Our upper limbs are free, mobile, and adapted for prehension. Each articulates with the trunk at the sternoclavicular joint. Our lower limbs have to bear the weight of the body when walking, runnning, jumping, or standing. They are united behind to the vertebral column at the sacroiliac joints and in front to each other at the symphysis pubis. ‘The limbs’ describes the anatomy of the upper limb—divided into the arm between shoulder and elbow; the forearm between elbow and wrist; and the hand below the wrist—and the lower limb, which is divided into the thigh between hip and knee; the leg between knee and ankle; and the foot below the ankle.
