The Pectoral (or Shoulder) Girdle Figure 8.1:

Clavicle L or R? :

Clavicle L or R? Top has to be flat Find the “bump” near one end, turn the bone so that the “bump” faces the floor. Turn bone so that the “bump” is TOWARD YOU (so you can see it). Move the bone to the side of the body so that the “bump” is lateral.

Scapula: L or R:

Scapula: L or R Put the smooth surface against the chest on the front so that projections face the shoulder. The bone belongs on the “opposite” side when placed on the back. The glenoid cavity must be on the lateral side

Humerus:

Humerus Find the bicipital groove (blue paint). Rotate so that it faces anteriorly, the head should touch the shoulder (be medial). Olecranon fossa should be posterior. (this articulates with the olecranon of the ulna.)

Humerus and Glenohumeral Joint Figure 8.4:

Ulna:

Ulna This bone has a “u” at one end (Trochlear notch). Make sure that the “u” faces superior (is up). Place the “U” in palm of the hand that faces “up” (superior) and the thumb should rest in the radial notch. The little projection at the other end should be on the same side of the hand as the little finger. Ulna is on the medial aspect of the forearm.

Right ulna and radius in relation to the humerus and carpals -- Figure 8.6:

Radius:

Radius The bone has a round end (the head). There is a bump (radial tuberosity), this should be “up” and the thumb should rest in the radial notch. There is a little projection at the other end should be on the same side of the hand as the little finger.

Right Lower Limb Figure 8.12:

Femur :

Femur The head (rounded end) should be near the hip (medial) and the smooth surface (patellar surface ) at the other end should be forward (anterior)

Patella Figure 8.14:

Patella:

Patella Lay the bone on the table so that the “pointed” end is away from you. Try to tip it by touching the bone. The side it falls to or lays on is the side on which it belongs. If you keep tapping it, it will “walk” or move to the side on which it belongs.

Tibia and Fibula Figure 8.15:

Tibia:

Tibia The large end should be near the knee The bump(tibial tuberosity) should face forward and the groove (fibular notch) should be lateral with the large bump (medial maleolus) should be medial (sharp end in the front). Tibia is medial to the fibula

Tibia and Fibula Figure 8.15:

Fibula:

Fibula Flatter end should face the floor Find the end with a small depression (lateral maleolus ). This end should be near the ankle. The depression should be medial and on the posterior half of the bone. Hold the bone in either your left or right hand held to your side. When looking at the small depression, if it is on the posterior half of the bone it is on the correct side. If it is on the anterior half, it is on the wrong side of the body; try switching hands and look again. The depression should now be on the posterior half.
