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.
Hyaline cartilage has fewer cells than elastic cartilage; there is more intercellular space. Hyaline cartilage is found in the nose, ears, trachea, parts of the larynx, and smaller respiratory tubes. Fibrous cartilage has the fewest cells so it has the most intercellular space. Fibrous cartilage is found in the spine and the menisci.
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]
The auricle consists of a single piece of elastic cartilage with a complicated relief on its inner surface and a fairly smooth configuration on its posterior surface. A tubercle , known as Darwin's tubercle , is sometimes present, lying in the descending part of the helix and corresponding to the ear-tip of mammals.
Perichondrium can be found around the perimeter of elastic cartilage and hyaline cartilage. Perichondrium is a type of irregular collagenous ordinary connective tissue, and also functions in the growth and repair of cartilage. Perichondrium contains type I collagen [1] and type XII collagen. [2]
Elastin serves an important function in arteries as a medium for pressure wave propagation to help blood flow and is particularly abundant in large elastic blood vessels such as the aorta. Elastin is also very important in the lungs, elastic ligaments, elastic cartilage, the skin, and the bladder. It is present in jawed vertebrates. [17]
All three main types of cartilage found in vertebrates are represented among the different squid species: hyaline, elastic and fibrocartilage. Tubercles of hyaline cartilage are primarily associated with cranchiid or glass squid.
Micrograph of hyaline cartilage containing isogenous groups. An isogenous group (lat. "equal origin") is a cluster of up to eight chondrocytes [ 1 ] found in hyaline and elastic cartilage . [ 2 ]
