Procedure Cexamples Of Synovial Joints

1. Study and compare the shoulder, elbow, hip, and knee joints in figures 17.1, 17.2, 17.3, 17.4, and 17.5.

2. Examine models of the shoulder, elbow, hip, and knee joints. Locate as many features as possible on the models that are illustrated in figures 17.1 through 17.5.

3. Complete Part E of the laboratory report.

DEMONSTRATION

S tudy the available radiographs of joints by holding the films in front of a light source. Identify the type of joint and the bones incorporated in the joint. Also identify other major features that are visible.
