Question

The _____ region of the left lower limb is proximal to the _____ region of the same limb

Answer 1

Answer: femoral; crural

In referring location/region you can use proximal or distal. Proximal means closer to the body. It's the opposite of distal that would mean further to the body
Femoral (or thigh) is located nearer to the body than crural (or leg).
