Elastic cartilage, fibroelastic cartilage or yellow fibrocartilage [1] is a type of cartilage present in the pinnae (auricles) of the ear giving it shape, [2] provides shape for the lateral region of the external auditory meatus, [3] medial part of the auditory canal [3] Eustachian tube, corniculate and cuneiform laryneal cartilages, [3] and the epiglottis.
Thick elastic fibers from the visceral pleura (outer lining) of the human lung. Elastic fibers are found in the skin, lungs, arteries, veins, connective tissue proper, elastic cartilage, periodontal ligament, fetal tissue and other tissues which must undergo mechanical stretching. [1] In the lung there are thick and thin elastic fibers. [3]
There are three different types of cartilage: elastic (A), hyaline (B), and fibrous (C). In elastic cartilage, the cells are closer together creating less intercellular space. Elastic cartilage is found in the external ear flaps and in parts of the larynx. Hyaline cartilage has fewer cells than elastic cartilage; there is more intercellular space.

The visible part is called the auricle, also known as the pinna, especially in other animals.It is composed of a thin plate of yellow elastic cartilage, covered with integument, and connected to the surrounding parts by ligaments and muscles; and to the commencement of the ear canal by fibrous tissue.
In the human larynx, the cuneiform cartilages (from Latin: cuneus 'wedge' + forma 'form'; also known as cartilages of Wrisberg) are two small, elongated pieces of yellow elastic cartilage, placed one on either side, in the aryepiglottic fold. [1] The cuneiforms are paired cartilages that sit on top of and move with the arytenoids. [2]
In cases like this, the body will form a scar in the area using a special type of cartilage called fibrocartilage. [2] Fibrocartilage is a tough, dense, and fibrous material that helps fill in the torn part of the cartilage; however, it is not an ideal replacement for the smooth, glassy articular cartilage that normally covers the surface of ...
Isogenous groups differentiate into individual chondrocytes where they continue to produce and deposit extracellular matrix (ECM), lengthening the cartilage and increasing its diameter. [3] [5] This is termed interstitial growth and is one of only two ways cartilage can grow. [4] Cartoon representation of hyaline cartilage with isogenous groups.
