Appendicular Skeleton Developmental Regions
The developing limb can be described along the proximodistal axis as having three main regions, with abnormalities along this axis characterised by the changes to these specific skeletal components.
Stylopod
The proximal region the limb, the skeletal component of the upper limb (forelimb) is the humerus, and for the lower limb (hindlimb) is the femur.
Zeugopod
The mid-section of the limb , the skeletal components of the upper limb (forelimb) are the radius and ulna, and for the lower limb (hindlimb) are the tibia and fibula.
Autopod
The distal region the limb, the musculoskeletal component of the upper limb (forelimb) is the hands, and for the lower limb (hindlimb) is the foot.
Axial Terms
Preaxial
(before an axis) portion of limb bud that lies cranial to the axis of the limb, refers to the lateral (radial) aspect of the upper limb, and the medial (tibial) aspect of the lower limb.
portion of a limb bud that lies cranial to the axis of the limb: the radial aspect of the upper limb and the tibial aspect of the lower limb.
Postaxial
(behind an axis) portion of limb bud that lies caudal to the axis of the limb, refers to the medial (ulnar) aspect of the upper limb, and the lateral (fibular) aspect of the lower limb.
