20 LIGAMEXTS AXD MUSCLES OF THE HORSE. 



HIP-JOINT. 



1. Capsular. — Attached above to the rim of the cotyloid cavity, 

 and to the cotyloid ligament ; below, around the head of 

 the femur. 



'2. Cotyloid. — Consists of a ring of tibro-cartilage attached 

 around the rim of the cotyloid cavity, which it deepens. 



3. Traisverse. —Is that part of the preceding which bridges over 



the cotyloid notch. 



4. I'lihiojemoral. —Attached in the sulcus on the head of the 



femur ; it passes inwards in the sub-pubic groove, blending 

 with the prepubic tendon and its fellow of the opposite side 

 (the fibres intercrossing). 



5. Round {llgamentiun teres \. — Attached below to the sulcus on 



the head of the femur, above, to the rough depression of 

 the cotyloid cavity (non-articular portion). 



Synovial Membrane. 



This completely lines the capsular ligament, and is also reflected 

 on the pubio-femoral and round ligaments. 



Movements. 



This joint admits of more extensive movements than any other 

 in the limbs. These are flexion, extension, abduction, ad- 

 duction, circumduction, and rotation. Abduction is re- 

 stricted by the pubio-femoral ligament, which is absent in 

 the other domesticated animals. 



STIFLEJOINT. 

 A. Femoro-tibial Ligaments. 

 1. Lateral. — 



{a) Internal. — Attached above to a tubercle on the internal 

 condyle of the femur, below, to the internal tuberosity of 

 the tibia. 

 lb) External. — Attached above to a depression on the external 

 condyle of the femur, below, to the head of the fibula.
