| The longest bone of the upper limb | The Humerus |
| Proximal end of the humerus that fits into the glenoid cavity of the scapula | Head of the Humerus |
| Medial condyle of the humerus that articulates with the ulna | Trochlea |
| Lateral condyle of the humerus that articulates with the radius | Capitulum |
| Part of the humerus that receives the olecranon process | Olecranon Fossa |
| Part of the humerus that receives the coronoid process | Coronoid Fossa |
| The projection of the ulna that fits into the olecranon fossa when the arm s fully extended | Olecranon Process |
| The projection of the ulna that fits into the coronoid fossa when the arm is flexed | Coronoid Process |
| Structure located on the distal end of the radius and receives the head of the ulna | Radioulnar Joint |
| Bone(s) of the hand | Carpals, Metacarpals, Phalanges |
| Functions of the pelvic girdle (2) | Attaches lower limbs to the spine, Supports visceral organs |
| A deep structure of the pelvic girdle that holds the head of the femur | Acetabulum |
| Superior region of the coxal bone, Large, flaring bone | Ilium |
| Posteroinferior region of the coxal bone | Ischium |
| Anterior region of the coxal bone | Pubis |
| The two pubic bones joined by fibrocartilage at the midline | Pubic Symphysis |
| The large hole between the pubis and ischium | Obturator Foramen |
| Bone(s) of the thigh | Femur |
| Bone(s) of the knee | Patella |
| Bone(s) of the Leg | Tibia and Fibula |
| Longest and strongest bone in the body | Femur |
| Membrane that connects the tibia and fibula | Interosseous Membrane |
