Gurnick Academy Anatomy Practice Test

The transverse plane runs horizontally, perpendicular to the body's long axis, and divides the body into upper (superior) and lower (inferior) portions. It’s the plane used to create cross-sections that show what’s above and below that level. The other planes cut left from right (sagittal), front from back (frontal/coronal), or are slanted (oblique), so they don’t specifically separate superior and inferior parts.
