Fascia lata muscle. This band is continued downward under the name of the iliotibial band and is attached to the lateral condyle of the tibia. The part of the iliotibial band which lies beneath the tensor fasciae latae is prolonged upward to join the lateral part of the capsule of the hip joint. Below, the fascia lata is attached to all the prominent points around the knee joint, viz., the condyles of the femur and tibia, and the head of the fibula. On either side of the kneecap it is strengthened by transverse fibers from the lower parts of the vasti muscles
Vertical clinging and leaping phalangeal index, low intermembral index, femurs with cylindrical head and high, narrow patellar grooves, and fused fibula and tibia. The high phalangeal index is the elongation of the phalangeal finger bones, which helps vertical clingers who require increased prehensile power in their hands to support their large bulk. The low intermebral index is the total length of the humerus and radius in percentage of total length of the femur and tibia. The features of the femur is part of an evolution of elongated femurs that helps the primates' extreme range of flexion and extension, which allows them to perform their
