As their name suggests, these folds do not produce sound. Vestibular folds: Also known as false vocal cords, these sit on top of the vocal folds and protect the larynx.Mucous membrane: This membrane lines the inner surface of the larynx.įinally, the hollow area inside the larynx contains two types of soft tissue folds:.Intrinsic ligaments and membranes: These ligaments and membranes form internal connections between the various structures of cartilage that form the larynx.Extrinsic ligaments and membranes: These ligaments and membranes attach the upper portion of the larynx to the hyoid bone and the lower part to the trachea.Ligaments and membranes in the larynx include: Cuneiform cartilages: These structures support the epiglottis and vocal folds.Corniculate cartilages: These structures are small cone-shaped cartilages that sit on the tips of the arytenoid cartilages.Arytenoid cartilages: A pair of flexible pyramid-shaped cartilages that cover the back part of the cricoid cartilage.It forms a closed circle at the bottom of the larynx. Cricoid cartilage: This structure is also known as the cricoid ring.Epiglottis: This structure attaches to the thyroid cartilage’s inner surface, covering the top opening of the larynx.The thyroid cartilage also forms the Adam’s apple. Thyroid cartilage: This structure wraps around the front and sides of the uppermost part of the larynx.It also consists of nine cartilage structures:

Sublarynx: This section makes up the bottom part of the larynx that connects to the trachea.Larynx: Refers to the middle portion of the larynx, which contains the vocal folds, or true vocal cords.Supralarynx: This section includes the top portion of the larynx and houses the vestibular folds, known as the false vocal cords.The larynx is a tube-shaped passageway that connects the throat (pharynx) to the windpipe (trachea).
