    THE SKELETON. lOI The skull and face are made up of twenty bones, and all, except the lower jaw, are firmly joined together to protect the brain, which is contained in the skull. The spine consists of twenty-six bones, called vertebrae, named according to the region in which they are situated—cervical, or neck ; dorsal, or back ; and lumbar, or loins. There are seven cervical vertebrae, twelve dorsal vertebrae, and five lumbar vertebrae. The two lowest bones are called the sacrum and coccyx. The spine supports the skull and the trunk, and encloses the spinal cord, from which the nerves pass out to the muscles of the body. To each side of the twelve dorsal vertebrae are joined the twelve ribs—the same number in the female and the male. Many of them reach to the sternum (or chest bone) in front, and so form the cavity of the thorax, or chest. The arms are fixed to the top of the sternum by the clavicle, or collar bone, and the scapula, or blade bone of the back. Fixed to the spine below is a hollowed bony cavity, or basin, called the pelvis, to which the legs are attached. The bones of the pelvis are the sacrum and coccyx behind, and the os innominatum (usually divided into the ilium, ischium, and pubes) at each side.
