It is hidden medially and superiorly to each occipital condyle. At this point, the secondary axon leaves its nucleus and passes anteriorly and medially. Stress on the hip causes the epiphysis to move posteriorly and medially. Thus, the lateral fusiform gyrus is delineated by the OTS laterally and the MFS medially. Likewise, the medial fusiform gyrus is delineated by the MFS laterally and the CoS medially. Whether it acts to rotate the femur laterally or medially is dependent on position. Fingers and toes may also be abnormally short and laterally or medially bent. It is biconcave in structure and attaches to the condyle medially and laterally. Thorax dorsally with at least one yellow patch medially between wing-bases. Medial peritalar subluxation can be demonstrated by a medially rotated talonavicular coverage angle. It is directed lateral and medially and slightly posterior. They work to adduct and medially, or internally, rotate the humerus. Popliteus flexes the knee joint and medially rotates the leg. Lower lip pits may also be bilaterally, unilaterally, or medially asymmetrical. It acts to flex the tarsus and rotate the paw medially.
