Which section is commonly known as the coronal section?

The correct choice is the frontal section, which is commonly referred to as the coronal section. This terminology stems from its anatomical orientation, where the frontal section divides the body into anterior (front) and posterior (back) parts. In practice, this means that when a body is sectioned coronally, you can clearly see the structures in the front of the body and those towards the back.

This understanding is important for visualizing anatomical relationships and for surgical planning, as it gives insights about the location of organs, tissues, and essential structures from a front-back perspective. Recognizing this distinction helps in comprehending other anatomical planes and their functions in medical assessments or procedures.

The other choices pertain to different anatomical sections: the sagittal section divides the body into left and right parts, the transverse section (also known as a horizontal section) divides the body into superior (upper) and inferior (lower) halves, and the dorsal section relates to the back side of the body. Understanding these distinctions solidifies a foundational knowledge in anatomy that is crucial for nursing practice.
