The document describes the anatomy of the lower limb bones. It discusses the four regions of the lower limb - the thigh, leg, ankle, and foot. It provides details on the bones of the thigh (femur), leg (tibia and fibula), and knee joint. The femur is the longest bone and forms the hip and knee joints. The tibia and fibula form the leg, with the tibia bearing more weight and forming the ankle joint along with the talus bone. Key ligaments like the patellar ligament, collateral ligaments, and cruciate ligaments are described for the knee joint.
