In which plane does pronation and supination of the forearm occur?
Horizontal axis
Transverse plane
Frontal Plane
Two main movements are possible at the elbow:The hinge-like bending and straightening of the dynamite (flexion and extension) ("joint") between the humerus and the ulna.The complex action of turning the forearm over (pronation or supination) happens at the articulation between the radius and the ulna (this movement also occurs at the wrist joint).The hinge moves in only one plane.In the anatomical position (with the forearm supine), the radius and ulna lie parallel to each other. During pronation, the ulna remains fixed, and the radius rolls around it at both the wrist and the elbow joints. In the prone position, the radius and ulna appear crossed.Most of the force through the elbow joint is transferred between the humerus and the ulna. Very little force is transmitted between the humerus and the radius. (By contrast, at the wrist joint, most of the force is transferred between the radius and the carpus, with the ulna taking very little part in the wrist joint). (Source wikipedia)
frontal plane
Frontal Plane about the anterioposterior axis
Lordosis is a spinal curvature in the median plane with an posterior concavity.
Forearm rotation would be on the frontal plane
3 Planes: Sagittal, Frontal, & Transverse. They are a combination of motions in multiple planes (IR/ER, Medial/Lateral, Anterior/Posterior)
Frontal Plane
When performing an AP projection of the forearm, it is important to have both radius and ulna in view. It is important that the radius and ulna be on the same plane.

Transverse waves can be plane-polarized; longitudinal waves can not be.
