Cricothyroid ligament
Description
The cricothyroid membrane is the fibrous tissue between the lower border of the thyroid cartilage and the upper border of the cricoids cartilage. This is where you can insert certain emergency airway devices.
Description
The cricothyroid ligament is a median placed elastic ligament that is
essentially the thickened median portion of the anterior cricothyroid
membrane. It begins as a broad band attached to the upper anterior
aspect of the cricoid cartilage and narrows as it ascends to attach to
the lower anterior aspect of the thyroid cartilage.
Function
Helps bind the cricoid and thyroid cartilages while limiting the
anterior-posterior rocking of the thyroid cartilage on the cricoid
cartilage.
