Work Step by Step
The inguinal region is medial to the coxal region. The coxal region is defined as the area around the hip. The inguinal region is the groin region. The groin region is more in the middle of the body (medial) than the hips.
Answer B is incorrect because hypochondriac means "a person who has an obsession with the idea of having a serious, but undiagnosed medical condition".
Answer C is incorrect because umbilical means belly button and while the umbilical region is more medial than the coxal region, it is also more superior (higher up).
Answer D is incorrect because popliteal means the dorsal side of the knees, which is inferior to the coxal region.
Answer E is incorrect because cubital means ventral side of the elbow, which is superior to the coxal region.
