9° THE SKELETON OF THE CAT. 
ment (Fig. 60,2; Fig. 61, @), begins on the tibia at the edge 
of the popliteal notch (Fig. 61, 2), 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, 4). 
(4) LIGAMENTS OF THE MENISCI.—There are five of 
these, connecting the menisci with the femur.or tibia. One 
(Fig. 60, ¢) passes from the dorsal edge of the medial menis- 
cus (¢) transversely across the anterior crucial ligament (g) to 
the proximal end of the tibia nearer the lateral side. A second 
(Fig. 60, 7) passes from the dorsal margin of the lateral: 
meniscus (@) 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¢) 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.
