Human skeleton, the internal skeleton that serves as a framework for the body. This framework consists of many individual bones and cartilages. There also are bands of fibrous connective tissue—the ligaments and the tendons—in intimate relationship wit
Femur, upper bone of the leg or hind leg. The head forms a ball-and-socket joint with the hip (at the acetabulum), being held in place by a ligament within the socket and by strong surrounding ligaments. In humans the neck of the femur connects the shaft
protected by the skull, which is composed of the cranium and the bones of the face. Layers of tissue between the cranium and brain cover the brain anatomy, which is cushioned by a clear liquid called cerebrospinal fluid. The brain anatomy is discussed in more detail in the following sections...

such extracellular materials as hair and nails are composed of protein. So also iscollagen, the fibrous, elastic material that makes up much of the body’s skin, bones, tendons, and ligaments. Proteins also perform numerous functional roles in the body. Particularly important are cellular proteins...
The larynx, or voice box, enlarges, with resultant deepening of the voice. Certain features in the skeleton, as seen in the pelvic bones and skull, become accentuated. The hair in the armpits and the pubic hair becomes abundant and thicker. Facial hair develops, as well as hair on the ...
