Phil is a full-size skeleton with joint system model. Demonstrate internal and external rotation of the limbs and show how the knee and elbow joints move and stretch. The flexible spine can make natural movements (lateral bend, movement and stretching, rotation). The hand bones of this skeleton model have been assembled on wire to show their natural position. The flexible assembly of the foot bones makes them maneuverable. The shoulder blades twist when the arms are raised. Even the low level of maneuverability of the sacroiliac joint and the sacrococcygeal symphysis can be demonstrated. Used in hospitals, schools, universities, and laboratories. The skeleton is ideal for active use in teaching and demonstrations. The skeleton is on a metal hanging roller stand (painted white). Measures at: 75.8" and 21.1 lb. Features: 3-part skull, individually inserted teeth, removable arms and legs, natural cast, transparent dust cover and 3 year guarantee.
