Chapter Conclusion

Learning Objectives

• Identify the femur, tibia, and fibula and their anatomical features.
• Identify the bones of the foot and their relative positions.
• Be able to explain the origin, insertion, action, and innervation of the 5 adductor muscles, the knee flexors and extensors, and muscles that move the foot. (not as much emphasis on muscles that move the foot).
• Identify the seven major supporting ligaments of the knee cap. This includes their function and relative positioning.
• Develop a basic understanding of the ligament in the foot, and ligaments associated with the ankle.
• Identify the major blood vessels in this region and what areas these vessels drain/supply blood to.
• Develop a general understanding of the major clinical conditions in this area.
