muscle, a large muscle in the neck that is visible from the outside.
The rectus capitis anterior muscle has several important functions in the head and neck. It helps to flex the neck and head, and also helps to stabilize the cervical spine. It is also involved in respiration, as it helps to elevate the rib cage during inspiration.
The rectus capitis anterior muscle is innervated by the cervical spinal nerves. It is a voluntary muscle, meaning that it can be controlled voluntarily by the person.
In some cases, the rectus capitis anterior muscle may be surgically modified or altered to address certain medical conditions, such as problems with neck movement or instability of the cervical spine. It may also be used as a donor muscle for reconstructive surgery in the head and neck region.
