The coxal region is lateral to the umbilical region.
Explanation: The term ‘coxal’ refers to the area around the hip, while ‘umbilical’ pertains to the area around the navel. In anatomical terms, ‘lateral’ indicates a position that is further from the midline of the body. Therefore, when comparing the two regions, the coxal region is situated to the side (or lateral) of the umbilical region.
