It originates from the spinal column from above the cervical vertebra 1 (C1).
Muscles innervated by this nerve are:
- Geniohyoid muscleGeniohyoid muscleThe Geniohyoid muscle is a narrow muscle situated superior to the medial border of the mylohyoid muscle. It is named for its passage from the chin to the hyoid bone.-Origin and insertion:...
- through Hypoglossal nerveHypoglossal nerveThe hypoglossal nerve is the twelfth cranial nerve , leading to the tongue. The nerve arises from the hypoglossal nucleus and emerges from the medulla oblongata in the preolivary sulcus separating the olive and the pyramid. It then passes through the hypoglossal canal... - Rectus capitis anterior muscleRectus capitis anterior muscleThe rectus capitis anterior is a short, flat muscle, situated immediately behind the upper part of the Longus capitis....
- Longus capitis muscleLongus capitis muscleThe longus capitis muscle , broad and thick above, narrow below, 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...
(partly) - Rectus capitis lateralis muscleRectus capitis lateralis muscleThe 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.-See also:* atlanto-occipital joint...
- Splenius cervicis muscleSplenius cervicis muscleThe splenius cervicis is a muscle in the back of the neck. It arises by a narrow tendinous band from the spinous processes of the third to the sixth thoracic vertebrae; it is inserted, by tendinous fasciculi, into the posterior tubercles of the transverse processes of the upper two or three...
(partly) - Rectus capitis posterior major muscleRectus capitis posterior major muscleThe Rectus capitis posterior major 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.In 2011, Scali et al.,...
