. The comparative anatomy of the domesticated animals. Veterinary anatomy. ARTICULATIONS OF THE ANTERIOR LIMBS. Fie;. 1 into which it is inserted by becoming confounded with the intersesamoid liga- ments. Its posterior face, lined by the synovial membrane of the so-called sesa- moid sheath, is covered by the flexor tendons; it partly covers the middle ligament. The middle ligament, triangular and radiating, is composed of three particular fasciculi: two lateral (seen on each side of the superficial ligament in Fig. 131, A 8), and a median which has been generally confounded with the superficial ligament, although it is clearly distin- guished from it by its inferior insertion. Fixed in common to the posterior imprints of the first phalanx, these three fasciculi diverge in ascending to the base of the sesamoids, where they have their upper insertion. The deep ligament is constituted by two small bands concealed beneath the middle ligament. Thin, short, flattened before and behind, and intercrossed (Fig. 131, B 3), these bands are fixed to the base of the sesamoids in one direction, and in the other to the superior extremity of the first phalanx, near the margin of its articular surface. This ligament is covered on its anterior face by the synovial membrane of the articulation. CARPAL, METACARPAL, AND INTER-PHALANGEAL ARTICULATIONS OF THE HORSE (POSTERO- LATERAL view).
