           B.Endosteal surfaces.

           C.Tendons.

           D. Epiphyseal plates.

           E. The A-band.

  

          5.Connective tissue can be an important source of energy asexemplified by:

            B. Goblet cells.

            C. Pacinian corpuscles.

            D. Pancreatic Acinar cells.  

             E. Macrophages.

        6. The basic bonesubunit, the osteon’s survival depends on a blood supply deliveredvia:

           A. Theosteole.

           B.Mesenteric arterioles.

           C.Radial canaliculi.

           D.Arterioles in the Haversian canals.

           E.Venetian trebecular canals.

         7. The metabolicactivity of trebecular bone is much higher than compact bonebecause:

             A. There are few osteoclasts.

             B. Of abundant osteocytes.

             C. Rapidly dividing erythrocyte progenitors.

8. When challenged by allergenicmaterial, nasal mast cause rhinitis and congestion by:

A. Degrading the nasalepithelium.

B. Releasing norepinephrine toconstrict nasal capillaries.

C. Releasing epinephrine to dilatenasal arterioles.

D. Releasing histamine whichincreases both nasal capillary pressure and permeability.

E. Releases serotonin to disablenasal gap-junctions..

9. Ligaments and tendons are composedof similar materials but tendons transmit force better becausethey:

A. Are less elastic.

B. Have more fibroblasts.

C. Have more elastic fibers.

D. Have fewer macrophages.
