[Macroscopic-anatomic changes of the skull, spine, spinal cord, extremities and tails of postnatal growing albino rats].

27 albino-rats were used to measure the growth of skull, spinal column, spinal cord, roots of the spinal nerves, and length of tail and extremities at their 1st to the 5th, the 8th, 11th, 15th, and 20th postnatal day. The growth rate of the distal and caudal parts of the distal body was higher than of the cranial and proximal ones.
