Anatomy of the greater occipital nerve

The greater occipital nerve (GON) is the medial branch of the dorsal primary ramus of the second cervical nerve.

The GON innervates the muscles of the posterior neck: The semispinalis capitis and the multifidus cervicis. It also supplies cutaneous branches to the posterior scalp and meningeal branches to the posterior cranial fossa. And it supplies pain and proprioceptive branches for the first cervical nerve for innervation of the suboccipital muscles.
