Superior articulai pt ocesi Facet for tubercle of. 19.—A th Transverse Processes.—The transverse processes arise from the same parts of the arch as the posterior roots of the transverse processes in the neck, and are situated behind the articular processes and pedicles; they are thick, strong, and of great length, directed obliquely backward and outward, presenting a clubbed extremity, and having on its anterior part near its tip a small concave surface, for articulation with the tubercle of a rib (fovea costalis transversalis). Besides the articular facet for the rib, three indistinct tubercles may be seen arising from the transverse processes—one at the upper border, one at the lower border, and one externally. In man they are of comparatively small size, and serve only for the attachment of muscles. But in some animals they attain con- siderable magnitude, either for the purpose of more closely connecting the segments of this portion of the vertebral column or for muscular and ligamentous attachment. The peculiar thoracic vertebrse are the first, ninth, tenth, eleventh, and twelfth (Fig. 20). First Thoracic Vertebra.—The first thoracic vertebra presents, on each side of the body, a sin^e^ntire articular facet for the head of the first rib and a demi- facet for the upper half of the second. The body is like that of a cervical vertebra, being broad transversely, its upper surface is concave, and lipped, pneach side. The articular surfaces are oblique,"and the spinous process thi
