In the study, 12 (6 females, 6 males) healthy adult New Zealand rabbits were used to examine the morphometrical andstereological values. White matter, gray matter and total segment volume of the segments in the pars lumbalis were calculated byCavalieri’s principle. The findings were grouped according to sexand statistically evaluated. As a result, 38% of the length of the spinalcord in rabbits belonged to the pars lumbalis. The morphometric parameters were not statistically different between male and femalerabbits (p > 0.05). The segment with the biggest volume was L5. White matter’s greatest volume was the L4 segment. The volume of graymatter was enormous in the L6 segment in both genders. When the average volume of lumbal segments was compared according tosex,there was no statistically significant difference (p > 0.05). However, the volume of each segment was greater in male rabbits than infemales. In bothsexes, when the correlation values of the volume were compared with the weight and head-tail length of the rabbit, it wasobserved that this value was not statistically significant (p > 0.05). As a result, this study is thought to be a reference to the researchersto review the neuroanatomy of the lumbal part of the spinal cord in New Zealand rabbits and to localize the neurological studies to beconducted in this type.
