Identify the muscles indicated in figure 25.12.  Sartorius Vastus Medialis Rectus Femoris Gastrocnemius Vastus medialis Tibialis Anterior Vastus Lateralis Soleus FIGURE 25.12 Label these muscles that appear as lower limb surface features in these photographs (a) and (b), by placing the correct numbers in  the spaces provided. A1 ©J & J Photography 2. Wesley tore his calcaneal tendon playing a pick-up game of basketball. What two muscles of the leg would be directly affected by this injury, and what would be the immediate consequence in Wesley’s mobility? Explain. ________________ The solus and gastroceminus, he would have a hard time walking without the use of these muscles because he would be virtually unable to flex his knee.. A2 A3
