Explanation / Answer

32. There are 12 pairs of cranial nerves and 31 pair of spinal nerve. Hence, b is correct

34. Vestibulocochlear is not purely sensory. Hence, d is correct.

35. Longitudinal fissure separate right and left cerebral hemisphere

36.A positive Babinski sign indicate damage to pyramidial motor tract. This is true statement. Hence, b is true.

37. The corpus callosum connect right and left cerebral hemisphere. Hence, a is correct.

38. Primary motor is located on prefrontal cortex. Hence, b is correct.

39. Same as question no. 35
