But the muscle may be divided into two bodies or bellies by a middle tendon ; it is then called a digastric muscle. 2. Muscular fasciculi, passing altogether from the same side to become anited into a tendinous cord, constitute a semi-^penniform muscle. 3. Muscular fasciculi may be implanted to right and left of the tendon, and form a pennated or penniform muscle. " This arrangement of fibres demonstrates that the leng

Muscular fasciculi may be implanted to right and left of the tendon, and form a pennated or penniform muscle. " This arrangement of fibres demonstrates that the length of the muscle, the length of its belly, and the length of its muscular fibres, should be care- fully distinguished. The first term is applicable to the whole of the muscle, the tendon included; the second, to the fleshy body of the muscle, with the exception of the tendon; the third, to the muscular fasciculi constituting this fleshy body: the latter idea is the most important, for it alone indicates the amount of contraction a muscle is sus- ceptible of, and consequently the possible ex- tent of movement it is capable of ;— Beaunis and Bouchard. 0. Vessels and Nerves.—The muscular tissue receives much blood; the fibrous tissue very little. The arteries are large, numerous, and each is acccompanied by two veins. The capillary vessels anastomose in such a manner as to form rectangular meshes, whose greatest diameter is directed towards the length of the muscle. The lymphatic vessels of the muscles are few; they sometimes penetrate their interior in following the capillaries; at other times they remain on the surface, in the external perimysium. The exist- Fig. 99. ence of lymphatics has not yet been demonstrated in tendons, aponeu- roses, or synovial membranes. The nerves emanate from the cerebro-spinal centre. At their terminal extremity they offer a small enlargement, called by Kouget the terminal motor plate, and by Doyere and Kiihne the ner- vous collin
