A number of these filaments may be said to form a fibre; a number of these fibres to form a fasciculus or bundle of fibres; and a number of fasciculi to form a muscle. Muscles assume a variety of form suited to their peculiar functions. Sometimes they are flat, extending over a consider- able space, and often they form a fleshy band, swelling out in the centre, and becoming small and tendinous at the points of their attachment to the bones. Fig. 173. Not only is a class of muscles employed in giving motion to the bones, but a numerous class is employed within the body in giving motion to the organs of nutrition, as the heart and the stomach. Anatomists enumerate in all about 400 muscles, a number wonderfully small when we consider their functions, and the infinite variety of motion in the animal; for, from the motions of the limbs to the expression of the face and modula- tions of the voice, all is moved by this machinery of surpassing beauty and simplicity. The bones, although harder than the muscular structure, are, like it, the parts of a living machine, furnished with their bloodvessels and nerves. They give to the animal its pecu- liar form, and, acted upon by the muscles, its power of pro- gression. The following figure represents the connexion of the prin- cipal bones of the horse :—
