Vertigo- A conflict between the signals sent to the brain by your balance and the position-sensing systems in your body are what cause dizzy spells that are best described as vertigo. Vision, sensory nerves and skin pressure are the three main sources of information input that your brain uses to balance your body.
Bison are large, even-toed ungulates in the genus Bison within the subfamily Bovinae. Two extant and six extinct species are recognised. Of the six extinct species, five went extinct in the Quaternary extinction event. Bison palaeosinensis evolved in the Early Pleistocene in South Asia, and was the evolutionary ancestor of B. priscus (steppe bison), which was the ancestor of all other Bison species.
The Gaur or Indian Bison is a large endangered herbivore, and can be seen in protected sanctuaries in India.n the wild its young are preyed upon by tigers and leopards and the loss of its habitat due to human encroachment has led to the reduction in its population across India. In North East India a tame version of the Gaur, known as Mithun is used as a farm animal and is sacrificed and eaten at ritual feasts.
