Abstract: The study was carried out to elucidate on the macroscopic structure of the medulla oblongata of the grasscutter. A total of ten matured, apparently, healthy African grasscutters were used to investigate the morphologic and morphometric features of the medulla oblongata. The mean body weight and brain weight were 2600±194.95 g and 12.15±0.48 g, respectively. The ratio of the brain to body weight was approximately 1:214. The mean weight of the medulla oblongata was found to be 1.104±0.10 g and this accounted for about 9% of the total brain weight. The mean lengths of the whole brain and medulla oblongata were 4.945±0.091 and 1.376±0.082 cm, respectively. The gross anatomical features of the medulla oblongata were typical of that observed in terrestrial mammals however slight structural differences were observed.
