go THE SKELETON OF THE CAT. 



ment (Fig. 60, h\ Fig. 61, d), begins on the tibia at the edge 

 of the popliteal notch (Fig. 61, d), nearer the medial side, and 

 passes dorsad and proximad to be attached to the ventral edge 

 of the patellar surface of the femur, in the intercondyloid fossa 

 (Fig. 60, h). 



(4) Ligaments of the Menisci. — There are five of 

 these, connecting the menisci with the femur or tibia. One 

 (Fig. 60, e) passes from the dorsal edge of the medial menis- 

 cus {c) transversely across the anterior crucial ligament {g) to 

 the proximal end of the tibia nearer the lateral side. A second 

 (Fig. 60, f) passes from the dorsal margin of the lateral 

 meniscus {d) transversely beneath the anterior crucial ligament 

 {g) to the proximal end of the tibia nearer the ventral side and 

 medial border. A third (Fig. 61,/) passes from the ventral 

 margin of the lateral meniscus obliquely across the anterior 

 crucial ligament {c) to the lateral side of the medial condyle of 

 the femur. The fourth (Fig. 61, c) is small, passing from the 

 medial angle of the ventral border of the lateral meniscus distad 

 to the popliteal notch. The fifth passes from the ventral border 

 of the medial meniscus laterad beneath the posterior crucial 

 ligament to the proximal end of the tibia, nearer the ventral 

 and lateral sides. 



Articulations between the Tibia and Fibula. — At the 

 proximal end the fibula is as it were suspended from the distal 

 side of the overhanging lateral tuberosity of the tibia by strong 

 ligamentous tissue. The capsule of the joint is formed by an 

 extension of the capsule of the knee-joint which passes between 

 the tibia and fibula on the ventral side. Forming the dorso- 

 lateral wall of this extension is a strong, thick ligament which 

 passes directly from the head of the fibula to the lateral surface 

 of the lateral tuberosity of the tibia. A second more delicate 

 ligament passes from the head of the fibula dorsoproximad to 

 the tubercle laterad of the crest of the tibia, bridging a groove 

 through which passes the tendon of M. extensor longus digi- 

 torum. 



The tibia and fibula are connected throughout their length 

 by an interosseus membrane. This is broad and very thin in 

 its proximal part, narrower and thicker distad.
