Horse and man : their mutual dependence and duties . LIGAMENT OP THE NECK AND ITS BRANCHES. there is a strong ligament called scientifically liga-mentum nuchas.

The horse, however, needs a m ch more elaborateligament. At a is the upper and rounded portion whichis attached to the head. Widening and thickeningas it passes away from the head, it reaches the upperprocesses of several vertebras of the back. In additionit sends out a series of branches which are attachedto the vertebras of the neck, as shown at B. Still carrying on the train of reasoning, an elastichoof and neck would be useless if the remaining VERTEBRAE AND LIGAMENTS. portion of the spine were rigid, and so we find thatthe elasticity of the neck is carried through the restof the spine. In the illustration we have seen how VERTEBRAE AND LIGAMENTS. 213 the ligament of the neck is attached to the vertebra?of the back. The preceding illustration takes the fourvertebra? next in order. Fig. 1 shows how the verte-bra? are connected by ligaments, one set running aboveand the other below, as seen at A and c ; fig. 2 givesthe front view of the tenth vertebra, and shows at Bthe hole through which the spinal cord passes, andon the floor of which rests another ligament. Fi<*. 3is a diagrammatic representation of the vertebra?curved in action. There is yet another provision to ensure therequisite elasticity. At each end of the * body ofthe vertebra there is a thick, rounded, and veryelastic pad of cartilage, as may be seen diaoram-matically shown at fig. 2 of the illustration onpage 214. At a, the vertebra? are shown in theirnatural p
