The nuchal ligament extends from the external occipital protuberance on the skull and median nuchal line to the spinous process of the seventh cervical vertebra in the lower part of the neck. [ 1 ] From the anterior border of the nuchal ligament, a fibrous lamina is given off.
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 ...
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 function of the cricoid cartilage is to provide attachments for the cricothyroid muscle, posterior cricoarytenoid muscle and lateral cricoarytenoid muscle muscles, cartilages, and ligaments involved in opening and closing the airway and in speech production. [citation needed]
The rounded upper projections of the back teeth are cusps. The hard white exterior covering of the tooth is the enamel. As the tooth tapers below the gumline, the neck is formed. Below the neck, holding the tooth into the bone, is the root of the tooth. The inner portions of the tooth consist of the dentin, a bonelike tissue, and the pulp.
one between the anterior surface of the ligament and the back of the odontoid process; The lateral atlantoaxial joint involves the lateral mass of atlas and axis. [4] Between the articular processes of the two bones there is on either side an arthrodial or gliding joint.
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]
