Inferior articular process bral artery Transverse process B Fig. 109.—Epistropheus ( Axis), (A) from behind and above, (B) from the left side. The anterior surface of the body has a raised triangular surface, which ends superiorly in a ridge passing upwards to the neck of the dens. The roots of the vertebral arches are concealed above by the superior articular processes; inferiorly, they are deeply grooved. The laminae—prismatic on section—are thick and strong, ending in a stout, broad, and bifid spinous process, the under surface of which is deeply grooved, whilst its sides meet superiorly in a ridge. Placed over the roots of the vertebral arches and the anterior root of the transverse processes are the superior articular surfaces. These are more or less circular in shape, slightly convex from before backwards, flat from side to side, and are directed upwards and a little laterally. They are channelled inferiorly by the foramina trans- versaria, which turn laterally beneath them. The grooves by which the second cervical nerves leave the vertebral canal cross the laminae immediately behind the superior articular processes. The inferior articular processes agree in form and position with those of the remaining members of the series, and are placed behind the inferior intervertebral notches. The transverse process is markedly down-turned, with a single pointed extremity. The sixth cervical vertebra often displays an enlargement of the anterior tubercle on the transverse process, called the carotid tubercle from the circumstance that the carotid artery may be conveniently compressed against it. It is necessary to add, however, that the tubercle is not always well Please note that these images are extracted f
