Which term refers to the region that includes the thigh, leg, and groin?

• A. Arm
• B. Forearm
• C. Pelvis
• D. Lower Extremity or Limb

Answer: (D)

Think in terms of limb regions. The region that includes the thigh, leg, and groin is called the lower extremity, also known as the lower limb. In anatomy the body is divided into axial (head, trunk, neck) and appendicular (the limbs). The lower limb extends from the hip to the foot and encompasses the thigh and leg, with the groin marking the junction between trunk and limb. The arm and forearm are parts of the upper limb, not the lower; the pelvis refers to the pelvic girdle at the base of the spine and doesn’t by itself denote the entire limb region. So the correct term for that region is the lower extremity (lower limb).
