Final answer:
The correct synonym for coronal is D. frontal, which refers to the anatomical plane dividing the body into anterior and posterior portions.
Step-by-step explanation:
The correct synonym for coronal is D. frontal. In anatomical terms, the frontal plane, also known as the coronal plane, is the anatomical plane that divides the body or an organ into anterior (front) and posterior (rear) portions. The term "coronal" is derived from the Latin "corona", meaning "crown", which refers to the plane's orientation, as if crowning the body by running across it from ear to ear. It is important to note that this plane is distinct from the sagittal plane, which divides the body into left and right sections, and the transverse plane, which divides the body into upper and lower sections.
A synonym for coronal is frontal. The frontal plane is the plane that divides the body or an organ into an anterior (front) portion and a posterior (rear) portion. It is often referred to as a coronal plane. The term 'corona' means 'crown' in Latin.
