Answer 1

ANSWERS

   47. E.Choice A and B ( conduct or propogate electrical activity and secretes neurotransmitters.

    48. B. The cerebral hemispheres are joined toghether by the corpus callosum.

    49. D.All of the above (ventromedial nucleus is the feeding center,ventrolateral nucleus responsible

             for thermoregulation,hypothalamic obesity involves lesion in the satiety center.)

   50.B. Fibers from the cranial nerves 3,4,5 gives rise to the nerve that innervates the diaphragm.

     51.C.Osteoclast cells are responsible for calcium homeostasis.

     52. B. False.Osteolysis is not the function of osteoclasts.they are responsible for bone resorption

               but excessive activity of osteoclasts due to pathogenesis leads to osteolytic disorders.

     53.A.True.Zone of provisional calcification also known as epiphyseal growth plate.

     54.A.True.Fracture or dislocation that has an adverse impact on the vascular integrity of subcapital

                      or surgical neck of the femur can lead to osteonecrosis.
