What is the largest cartilage of the pharynx?
The thyroid cartilage The thyroid cartilage is the largest of the laryngeal cartilages. It is formed by a right and a left lamina that are separated posteriorly and joined together at an acute angle in the anterior midline, forming the laryngeal prominence, commonly known as the Adam's apple.
What are the 3 large cartilage pieces of the larynx?
The larynx is composed of three large unpaired cartilages (cricoid, thyroid, and epiglottis) and three paired smaller cartilages (arytenoid, corniculate, and cuneiform), making a total of nine individual cartilages.
What cartilage is in the larynx?
The larynx is a cartilaginous skeleton, some ligaments, and muscles that move and stabilize it and a mucous membrane. The laryngeal skeleton is nine cartilages: the thyroid cartilage, cricoid cartilage, epiglottis, arytenoid cartilages, corniculate cartilages, and cuneiform cartilages.

What is the cricothyroid cartilage?
The cricoid cartilage is a hyaline cartilage ring which fully encircles the trachea and composes the inferior-most boundary of the laryngeal skeleton. The term “cricoid,” (Greek, krikos meaning “ring-shaped”) refers to the signet-ring resemblance of the cricoid cartilage.

What is Corniculate cartilage?
The Corniculate Cartilages (cartilagines corniculatæ; cartilages of Santorini) are two small conical nodules consisting of yellow elastic cartilage, which articulate with the summits of the arytenoid cartilages and serve to prolong them backward and medialward.
