Topography:
- Anterior branch of spinal nerve
- From spinal nerve C1, C2, C3, C4
Somatosensory Branches (mechanoreceptors, exteroreceptors, prorioceptors, thermoreceptors)
- Transverse Cervical Nerve (nervus transversus colli) from C2 and C3
○ Divides into inferior branch for the skin of the infrahyoid region, and superior branch for the skin of the suprahyoid region. Superior branch forms superficial ansa cervicalis for platysma
- Greater auricular nerve (nervus auricularis magnus) from C2 and C3
○ Innervates the skin over the ear and parotid glands.
○ Anterior branch for anterior part of auricle and parotid
○ Posterior branch for the posterior parts
- Lesser occipital Nerve (nervus occipitalis minor) from C2 and C3
○ Supplies skin of occiput and the posteror neck and lateral back of neck
- Supraclavicular nerves (Nervi supraclaviculares) from C3 and C4
Motor Branches
- Muscular Branches (rami musculares) from C1-C4
- Deep cervical loop (ansa cervicalis profunda) for the infrahyoid muscles
○ Formed by Superior root (radix superior) - C1 and C2
○ Inferior root (radix inferior) - C2 to C3
Mixed Branches
- Phrenic nerve (nervus phrenicus) - C3 to C5
○ Phrenic branches (rami phrenici)
○ Pericardial branches (rami pericardiaci)
○ Pleural branches (rami pleurales)
○ Phrenicoabdominal branches (rami phrenicoabdominales)
○ Sensory branches for the thymus
- Accessory Nerve (Spinal Part)
