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.
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.
The following outline is provided as an overview of and topical guide to human anatomy: . Human anatomy is the scientific study of the morphology of the adult human.It is subdivided into gross anatomy and microscopic anatomy.
Each type of cartilage has varying concentrations of components such as proteoglycans, collagen and water which determine its functional properties and location in the body. Fibrocartilage is most often found in the intervertebral discs, elastic cartilage is found in the external ear and hyaline cartilage is found on many joint surfaces in the ...
Connective tissue is found in between other tissues everywhere in the body, including the nervous system. The three meninges, membranes that envelop the brain and spinal cord, are composed of connective tissue. Most types of connective tissue consists of three main components: elastic and collagen fibers, ground substance, and cells. [2]
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]
Hyaline cartilage, makes up 50% of all cartilage protein. Vitreous humour of the eye. COL2A1: Collagenopathy, types II and XI: III: This is the collagen of granulation tissue and is produced quickly by young fibroblasts before the tougher type I collagen is synthesized. Reticular fiber. Also found in artery walls, skin, intestines and the ...
