The cricothyroid joint is the articulation between the inferior horn of
the thyroid cartilage and the
side of the cricoid cartilage.
It is a synovial joint, and has therefore a capsular ligament lined with
synovial membrane. The movements which take place are: (1) gliding in various
directions; and (2) rotatory movement around a transverse axis which passes
through the centers of the right and left joints.
