What is a fibrocartilage?
Fibrocartilage is the tough, very strong tissue found predominantly in the intervertebral disks and at the insertions of ligaments and tendons; it is similar to other fibrous tissues but contains cartilage ground substance and chondrocytes.
What is the function of fibrocartilage connective tissue?
Fibrocartilage provides the tough material of the intervertebral discs; the intraarticular cartilages of the knee, wrist and temporo-mandibular joints; the articular cartilage of the temporo-mandibular joint and of the joint between the clavicle and the sternum.
What is yellow elastic cartilage?
Elastic cartilage or yellow cartilage is a type of cartilage present in the pinnae (auricles) of the ear giving it shape, provides shape for the lateral region of the external auditory meatus, medial part of the auditory canal Eustachian tube, corniculate and cuneiform laryneal cartilages, and the epiglottis.
Is hyaline cartilage an epiglottis?
There are three types of cartilage: Hyaline – most common, found in the ribs, nose, larynx, trachea. Elastic – is found in the external ear, epiglottis and larynx.
What type of collagen is fibrocartilage?
Type I collagen
Fibrocartilage contains large bundles of collagen fibres made up of Type I collagen. These bundles run linearly through the tissue separated by a cartilage matrix containing chondrocytes.
What is the difference between hyaline elastic and fibrocartilage?
Hyaline cartilage contains fibers made primarily of type II collagen only. Fibrocartilage contains type II collagen but also contains abundant type I collagen. Elastic cartilage contains type II collagen and elastic fibers.
What is a major characteristic of fibrocartilage?
A major characteristic of fibrocartilage is its unique amount of flexibility and elasticity. The basic difference between dense irregular and dense regular connective tissue is in the amount of elastic fibers and adipose cells present.
What is the difference between elastic tissue and elastic cartilage?
The elastic cartilage refers to a cartilage that is more opaque, flexible, and elastic than hyaline cartilage, and is further distinguished by its yellow color while the elastic connective tissue refers to a connective tissue composed of elastic fibers produced by fibroblasts that can stretch up to 1.5 times their …
What is the difference between elastic cartilage and hyaline cartilage?
Hyaline cartilage is a translucent white type of cartilage present in areas of the body such as the joints. The main difference between this type of cartilage and elastic cartilage is that elastic cartilage contains many elastic fibers, whilst hyaline cartilage contains a matrix of mainly collagen fibers.
What type of cartilage is epiglottis?
elastic cartilage
Larynx. The epiglottis is elastic cartilage and has fenestrations , which usually contain seromucous glands, and may serve as a conduit for carcinomas to enter the preepiglottic space. The arytenoid cartilages are small hyaline cartilages associated with mucoserous glands and are important in phonation.
