• lies horizontally across the top of the chest 
• reaches from the clavicular notch of the sternum across the top of the shoulder
• articulates with the superior aspect of the scapula
• braces the shoulder anteriorly, preventing the strong chest muscles from pullimg the shoulder towards the sternum
• fractures= fall onto outstretched arm

• large triangular bone that lies flat along the superposterior aspect of the thorax
• consists of a flat body and a dorsal ridge of bone

longest and heaviest of the bones in the upper limb

• on the lateral surface of the scapula
• a shallow crater where the bone of the arm, the humerus, meets the scapula to form the shoulder joint

• bony prominence
• forms a bony bulge at the top of the shoulder, where it articulates with the clavicle to form the acromioclavicular joint

• serves as an attachment point for certain chest and shoulder muscles

• the largest and uppermost bone that fuses to form the coxal bones
• wing-shaped bone that attaches firmly to the sacrum at a scroiliac joint

• roughly mirror image of the ischium
• these two bones meet anteriorly at the symphysis pubis to form a midline bony prominence above the genitalia.
• can separate slightly to allow passage of a baby

• formed when the pubis bones and ischium meet inferiorly and posteriorly 
• large hole in which blood vessels and nerces pass through to reach the anterior thigh

• male= narrow
• female= wide

• a socket into which the bone of the thigh fits to join the lower limb to the pelvis
