Appendicular skeleton | The 126 bones that form the appendages to the axial skeleton; the upper and lower extremities |
Skull | Made up of 28 bones in two major divisions: cranial bones and facial bones |
Upper Extremity | Consists of the bones of the shoulder girdle, upper and lower parts of the arm, wrist, and hand |
Lower Extremity | Consists of the bones of the hip, thigh, leg, ankle, and foot |
Fibrous joints (synarthroses) | Bones of joints fit together closely, thereby allowing little or no movement |
Cartilaginous joints (amphiarthroses) | Bones of joints are joined together by hyaline cartilage or fibrocartilage; allow very little motion |
Hinge joints | articulating ends of bones form a hinge-shaped unity that allows only flexion and extension |
Range of motion (ROM) | Assessment used to determine extent of joint injury |
Flexion | Decreases the angle between bones; bends or folds one part on another |
