Human leg in a straight line, which represents the mechanical longitudinal axis of the leg, the Mikulicz line. This line stretches from the hip joint (or more precisely the head of the femur), through the knee joint (the intercondylar eminence of the tibia), and down to the center of the ankle (the ankle mortise, the fork-like grip between the medial and lateral malleoli). In the tibial shaft, the mechanical and anatomical axes coincide, but in the femoral shaft they diverge 6°, resulting in the "femorotibial angle" of 174° in a leg with normal axial alignment. A leg is considered straight when, with
Limbs of the horse limb of the horse runs from the pelvis to the navicular bone. After the pelvis come the femur (thigh), patella, stifle joint, tibia, fibula, tarsal (hock) bone and joint, large metatarsal (cannon) and small metatarsal (splint) bones. Below these, the arrangement of sesamoid and phalanx bones and joints is the same as in the forelimbs. When the horse is moving, the distal interphalangeal joint (coffin joint) has the highest amount of stresses applied to it of any joint in the body, and it can be significantly affected by trimming and shoeing techniques. Although having a small range of movement, the
