Fig. 11 shows a side view, and Figs. 12 and 13 a posterior view of the phalangeal bones, with their articular ligaments. The lettering is the same in all three figures: _a_, lateral ligament of fetlock-joint; _b_, intersesamoid ligament; _c_, suspensory ligament of the fetlock; _d_, median branch of inferior sesamoid ligament; _d′_, lateral branches of inferior sesamoid ligament; _e_, deep inferior sesamoid ligament; _f_, lateral sesamoid ligaments; _g_, inferior coronary ligaments; _h_, superior coronary ligaments; _h′_, median coronary ligaments; _i_, lateral pedal ligament; _k_, lateral coronary ligament and suspensory ligament of the navicular bone; _l_, interosseous ligament.] 5. The _inferior sesamoid ligament_ (Figs. 11, _d′_, 12, _d_, _d′_, and 13, _d′_, _E_). This originates at the lowest part of the sesamoid bones and intersesamoid ligament, and consists of _three parts_ or branches. The _median branch_ (_d_) is the longest and strongest, and takes its lower attachment in the middle of the fibro-cartilaginous lip found on the upper border of the posterior face of the second phalanx. The _two lateral branches_ (_d′_) approach each other as they descend, and terminate on the sides of the roughened triangle on the posterior face of the first phalanx. 6. The _deep inferior sesamoid ligament_ (Fig. 13, _e_) is quite short, and consists of a number of distinct, thin fibrous bands lying directly against the bone and entirely covered by the median and lateral inferior sesamoid ligaments. These fibrous bands cross one another in passing from the sesamoids to the first phalanx. II. The =coronary joint= is the simplest of the three articulations of the foot. The long pastern furnishes two condyles and the short pastern two glenoid cavities. Besides a capsular ligament there are— 1. _Two lateral coronary ligaments_ (_k_) and, 2. _Six posterior coronary ligaments_,—namely, _two superior_ coronary ligaments (_h_), _two median_ coronary ligaments (_h′_), and _two inferior_ coronary ligaments (_g_). III. The =pedal articulation= (“coffin” joint) is an imperfect hinge-joint, and is formed by the condyles at the lower end of the short pastern and the two glenoid cavities in the united upper surfaces of the pedal and navicular bones. Besides the _capsular ligament_ (Figs. 12 and 13, _l_), which binds all three bones together, there are the following accessory ligaments: 1. _Two strong lateral ligaments_, an external and an internal (Fig. 11, _i_), whose posterior borders are lost in the lateral cartilages which cover them. 2. _Two lateral suspensory ligaments of the navicular bone_ (_k_). They begin on the posterior border and ends of the navicular bone, and terminate on the lower part of the anterior surface of the os suffraginis, where they are lost in the lateral ligaments of the coronary articulation.
