. The anatomy of the domestic animals. Veterinary anatomy. MVSCLES OF THE ABDOMEN 377 costal cartilage, to the tenth and eleventh cartilages a little (ca. 1 to 2 cm.) below the junction with the rib, to the twelfth rib at its ventral end and to the last rib below its middle. The cupola is very unsymmetrical; on the left side it is opposite the sixth rib, while on the right it is an intercostal space further back. Muscles of the Back and Loins The serratus dorsalis anterior arises from the median raphe of the neck and the first sLx or seven thoracic spines, and is inserted into the second to the ninth ribs. It is well developed. The serratus dorsalis posterior—much weaker—arises from the lumbo-dorsal fascia, and is inserted into the last three or four ribs. Thus one or two ribs intervene between the two. The longissimus costarum is well developed, and extends from the iliimi to the sixth, fifth, or fourth cervical vertebra. The longissimus dorsi resembles that of the other animals, but the spinalis et semispinalis separates clearly from the longissimus proper at the sixth or seventh thoracic vertebra. It is inserted into the articular and spinous processes of the last six cervical vertebrae. It has no depression in the ~v,_^ s^ lumbar region for the glu- ^^^..^ 6 h teus medius. The intertransversales are fleshy, as in the ox. The interspinales are distinct and are most devel- oped in the Imnbar Muscles of the Tail These present the same general arrangement as in the horse. The sacro- coccygei, however, arise on the lumbar vertebrae also, and the coccygeus on the ischiatic spine. There is a sacro-coccygeus accessor- ius, which arises on the medial border of the ilium, the edge of the sacrum, and the transverse processes of the first coccygeal vertebrae, and is inserted between the dorsal and lateral sacro- coccygei. It is homologous with the intertransversales. Fig. 325.—Muscles of Tui, Axus, and Genhtal Organs of Dog. /. Ilium: ^. femur; 3, tuber ischi
