ABSTRACT
The ultrastructural organization of the seminiferous tubules of the camel has been investigated using transmission microscopy. The boundary tissue comprised four distinct layers; 1] an inner non-cellular layer, made up of two amorphous lamellae of moderate electron density sandwitching a layer of collagenous fibrils; 2] an inner cellular layer comprising stacks of extremely long spindleishaped peritubular cells showing a considerable proportion of microfilaments and micropinocytotic vesicle, 3]- an outer fibrous layer containing bundles of collagenous fibrils filling the spaces between lymph and blood capillaries. The latter showed the existance of distinct gaps between their endothelial lining and they missed basal laminae of their own, 4]- an outer cellular layer made almost exclusively of attenuated fibrocytes with minimal fibrous content

This work was carried out on four limbs of adult normal buffalos in addition to those of ten slink calves. The vertebral canal and the spinal meninges were exposed to demonstrate the root fibers of each nerve. The course and distribution of each nerve were traced as far as its gross terminal ramifications. The results obtained were discussed with the findings recorded by other authors on various domestic animals

The present investigation was conducted on 20 full grown camel fetuses. This study investigated in situ 20 spleens of adult healthy camels in addition to the inspection of the spleens of 30 slaughtered adult healthy camels. The position, relation, fixation and gross anatomical features of the spleen were thoroughly investigated. The vascular pattern of the spleen was studied by the ordinary routine method, radiologically as well as by using cast forming material. The arterial segmentation of the spleen of the camel revealed three arterial
