Major nerve trunks (Trunci nervorum majores)
Educational content only — not medical advice.
Anatomy
A merged group uniting the major nerve trunks, the principal cranial nerves and the nerve ganglia as supplied by the BodyParts3D model into a single structure, showing the great pathways that carry motor commands and sensation between the brain, spinal cord and every organ of the body, together with the relay stations (ganglia) along their course. Note that this representation is merged: the source provides no individually named nerve or trunk meshes.
Clinical notes
Injury to a major trunk produces a deficit far beyond any single nerve: motor and sensory loss across everything that trunk supplies, as in brachial-plexus palsy after birth traction or motorcycle accidents, or hemiplegia after a cortical stroke. Any mass compressing a major trunk — mediastinal tumours, vertebral fractures — causes a progressive deficit demanding urgent imaging.
