SUMMARY
The objective of the present work was to study the cerebral ventricles and its associated parts of brain of Surti buffalo (n=12), The cerebral ventricles included two lateral ventricles and third ventricle. The lateral ventricles were curved cavities presented large central part and three horns within the cerebral hemispheres. The third ventricle was an annular space on the periphery of inter-thalamic adhesion between two thalami. The mean length and width of central part of lateral ventricle were 4.78±0.07 and 1.49±0.07 cm, respectively. The septum pellucidum was thin translucent membrane of two laminae which separates two lateral ventricles. The mean values of length and height of septum pellucidum were 3.6±0.12 and 0.52±0.04 cm, respectively. The cavum septum pellucidum was a small space found between two laminae of septum pellucidum.
