The exterior of the horse . ament and the flexor tendons. It presents, also, along thelength of the pastern, two weak points, of which we will only make mention,and whose enlargement is always much less marked than that of the second and the smallest of the tendinous synovials is found in front,underneath the tendons of the extensors of the phalanges, and permits theirgliding upon the anterior face of the capsular ligament. It is extremely rarethat it communicates with the articular synovial membrane. It is susceptible ofbecoming distended over its whole periphery, unsustained by the tendons, andeven of rupturing its parietes into the surrounding connective tissue under theinfluence of internal pressure. Mechanism of the Articulation of the Fetlock.—By rea-son of the oblique direction of the first phalanx and of its superiorarticular surface, which play, with regard to the weight of the body,the role of an inclined plane, tlie principal bone of the canon constantly 292 THE EXTERIOR OF THE tends (Fig. 98) to press on the sesamoid hones, A, and tends to effecta dosing of the angle PBC The ligamentous apparatus, however, and the tendons which exist behind this angle, constantly re-sist this tendency and, by theirtenacity as well as their elas-ticity, transform the articularjoint into a veritable elasticspring admirably adapted to thesustentation of the body, thedispersion of the reactions, andthe impulsion of the mass. The suspensory ligament ofthe fetlock, being resisting andelastic, thanks to the few mus-cular fasciculi which enter intoits composition, yields more orless, according to the intensityof traction which it undergoes,to the lowering of the great sesa-moids, and through its attach-ments upon the bones of the canon distributes upon the latter a portionof the pressure of the weight of the body, in such a measure as iscompatible with their integrity. As to the cord T, of the flexor tendons, though much less elastic,it acts in the same
