Bones

Bone serves many important functions. Bones support the body, protect underlying organs, and provide a movable skeleton against which the muscles can work. In addition, bone forms all the cells of the blood, plus takes part in calcium and acid-base balance, and storage of trace elements (such as zinc) needed by cells elsewhere. bone as the most lasting parts of the body, bones are traditionally used for ‘mortal remains’. The longest bone is the femur (thigh bone), which accounts for a quarter of one's stature; the smallest bone is the stapes — one of the tiny ossicles in the middle ear which transmits the vibrations from the ear drum to the inner ear. There are over 200 bones in the adult skeleton. They can be divided into two principal types: the long bones such as the femur, tibia, and humerus, which develop principally from within a cartilaginous framework, and the flat bones such as the skull, bones of the pelvis, and scapula, which develop within membranes of fibrous tissue.

Tennis elbow

Lateral epicondylitis or lateral epicondylalgia, known colloquially as tennis elbow, shooter's elbow, and archer's elbow or simply lateral elbow pain, is a condition where the outer part of the elbow becomes sore and tender. Since the pathogenesis of this condition is still unknown, there is no single agreed name. While the common name "tennis elbow" suggests a strong link to racquet sports, this condition can also be caused by sports such as swimming and climbing, the work of manual workers and waiters, as well as activities of daily living.
