Objective: study of anatomical position of termination of the spinal cord in male cat
Animals: fifteen male cat in 2 prenatal groups of mid stage fetus [37d] and late stage fetus and 3 postnatal groups of newbom, sexually adult [6 m] and adult age [>ly/o] and 3 animals in each group
Procedure: fixation of spinal cord with injection of and suspension in 10% formalin, laminectomy of vertebral column and definition of spinal cone on related to vertebral column by pin
Results: the results indicated that, as in the mid and late stage fetuses, the spinal cord terminated at anterior one third of Co, and posterior one thud of S,, respectively but in newbom, sexually adult stage and adult age at posterior, middle and anterior one third of S2, respectively
Discution: thus with increase of age the terminal portion of spinal cord were more anterior and this showed that the vertebral column had been grown faster than that the spinal cord
