 Pan, Patella, from behind. 



The patella has a b a s e, an apex, an anterior rough, and a 

 posterior surface, which latter is divided into two articular facets, 

 and moves along the groove between the two condyles of the femur. 



177. The Semilunar Fibro-Cartilages, Fibrocartilagines 



interarticulares, seen from above. 



The convex thickened border of each semilunar cartilage is turned 

 toward the capsule , the concave thinned border toward the Eminentia 

 intercondyloidea of the tuberosities of the tibia. The internal semilunar 

 fibr o - car til age is less curved, and at its convex border thicker 

 than the external (Fig. 178); the anterior extremities of these carti- 

 lages are connected by means of a transverse ligament ; these extremities 

 are inserted in front, the posterior behind the Eminentia intercondyloidea.
