Corniculate Cartilage

Corniculate Cartilage The structure indicated is the corniculate cartilage of the larynx. The corniculate cartilages are also known as the cartilages of Santorini. The larynx consists of several cartilages, as well as lots of small muscles and a fibroelastic membrane. There are three pairs of small cartilages, and three large unpaired cartilages. The large unpaired cartilages include the cricoid cartilage, the thyroid cartilage and the epiglottis. The small paired cartilages include the arytenoid, the corniculate and the cuneiform cartilages. The corniculate cartilages are small cone shaped cartilages which sit on the apices of the arytenoid cartilages. Learn more about the …

Epiphyseal Line

Epiphyseal Line The structure indicated is the epiphyseal line. The epiphyseal plate is a plate of hyaline cartilage found in children and adolescents, located in the metaphysis at the ends of each long bone. Long bones consist of a diaphysis, metaphysis and epiphysis. The diaphysis is the main long section of the bone, the epiphysis is the rounded end of the long bone, and the metaphysis is the section of bone between the diaphysis and metaphysis.  In adults, the epiphyseal plate is replaced with the epiphyseal line and marks the point of union were the epiphysis meets the diaphysis. The …

Major alar cartilage

Major alar cartilage The structure indicated is the major alar cartilage (greater alar cartilage). The lateral walls of the external nose are comprised from three cartilages: Lateral process of septal cartilage Major alar cartilage Minor alar cartilage The major alar cartilage is located directly below the lateral process of the septal cartilage. It is structured such that it is bent in on itself to form both the medial and lateral walls of the nose. The crus laterale forms the lateral wall, whereas the crus mediale forms the medial wall.
