context_page_description: The cervical spinal nerve 1 is a spinal nerve of the cervical segment. C1 carries predominantly motor fibres, but also a small meningeal branch that supplies sensation to parts of the dura around the foramen magnum.
  It originates from the spinal column from above the cervical vertebra 1.
  Muscles innervated by this nerve are:
  Geniohyoid muscle- through Hypoglossal nerve
  Rectus capitis anterior muscle
  Longus capitis muscle
  Rectus capitis lateralis muscle
  Splenius cervicis muscle
  Rectus capitis posterior major muscle
  levator scapulae muscle
  Thyrohyoid muscle – through hypoglossal nerve
  Omohyoid – through Ansa cervicalis
  Sternohyoid – through Ansa cervicalis

  Muscles innervated by this nerve are:
  Geniohyoid muscle- through Hypoglossal nerve
  Rectus capitis anterior muscle
  Longus capitis muscle (partly)
  Rectus capitis lateralis muscle
  Splenius cervicis muscle (partly)
