Human Functions Test 1 Practice

Abduction and adduction happen in the coronal (frontal) plane. This plane divides the body into front and back portions, and movements that move a limb away from or toward the midline occur within it. For example, lifting the arm out to the side is abduction in this plane, and bringing the arm back toward the body is adduction. In contrast, flexion and extension mainly occur in the sagittal plane, and rotation occurs in the transverse plane. So the coronal/frontal plane is the one primarily associated with abduction and adduction.
