The Morphological Structure of the Greater Occipital Nerve in a Male

Description

Posterior scalp and upper cervical soft tissues are rendered in a male subject, with the greater occipital nerve (C2 dorsal ramus, medial branch) traced from the suboccipital region to its cutaneous arborization over the occiput. Its course ascends deep to the inferior oblique and semispinalis capitis, then pierces the muscle and the tendinous attachment of trapezius near the superior nuchal line to become superficial. Occipital vessels travel nearby, and the nerve’s winding path is shown in relation to the posterior border of sternocleidomastoid and the midline nuchal musculature. Clear landmarks. Clinically, this anatomy maps directly onto occipital neuralgia and cervicogenic headache patterns, where irritation of the greater occipital nerve often occurs at the points where it traverses semispinalis capitis and pierces trapezius. The depiction helps differentiate pain referral from C2 dorsal ramus entrapment versus upper cervical facet sources and clarifies why tenderness is frequently elicited just inferior to the superior nuchal line, lateral to the external occipital protuberance. For procedural work, the spatial relationship to the occipital artery supports safer, more reliable greater occipital nerve blocks and can guide surgical decompression planning when conservative management fails. Neurology, pain medicine, and anatomy faculty can place this plate directly into teaching on posterior scalp sensory innervation, dorsal rami organization, and the myofascial tunnels that predispose to entrapment neuropathy. It also suits clinical handouts and review figures for occipital nerve block technique, radiofrequency interventions targeting C2-related pain, and operative discussions of decompression along the nerve’s muscular pierce points.
