What anatomical plane divides the body into anterior and posterior portions?

• A. Transverse plane
• B. Frontal plane
• C. Sagittal plane
• D. Oblique plane

Answer: (B)

The frontal plane, also known as the coronal plane, divides the body into anterior (front) and posterior (back) sections. This anatomical plane runs vertically from side to side and allows for observations of the body from a front view or back view. It is particularly useful for understanding the arrangement of structures that are located at the front (like the chest and stomach) compared to those at the back (like the back muscles and spine). In contrast, the transverse plane cuts across the body horizontally, separating it into upper and lower parts, while the sagittal plane divides the body into left and right sections. The oblique plane is not a standard anatomical term and refers generally to any diagonal cut through the body, making it less applicable for this specific question regarding the anterior and posterior division. Thus, the frontal plane is the correct choice as it specifically aligns with the classification of body portions into front and back.
