Final answer:
In the frontal plane, the key movements are abduction and adduction, including the lateral bending of the spine, as well as specific movements such as the elevation and depression of the scapula.
Step-by-step explanation:
Movements that occur in the frontal plane (also known as the coronal plane) typically involve actions that move parts of the body along a lateral axis. In particular, these movements include abduction and adduction. Abduction refers to moving a limb or appendage away from the midline of the body, such as when you raise your arms to the side or spread your fingers or toes. Conversely, adduction is the movement toward the body's midline, like when lowering your arms to your sides or bringing your fingers together.
In addition to abduction and adduction, other movements in the frontal plane include lateral spinal flexion, where the spine bends side-to-side, and some special movements of the scapula and other parts that can elevate, depress, protract, or retract in this plane. The frontal plane divides the body into anterior and posterior sections, and the movements within this plane are essential to our daily activities and athletic endeavors, offering a wide range of motion and flexibility.
