Formal:
* Coronal section: This is the most precise term for a frontal section, particularly in anatomical contexts.
* Sagittal section: This refers to a cut made parallel to the sagittal suture of the skull, dividing the body into left and right halves.
Less Formal:
* Front view: This is more descriptive, emphasizing the perspective of the section.
* Anterior section: This is a broader term that encompasses any part of the body facing forward.
Other possibilities:
* Transverse section: This refers to a cut that divides the body into upper and lower portions.
* Cross-section: This is a general term for any cut that reveals the internal structure of an object.
Example:
"The researchers studied the frontal section of the brain to analyze the prefrontal cortex."
In this context, "coronal section" would be a more specific and accurate replacement.
