HISTOMORPHOLOGICAL STUDIES ON THE MOTOR DIVISION OF OCULOMOTOR NUCLEUS IN THE BUFFALO (Bubalus bubalis)*

The morphology of the motor divisionof oculomotor nucleus in the buffalo has been described by materials collected from eight buffalos. Myelin stained serial and semi serial sections of brain stem were used for the study. The motor nucleus of oculomotor nerve was located ventral to the cerebral aqueduct in a wedge shaped trough formed by the medial longitudinal fasciculus. It extended from the level of junction of the rostral and caudal colliculi to the cranial third of the rostral colliculus. The average length, width and height of the motor nucleus in the buffalo were 8.1mm, 1.75mm and 2.75mm respectively. The motor nucleus in the buffalo was subdivided into a caudal central, dorsomedial, dorsolateral and ventral divisions.
