Thyroid Tubercle Superior

The thyroid is a protuberance in the neck formed in front by the thyroid-hyoid muscle and behind by the sternohyoid muscle. It is a process of the thyroid cartilage of the larynx and is also a prevertebral bone. Anteriorly, on the upper edge of the thyroid tubercle there is an interclavicular fossa. On the sides, the posterior edge passes upward and backward, forming the posterior and lateral parts of the lower jaw. The outer edge of the thyroid tubercle is slightly pronounced and allows you to determine the point where the cervical spine ends. At the lower edge of the tubercle, the anterior plate of the thyroid cartilage of the thyroid region adheres tightly to the transverse processes. Also on the upper edge of the thyroid tubercle there is a depression - a notch.

The superior tubercle of the thyroid cartilage is represented by two long protruding arches. Its posterior edge is narrowest at the neck, and widest at the apex. Somewhat forward from the posterior edge there is a slightly concave upper articular tubercle; the anterior edge of the thyroid cartilage includes a special protrusion of the anterior plate of the cricoid bone, the cornea of ​​the isthmus. The dorsal surface of the horny protrusion is in contact with the anterior edge of the thyroid cartilage, in contact with the outer surface of the cartilaginous process of the larynx, the upper end of the thyroid cartilage and part of the thyroid cartilage of the esophagus.
