	Atlas (anatomy) - Wikipedia, the free encyclopedia
		The anterior arch forms about one-fifth of the ring: its anterior surface is convex, and presents at its center the anterior tubercle for the attachment of the Longus colli muscles; posteriorly it is concave, and marked by a smooth, oval or circular facet (fovea dentis), for articulation with the odontoid process (dens) of the axis.
		The upper and lower borders respectively give attachment to the anterior atlantooccipital membrane and the anterior atlantoaxial ligament; the former connects it with the occipital bone above, and the latter with the axis below.
		The posterior arch forms about two-fifths of the circumference of the ring: it ends behind in the posterior tubercle, which is the rudiment of a spinous process and gives origin to the Recti capitis posteriores minores.

		The anterior portion is the homologue of the rib in the thoracic region, and is therefore named the costal process or costal element: it arises from the side of the body, is directed lateralward in front of the foramen, and ends in a tubercle, the anterior tubercle.
		The posterior part, the true transverse process, springs from the vertebral arch behind the foramen, and is directed forward and lateralward; it ends in a flattened vertical tubercle, the posterior tubercle.
		The transverse processes are of considerable size, their posterior roots are large and prominent, while the anterior are small and faintly marked; the upper surface of each has usually a shallow sulcus for the eighth spinal nerve, and its extremity seldom presents more than a trace of bifurcation.

		The present invention is devised to produce directed atlantooccipital support in a manner which satisfies the needs of various treatment and stress relief modalities.
		The cervical tee appliance 10 comprises a flattened base member 12 and a cervical support member 14 which are joined to form a rigid structure having the cervical support member 14 deviating from a normal to a surface of the base member 12 by a small angle.
		The purpose of contour 50 is to simulate the curvature of the hands of a therapist in performing supportive massage of the atlantooccipital joint region and therefore the curvature may deviate somewhat from that aforedescribed in order to more closely match the character of practical therapeutic manipulation.

		The presence of clinically significant anterior compression of the cervicomedullary junction by a retroflexed or invaginated odontoid was regarded as a contraindication for primary decompression of the posterior fossa.
		Posterior fossa decompressions were performed under somatosensory evoked potential monitoring with the patient in the prone position and the head flexed in a Mayfield headholder.
		The introduction of CDU as an intraoperative guide for posterior fossa surgery is an important technological advance that permits the neurosurgeon to tailor operative steps ac-cording to patient-specific variables on the basis of real time anatomical and physiological measurements.
