Anatomy

C5, the fifth of seven cervical vertebrae: a small saddle-like body, a large vertebral foramen, and a transverse process perforated by the vertebral artery. Its canal is relatively roomy, cushioning cord oedema; the C5–C6 disc below is among the most frequently herniated in the neck.

Clinical notes

Disc herniation at C5–C6 compresses the C6 nerve root, causing arm pain in a characteristic dermatome and weakness pattern.
