title: [The connectivity between the greater occipital nerve and adjacent structures: anatomo-clinical considerations].
abstract: In order to offer anatomical basis that aid for clinical interpretation of headache of cervical origin a macro-mesoscopic study of greater occipital nerve and its subcutaneous rise out site was accomplished. The authors observed that in its course this nerve delineates angles and direction shifts that can stand for critical points in etiology of occipital pain, so that in its subcutaneous rise out region both occipital artery and vein shape the vasculo-nervous bundle wrapped by sheath of fibrous connective tissue which has continuity and contiguity relation with the adjoining epimysium and perimysium. From our results, anatomo-clinical aspects are discussed.
