GMA Comprehensive Practice Exam

Which are the three primary body planes?

Sagittal and transverse only. Frontal/coronal, transverse, and sagittal. Sagittal (left-right), frontal/coronal (front-back), and transverse (upper-lower). Coronal, horizontal, and transverse.

Correct Answer:

Sagittal (left-right), frontal/coronal (front-back), and transverse (upper-lower).

Explanation:

Three primary body planes form a basic framework for describing location and direction in anatomy: sagittal, frontal (coronal), and transverse. The sagittal plane slices the body into left and right portions. The frontal or coronal plane separates front from back. The transverse plane, also called horizontal, divides the body into upper and lower parts. The answer lists these three planes with their standard orientations: sagittal (left-right), frontal/coronal (front-back), and transverse (upper-lower). Other options either omit a plane or use alternate terms without adding a distinct plane, which can blur the standard three-plane system.
