Educational content only — not medical advice.

Anatomy

C6, the sixth of seven cervical vertebrae: a small saddle-like body, a large vertebral foramen, and a transverse process perforated by the vertebral artery. Its large anterior tubercle of the transverse process — the carotid tubercle (Chassaignac) — is against which the common carotid artery is compressed to control bleeding.

Clinical notes

Disc herniation at C6–C7 compresses the C7 nerve root, causing arm pain in a characteristic dermatome and weakness pattern.
