Abstract
Regional growth of spinal cord and vertebral column during the prenatal development of goatwas studied using 52 foetuses of various ages. The maximum and minimum regional spinal cordlength was measured in the thoracic and coccygeal regions, respectively. A highly significantpositive correlation was observed between total cord length and length of different cord regionsexcept coccygeal region. Regional length of the vertebral column was dependant on the regionallength of the spinal cord except at the coccygeal region and changed accordingly. The thoracicregion of spinal cord exhibited an increased growth rate over that of vertebral column during secondand third month. Cervical and lumbar spinal cord regions showed isometric growth rate withcorresponding vertebral column regions during all stages. The sacral region also was isometric uptofourth month, which declined in the fifth month.
