THE LOWER EPIPHYSIS OF THE FEMUR 405 The upper epiphysis of the humerus is composed of threeseparate centers of ossification : That for the head, appearingat two years ; that for the great tuberosity, appearing at threeyears ; that for the lesser tuberosity, appearing at four three centers coalesce to form the upper epiphysis, andit unites, at from the twentieth to the twenty-fourth year, to thediaphysis of the humerus (see Fig. 568). (For Separation ofthis Epiphysis see p. 128.). Fig. 571.—Relation of the capsule of the knee-joint to the lower epiphysis of the femur and theupper epiphysis of the tibia (diagram).
