Document Summary

Amphiarthrotic joint with bones connected by a ligament. Distal and proximal portion will move, but little move in the middle, where the interosseous membrane connects two bones. Example - growth plate in long bones; joints in between the ribs and sternum. Amphiarthrotic joint where articulating bones separated by pad of fibrocartilage. Example - joint between the two pubic bones (pubic symphysis: cartilaginous, synchondrosis, symphysis, bony, synostosis, synovial. Synarthrotic, totally rigid, immovable joint - some movement but very little. Dorsiflexion - upward movement of the foot or toes; decreasing angle between top of foot and the leg/tibia; top of the foot is called the dorsimum; moving dorsimum of the foot back. Medial/internal rotation - anterior surface of a limb turns toward the long axis of the trunk. Lateral/external rotation - anterior surface of a limb turns away from the long axis of the trunk. Special for forearm rotation; movement occurs at proximal joint between radius and ulna; radial head rotates.
