the cervical plexus is a network of nerves formed in the neck.
formation : ventral rami of C1- 4 nerves. except first cervical nerve, other nerves divide into ascending and descending branches. these nerves unite to form loops on the anterior surface of the scalenus medius and levator scapulae muscles. the plexus is covered by the prevertebral fascia. the plexus is superficially related to sternocleidomastoid and internal jugular vein.
branches: they are classified into superficial, deep and communicating branches.
superficial branchesthey are cutaneous branches.transverse cutaneous nerve of neck (C2,3)
lesser occipital nerve(C2)
greater auricular nerve(C2,3)
supraclavicular nerves(C3,4)
deep branchesanterior branches supply:phrenic nerve(C3,4,5)- diaphragm
rectus capitis lateralis (C1)
rectus capitis anterior(C1)
longus capitis(C1-4)
longus colli (C3-8)
inferior limb of ansa cervicalis(C2-3)
scalenus anterior (C4,5,6)
posterior branches supplysternocleidomastoidc2levator scapulae c3,4

communicating branches:superior cervical sympathetic ganglion communicates with C1-4 nerves by grey rami communicantes

What are the four nerve plexuses?
Cervical: C1 - C5Innervates muscles of neck and extend into thoracic cavity, where they control diaphragmatic muscles. Major nerve: Phrenic...which provides entire nerve supply to diaphragm.Brachial: C5-T1Innervates pectoral girdle and upper limbs. Major nerves: Radial nerve, median nerve, ulnar nerve.Lumbar: T12 - L4Innervates pelvic girdle and lower limbs. Major nerves: Genitofemoral nerve, lateral femoral cutaneous nerve, and femoral nerve.Sacral: L4-S5Innervates pelvic girdle and lower limbs. Major nerves: Sciatic nerve (which branches into tibial and fibular nerves) and pudendal nerve.
