    corresponding to the anterior surface of the transverse ligament; the ligament in fact which retains the process in its place. Close to the summit, but at the sides, are attached two ligaments whose course is obliquely transverse, and by means of which the odontoid process is strongly attached to the inner side of the condyles of the occipital bone. These ligaments are called the check ligaments, inasmuch as they check the rotatory motion of the head, limiting it to half a circle; nevertheless the rotatory motion of the head, as far as it goes, is, in the language of the natural philosopher, universal. The spinous process of this vertebra is very large and deeply grooved interiorly. The upper notches are placed much further back than the lower. The superior articular processes are nearly horizontal and somewhat convex; they are broader than the inferior, which are turned forwards and downwards. The transverse processes are short, and are neither bifurcated nor grooved. The foramen for the passage of the vertebral artery passing through their base, more resembles a short canal than a mere foramen; its direction is obliquely outwards. The laminae are thick and strong, and the foramen medullare is heart-shaped. Seventh Cervical Vertebra.—The last of the region, and physiologically the most remarkable. Its large and projecting spinous process, well known to artists; its irregularly formed transverse pro- cesses, carrying anteriorly a rudimentary rib, that is, the vestige of a rib, which though developed in other animals is not so in man; its close resemblance to the succeeding vertebra, the first dorsal, distinguish this vertebra from all the others. Its spinous process is not bifur- Fig. 12 * Fig. I3.f * Fig. 12.—Vertebra proeminens seen from above.—d, the lamina; e, hole for the vertebral artery, which, however, never passes through it; f points to the germ of the rudimentary rib ; c, articular process and notch ; h, body of the vertebra. -f- Fig. 13.—Same vertebra, seen from below.—a, spinous process; b, vertebral foramen; c, articular process; d, lamina; e, hole for the v. artery and vein ; /, germ or nucleus of the accessory rib; g, the supernumerary rib itself, sepa- rated from the anterior root of the transverse process by a distinct foramen ; h, body of the vertebra. + Fig. 14.—Same vertebra as seen in profile.—a, spinous process; c, e, superior articular process and notch, or incisura; h, body of the vertebra.
