THE SKELETAL SYSTEM 49 beyond a question as such, shows four complete toes and a sphnt ot a fifth. The hind foot has three toes and a splint.

JOINTS A joint is the union of two or more bones or cartilages. Joints are classified, according to structure, into three types: Type I, immovable, in which the opposed surfaces are directly united by connective tissue, e. g., joints between the bones of the skull. The periosteum also assists in this Fig. 7.—Diagram of section of true joint:/.Z., Fibrous layer; , synovial layer of joint capsule. The articular cartilages are white, bones dotted, and joint cavity black in the figure. (Sisson, Anatomy of Domestic Animals.) Type II, slightly movable, in which the bones are united by cartilage that is elastic enough to permit a slight movement, e. g., the intervertebral joints. Type III, freely movable, in which a joint cavity exists be- tween the opposed surfaces, e. g., hinge-joint, as that of the elbow; and ball-and-socket joint, as that between the pelvis and the femur at the hip. The freely movable joints are the only true joints (Fig. 7). They have the following structures entering into their formation: 1. Two or more bones the joint surfaces of which are usually somewhat expanded. 4.
