CHAPTER XVII DISEASES OF THE FOOT General Discussion.—The foot of tlio horse as generally spoken of, includes the hoof and the structures that are enclosed by it (Fig. 3G). It may be divided into three parts, the insensi- tive and sensitive structures and the bony core. The insensitive foot or hoof is divided into wall, sole, frog and bars. The sensitive foot is divided into vascular tissue and elastic apparatus. The vascu- lar tissue is in turn divided into coronary cushion, lamina? and vel- vety tissue. The elastic apparatus is divided into plantar cushion and fibro-cartilages. The bony core is formed by the navicular and third digital bones. The hoof and vascu- lar tissue in tura enclose the elastic apparatus and bony core. The wall forms that portion of the hoof seen when the foot rests on the ground (Fig. 37). It is covered by a thin layer of hoiiiy tissue, the iieripole, that coats over the wall and assists in preventing its drying out. On lifting the foot and examining its inferior surface, it is noticed that the wall at the heels is inflected under the foot and in a forward direction. This portion of the wall is termed the hars. Within the bearing margin of the wall and in front of the bars is a thick, concave, horny plate that forms the sole. At the heels and betv/een the 160.
