GROSS STUDIES ON THE LUMBAR VERTEBRAE IN BLUE BULL (BOSELAPHUS TRAGOCAMELUS).

The present study had been conducted on the lumbar vertebrae of blue bull. There were six lumbar vertebrae. The transverse processes were spreading out laterally and slightly bent forward. The length of the first transverse process was the shortest and straight, which gradually increased up to the last. The width of last two processes was less than the same of first four vertebrae. The height of spinous process decreased gradually from first to the last. The mammillary processes of lumbar vertebrae were fused with the anterior articular processes, which were thick and tuberous. In the last lumbar vertebra, the body was compressed from above downwards and the neural ring was widest. The articular processes were placed wide apart from body. The interarcuate spaces were gradually increased from the fourth-fifth lumbar and sixth lumbar-sacrum vertebra. [ABSTRACT FROM AUTHOR]
