branches. The median, branch {d) is the longest and strongest, 

 and takes its lower attachment in the middle of the fibro-carti- 

 laginous 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 articula- 

 tions of the foot. The long pastern furnishes two condyles and 

 the short pastern two glenoid cavities. Besides a capsular liga- 

 ment tliere are — 



1. Two lateral coronary ligaments (Jc) and, 



2. Six posterior coronary ligaments, — namely, two superior 

 coronary ligaments (^), tivo median coronary ligaments (h'), 

 and two inferior coronary ligaments (g). 



III. The pedal articulation ("cofiin" joint) is an imper- 

 fect 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', ?), which binds all three 

 bones together, there are the following accessory ligaments : 



1. Two strong lateral ligaments, an external and an internal 

 (Fig. 11, ^), 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 suifraginis, where they are lost in the lateral 

 ligaments of the coronary articulation. 



3. The lateral ligaments of the lateral cartilages, navicular 

 bone, and os pedis. They are short, and unite the navicular 

 bone with the os pedis and lateral cartilages.
