Summary
The cartilaginous and bony structures of the larynx include the hyoid bone as well as the thyroid and cricoid cartilages. The trachea begins below the cricoid cartilage.
The hyoid bone, thyroid cartilage, and tracheal cartilages are incomplete rings, with posterior membranous walls. In contrast, the cricoid cartilage is a complete ring, forming an important structural attachment for muscles and ligaments of the larynx. The cricoid cartilage ensures airway patency by stenting the larynx open.
The cricothyroid membrane is situated between the thyroid and cricoid cartilages in the midline anteriorly. It is located directly beneath the skin, providing direct and easy access to the airway. This membrane is bordered superiorly by the thyroid cartilage, inferiorly by the cricoid cartilage, and laterally by the paired cricothyroid muscles. In adults, it is approximately 1 cm tall and 2–3 cm wide.
The vocal cords are enclosed within the thyroid cartilage, approximately 1 cm from the upper border of the cricothyroid membrane.
The cricothyroid membrane is about four fingerbreadths from the suprasternal notch.
