Question

A person is reaching forward and upward into a cabinet. In which plane and around which axis does this movement primarily occur?

A. Transverse plane around a sagittal axis
B. Sagittal plane around a frontal axis
C. Frontal plane around a vertical axis
D. Horizontal plane around a sagittal axis

Answer 1

Reaching forward and upward into a cabinet occurs in the sagittal plane around the frontal axis, due to the nature of flexion and extension motions involved in such an action.

Step-by-step explanation:

The movement of reaching forward and upward into a cabinet primarily occurs in the sagittal plane and around the frontal axis.

This is because the sagittal plane divides the body into left and right portions and is associated with flexion and extension motions. Such movements are typical when reaching forward (flexion) and then extending the arm upward.

Moreover, these movements take place at the shoulder, which involves both flexion as reaching forward and then extension when lifting the arm upward.

The reference to an axis around which the movement primarily occurs indicates the movement involves rotations; thus, the relevant axis is perpendicular to the sagittal plane, i.e., the frontal axis.

Answer 2

The movement of reaching forward and upward into a cabinet occurs primarily in the sagittal plane around a frontal axis. Option B. Sagittal plane around a frontal axis is the correct answer.

Step-by-step explanation:

When a person is reaching forward and upward into a cabinet, the primary movement occurs in the sagittal plane around a frontal axis.

This movement involves flexion and extension, which are typical motions within the sagittal plane. In more detail, the sagittal plane divides the body into right and left portions and is involved when there is an anterior or posterior movement of the body or limbs, such as reaching forward.

The frontal or coronal axis, which is perpendicular to the sagittal plane, serves as the axis of rotation for these movements. Hence, when reaching upward and forward, the shoulders and arms flex and extend within this plane and revolve around the frontal axis.

Therefore, the correct option is B. Sagittal plane around a frontal axis.
