Abstract

VARYING statements regarding segmentation of human spinal cord have been made by different writers. They range from “No definite segmentation can, however, be effectively demonstrated. The obvious segmentation of the tube is through the nerve roots which arise in regular sequence from its walls”1 of Paterson to that of Sir Arthur Keith, who states that “Dr. Watt observed in a human embryo in which there are 18 body somites that 11 segments were to be noted in the spinal cord”2.
