Index Cervical spinal nerve 1

The cervical spinal nerve 1 (C1) is a spinal nerve of the cervical segment. [1]

Ansa cervicalis

The ansa cervicalis (or ansa hypoglossi in older literature) is a loop of nerves that are part of the cervical plexus.

Atlas (anatomy)

In anatomy, the atlas (C1) is the most superior (first) cervical vertebra of the spine.

Geniohyoid muscle

The geniohyoid muscle is a narrow muscle situated superior to the medial border of the mylohyoid muscle.

Hypoglossal nerve

The hypoglossal nerve is the twelfth cranial nerve, and innervates all the extrinsic and intrinsic muscles of the tongue, except for the palatoglossus which is innervated by the vagus nerve.

Levator scapulae muscle

The levator scapulae is a skeletal muscle situated at the back and side of the neck.

Longus capitis muscle

The longus capitis muscle (Latin for long muscle of the head, alternatively rectus capitis anticus major), is broad and thick above, narrow below, and arises by four tendinous slips, from the anterior tubercles of the transverse processes of the third, fourth, fifth, and sixth cervical vertebræ, and ascends, converging toward its fellow of the opposite side, to be inserted into the inferior surface of the basilar part of the occipital bone.

Omohyoid muscle

The omohyoid muscle is a muscle that depresses the hyoid.

Rectus capitis anterior muscle

The rectus capitis anterior (rectus capitis anticus minor) is a short, flat muscle, situated immediately behind the upper part of the Longus capitis.

Rectus capitis lateralis muscle

The Rectus capitis lateralis, a short, flat muscle, arises from the upper surface of the transverse process of the atlas, and is inserted into the under surface of the jugular process of the occipital bone.

Rectus capitis posterior major muscle

The rectus capitis posterior major (or rectus capitis posticus major, both being Latin for larger posterior straight muscle of the head) arises by a pointed tendon from the spinous process of the axis, and, becoming broader as it ascends, is inserted into the lateral part of the inferior nuchal line of the occipital bone and the surface of the bone immediately below the line.

Spinal cord

The spinal cord is a long, thin, tubular bundle of nervous tissue and support cells that extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column.

Spinal nerve

A spinal nerve is a mixed nerve, which carries motor, sensory, and autonomic signals between the spinal cord and the body.

Splenius cervicis muscle

The splenius cervicis (also known as the splenius colli) is a muscle in the back of the neck.

Sternohyoid muscle

The sternohyoid muscle is a thin, narrow muscle attaching the hyoid bone to the sternum, one of the paired strap muscles of the infrahyoid muscles serving to depress the hyoid bone.

Thyrohyoid muscle

The thyrohyoid muscle is a small skeletal muscle on the neck which depresses the hyoid and elevates the larynx.
