    The phalanges (Gr. phalanx, a line of soldiers ; a rank) of the fingers are united to the metacarpal bones. There are three of these in each finger and two in the thumb, making a total of fourteen for each hand. The bones of the lower extremities are :— The bones of the calf. Pelvic or hip hones. Femur or thigh-bone. '' Patella or knee-cap. Tibia or shin-bone. Fibula or splint-bone. Tarsal or a?ikle-bones. Metatarsal or instep-bones. Phalanges or toe-bones. The pelvic or hip-bones are also called the ossa innominata or innominate bones (Lat. in, not : and nomen, a name). If we Fig. 33.—Pelvis and Sacrum, seen from before. I, sacrum ; 2, ilium; 3, ischium ; 4, pubis ; s, acetabulum. examine these in the skeleton of a young child, we find that each os innominatwn is composed of three distinct parts, which meet at a deep cup-like depression called the acetabulum (Lat., a cup for holding vinegar). The broad upper portion is called the ilium (Gr. eileo, I twist); the lower part, the ischium (Gr. ischion, the hip); and that portion which is joined to the other innominate bone, the pubis. The acetabulum receives the rounded head of the thigh bone. The bones of the pelvis are supported like a bridge on the legs as pillars, and serve in turn as a support for the internal organs of the abdomen or lower part of the trunk.
