| The architecture of cranial and non-cranial nerve nuclei in the medulla oblongata of the African giant pouched rat was studied by means of light microscopy. Serial sections of the medulla oblongata, in coronal and saggital planes, were stained with the cresyl fast violet and silver stains, respectively. Sections in the saggital plane were used as a guide, while coronal sections were used to identify the nuclei in the rostrocaudal extent of the medulla oblongata. With the obex serving as the landmark, nuclei rostral and caudal to the obex were delineated. Cranial nerve nuclei whose architecture were defined were the motor nucleus of hypoglossal nerve, motor nucleus of vagus nerve, cochlear nucleus, vestibular nucleus and nucleus ambiguus, while non-cranial... |

| A qualitative and quantitative study, by light microscopy, was undertaken on the lower respiratory system of the African Giant pouched rat. Specifically, the trachea, bronchi and lungs were stained with Haematoxylin and eosin, Alcian blue at a pH of 2.5 and Periodic Acid-Schiff stains. Three cell types were identified in saggital sections of the trachea: the ciliated cells, basal cells and mucous cells. Fibers of the trachealis muscles in the laminar propria separated the underlying cartilages from the basal cells. Mucous cells were visible only in the membranous portion of the trachea and they were predominant in the rostral and caudal portion of the trachea. Lobar bronchi consisted of cuboidal epithelium and a layer of one or two smooth muscle cells and... |

| A morphometric study was undertaken on the long bones in the two predominant breeds of small ruminant in Northern Guinea Savanna zone of Nigeria, to determine their anatomical differences and thus, provide a means of differentiating the remains of these two species during zooarchaeological studies and gross anatomy practical session. The pelvic and pectoral limbs from thirty animals (15 Yankasa sheep and 15 Red Sokoto goats) of both sexes were used for this study. The long bones of the pectoral limbs considered were the humerus, radius, ulna and metacarpal III while those of the pelvic limbs were the femur, tibia and metatarsal III. The parameters considered were the mean weights, lengths and diameters of the proximal extremity, mid-shaft and distal... |
