Tendons attach the knee muscles to the bone. Here’s a labelled knee diagram to see how everything fits together: If you want to learn more about the anatomy of the knee joint, including its complex range of motion (flexion, extension, rotation, and the knee’s terminal locking mechanism), simply take a look at the following resources! Running parallel to the tibia is the fibula, the thinner and weaker bone of the lower leg. Other sesamoid bones could be found in the tendons of the hand and foot finger's flexor muscles at the regions of the higher bending and friction stress. Nicola McLaren MSc “I would honestly say that Kenhub cut my study time in half.” Contraction of the quadriceps group extends the leg at the knee and flexes the thigh at the hip.

The posterior accessory GSV of the leg (Leonardo's vein or posterior arch vein) is a common tributary, it begins posterior to the medial malleolus, ascends on the posteromedial aspect of the calf, and joins the GSV distal to the knee (see Figure 2.8). In some books and videos, you may find that the lower limb is referred to as the leg, which is not entirely accurate. It also allows for rotation and pivoting. These include the sartorius and the four muscles of the quadriceps femoris (rectus femoris, vastus medialis, intermedius, and lateralis), all of which extend the leg at the knee joint. However, the fibula function is more nuanced - it plays a secondary role in the articulation of the ankle joint, facilitating its movement, and provides the proximal attachment point for a number of muscles. Both of these nerves ca… They receive innervation via the femoral nerve (the neurovasculature of the lower extremity can be a daunting task, but we're here to help you out!).
