Lumbar Vertebra.—The vertebrae of the Loins, or the Lumbar, are five in number, and are the largest members of the spinal column, since they are the only bones in this part of the body. They are more massive and solid in all their parts than the rest of this column, that they may be equal to the strength required of them. 101. Sacrum.—The Sacrum is a single bone, although its typical form is that of five vertebrae, which are actually found in some animals. Its appearance is that of five verte- brae, which are partially anchylosed or grown together. The form of the bone is somewhat like a wedge, with the base directed upwards, and the point curving inwards and for- wards. Fig. 43. 102. Coccyx.—The Coccyx is the lower extremity of the Spinal Column, formed of four anchylosed and imperfect verte- brae ; and it is an extension of these bones
