Gross morphological and biometrical Studies on the typical cervical vertebrae of Blue bull (Boselaphus tragocamelus)

Abstract

The present study was carried out on the third (C3), fourth (C4) and fifth (C5) cervical vertebrae of six specimens of adult Blue bull (Boselaphus tragocamelus) of either sex. It was found that the transverse process was bifid with a transverse foramen located at its base. The upper part of the transverse process projected backward and was short and stout, while the lower part was directed downward and forward and was found to be longer and more plate-like. The bodies of C3-C5 tended to become shorter and wider from front to backwards. The supraspinous process was found to be short and centrally tuberous in C3 that gradually increased in height and length to C5 with forward inclination. The articular processes of the typical cervical vertebrae slightly convex cranially and concave caudally. The posterior articular facets of C5 were egg shaped, whereas those of C4 were like the map of Africa in the Blue bull. A well defined infraspinous process projected from the vertebral body that divided the base into two halves. The biometrical observations on different parameters of typical cervical vertebra reflected significance (P less than 0.05) differences between the sexes of this species.

Sex Wise Morphometrical Studies on Orbital Cavity and Foramina of Skull of Adult Blue Bull (Boselaphus tragocamelus)

“…The Blue bull is quite prevalent in northern and central parts of India especially in the foothills of Himalayas, eastern part of Pakistan and southern part of Nepal, but has vanished from Bangladesh (Sathapathy et al, 2019a, Sathapathy et al, 2019band Sathapathy et al, 2019c. The adult male of the Blue bull appears like ox and so called as Blue bull (Sathapathy et al, 2019d andSathapathy et al, 2019e). They are generally seen in day times in the meadow pasture, timberland areas and agricultural land area (Sathapathy et al, 2019f, Sathapathy et al, 2019g and Sathapathy et al, 2019h).…”
