48 EQUINE ANATOMY. 



Posterior, from posterior face of femur to tibia. In relation to 

 external gastrocnemius and popliteal artery. 

 Crucial. 



(a) Anterior or external from front of tibial spine to inner side 

 of external condyle. 



(b) Posterior or internal, in opposite direction. 



Inter articular fibro-cartilages (or menisci), (a) right and (b) 

 le/t attached to tibial spine, and by fasciculi to femur and tibia. 

 Synovial membrane. 



(a) Middle portion under patella. 



(b) Lateral portions under lateral ligaments. 

 Action. 



Flexion, extension and rotation on menisci. 



TIBIO-FIBULAR ARTICULATION. 



A planijorm diarthrosis, between tibia and fibula. 

 Ligaments. 



Two lateral fasciculi, from sides of fibula to tibia. 



Interosseous, between two bones, leaving a space called tibio- 

 fibular arch. 

 Action. 



Limited. 



HOCK OR TARSAL ARTICULATION. 



Tibio-tarsal. 



A ginglymus, between lower end of tibia and astragalus. 

 Ligaments. 



Anterior. From front of tibia to astragalus, scaphoid, great 

 cuneiform bones and astragalo-metatarsal ligament. 



Internal lateral. 



(a) Superficial fasciculus, from inner extremity of tibia to sides 

 of tarsus and metatarsus. 



(b) Middle fasciculus. 



Tibial tuberosity to astragalus and calx. 



(c) Deep fasciculus. 

 From tibia to astragalus. 

 External lateral.
