Answer-7--B)absorb the shock of walking and jumping. The intervertebral discs of the spinal cord are held together by the proteoglycans and glycoproteins which help in the movement of the bones during twisting ,rotation and bending of the body and the degeneration of these vertebral discs lead to decrease and difficulty in walking and locomotion.

Answer--8--C)are found in maxillary,ethmoid and lacrimal bones.
