Anatomy Of Cervical Muscles

Cervical spine anatomy there are seven vertebrae in the cervical spine neck area which surround the spinal canal and the spinal cord. Discs made up of gelatinous material act as cushioning between these vertebra with nerves passing out of the spinal canal between the disc and vertebra.

Therefore for this articles purposes the neck muscles may be divided into four major structural groups each in its own quadrant.

Anatomy of cervical muscles. The musculature of the neck is comprised of a number of different muscle groups. Rectus capitis lateralis originates from the first. The cervical spine straightens or moves directly backward with the chin tilting up.

Together the scalenes act to flex the neck. The muscles in the neck are responsible for the movement of the head in the cervical region in all directions. The posterior scalene also originates from the cervical spine but attaches instead to the second rib.

They move the head in every direction pulling the skull and jaw towards the shoulders spine and scapula. The cervical spine section contains seven vertebrae c 1 through c 7 and eight nerve pairs c 1 through c 8. Head and neck motions typically involve one or more of the following movements of the cervical spine.

Longus capitis begins between the third and sixth cervical vertebrae. They can also be recruited as accessory muscles of respiration. The fan shaped trapezius muscles extend from the back of the skull down to the middle of the back along the spine and fan over into the shoulders.

These muscles give the sides of the neck their. These muscles are innervated by the posterior rami of various cervical spinal nerves. The neck muscles including the sternocleidomastoid and the trapezius are responsible for the gross motor movement in the muscular system of the head and neck.

Muscles of the neck. The top section of the spine is the cervical section which contains nerves that innervate muscles of the head neck and thoracic cavity as well as transmit sensory information to the cns. The cervical spine bends directly forward with the chin tilting down.

Rectus capitis anterior begins at the first cervical vertebrae. The musculature of the neck is comprised of a number of different muscle groups. Longus colli begins between the third and sixth cervical vertebrae.
