Document Summary
V: neck, thorax, abdomen, lower extremity, thigh, leg/shank, foot, upper extremity, arm, forearm, hand. Reference positions: functional position: head forward, feet together, arms at side, palms. Figure 1 facing sides: anatomical position, all movement is described relative to anatomical position, see fig. Inferior: below: anterior: in front of, posterior: behind, medial: toward the midline, lateral: away from the midline, proximal: closer to the trunk, distal: away from the trunk. Planes: plane, two-dimensional structure that can be, anatomical planes (see fig. 2) defined by 3 different points: can extend in all directions, all motion occurs in a plane, sagittal, front/coronal, transverse, planar movements, movement occurs in the plane it runs parallel to. Figure 2: line passing perpendicularly through a plane, motion occurs about an axis, passes through the joint center, longitudinal axis (see fig. 3: anatomical reference axes, transverse plane rotation.
