Give specific character of pneumatic bones |
|
Answer» The bones of BIRDS are lighter in weight than those of MAMMALS. Some of the bones are hollow and actually act as part of the avian respiratory system. These bones, called PNEUMATIC bones, include the skull, humerus, CLAVICLE, keel, pelvic girdle, and lumbar and sacral vertebrae.Pneumatic Bones have air spaces within them which makes them lighter than more solid BONE. They are only found in the skull. |
