Which of the following planes divides the body into anterior and posterior portions?

  1. Sagittal

  2. Transverse

  3. Frontal

  4. Coronal

The correct answer is: Transverse

The plane that divides the body into anterior (front) and posterior (back) portions is known as the coronal plane, which is also often referred to as the frontal plane. This plane runs vertically through the body and allows for the examination of structures in relation to the front and back. The sagittal plane divides the body into left and right portions, while the transverse plane separates the body into superior (upper) and inferior (lower) parts. Each of these planes serves a distinct purpose in anatomical terminology and medical imaging, and understanding their definitions helps in accurately describing the location of structures within the body. The coronal plane specifically emphasizes the directional relationship between the anterior and posterior aspects, making it the correct choice for this question.
