Notochord
Updates to Article Attributes
Body
was changed:
The notochord represents the earliest foetal axial skeleton, and extending from the Rathke's pouch to the coccyx. The notochord which is cylindrical in shape is replaced by sclerotomes that produce cartilage and subsequently bone. The nucleus polposis of the intervertebral discs represent residual notochord.
Vestigial non neoplastic notochordal remnants are seen in up to 2% of cadavers, usually in the midline. They are located:
- spheno-occipital synchondrosis
- sacrococcygeal regions
- smaller scattered foci in the spine (especially C2 and lumbar spine)

- the location of chordomas parallels this distribution
- Thornwaldt cysts are also notochord derived
