The ligament broadens [1] and thickens [2] medially. The anterior medial aspect of the ligament is lined by a thin layer of articular cartilage. [1] The neck of the odontoid process is constricted where it is embraced posteriorly by the transverse ligament [2] so it retains the dens in position even after all other ligaments have been sectioned ...
The tectorial membrane of atlanto-axial joint (occipitoaxial ligaments) is a tough membrane/ [1] broad, strong band [2] representing the superior-ward prolongation of the posterior longitudinal ligament (the two being continuous). [3] [1] [2] It attaches inferiorly onto (the posterior aspect of [2]) the body of axis. [3] It broadens superiorly.
The cruciate ligament of the atlas (cruciform ligament) is a cross-shaped (thus the name) ligament in the neck forming part of the atlanto-axial joint. It consists of the transverse ligament of atlas, a superior longitudinal band, and an inferior longitudinal band. The cruciate ligament of the atlas prevents abnormal movement of the atlanto ...
Transverse ligament: Should the transverse ligament of the atlas fail due to trauma or disease, the dens is no longer anchored and can travel up the cervical spine, causing paralysis. If it reaches the medulla death can result.
Just below the medial margin of each superior facet is a small tubercle, for the attachment of the transverse atlantal ligament which stretches across the ring of the atlas and divides the vertebral foramen into two unequal parts: the anterior or smaller receiving the odontoid process of the axis
The posterior atlantoaxial ligament is a broad, thin membrane attached, above, to the lower border of the posterior arch of the atlas; below, to the upper edges of the laminæ of the axis. It supplies the place of the ligamenta flava , and is in relation, behind, with the obliqui capitis inferiores .
The alar ligaments, along with the transverse ligament of the atlas, derive from the axial component of the first cervical sclerotome. [3] Function
Inferiorly, it becomes continuous with the anterior sacrococcygeal ligament. [3] Superiorly, between the skull and atlas, the ligament is continuous laterally with the anterior atlantooccipital membrane. [4] The ligament is thick and slightly more narrow over the vertebral bodies and thinner but slightly wider over the intervertebral discs. [5]
