Intervertebral Disc
Derivative: nucleus pulposus of the intervertebral disc.
What our notes say
- Derivative: nucleus pulposus of the intervertebral disc. (Aponeurosis — Embryology Question Bank)
- Two fates of B (notochord): mostly regresses; the remnant persists as the nucleus pulposus of the intervertebral disc (Aponeurosis — Embryology Question Bank)
- Found in articular discs, symphyses, intervertebral discs, and tendon-to-bone attachments; resists compression and tensile stress (Aponeurosis — Histology Question Bank)
- Three sites where found: knee menisci; intervertebral discs; pubic symphysis (Aponeurosis — Histology Question Bank)
- Q92: Outline four actions of the intervertebral disc, A (4 marks) (Aponeurosis — Anatomy Question Bank)
- 40% of cases involve the spine (Pott disease) — infection crosses intervertebral discs, destroys vertebrae + soft tissue → compression fractures → scoliosis, kyphosis, neurologic deficits (Bone & Joint Pathology: Basic Structure, Cells, and Fractures)
