Why is perichondrium absent in fibrocartilage?
In the articular cartilage and fibrous cartilage, due to their location, it has been seen that the perichondrium gets fused with surrounding connective tissue and cannot be distinguished.. hence it is deemed to be absent in these two..
Is perichondrium absent in hyaline cartilage?
Articular cartilage, which covers the articular surfaces of synovial joints, is a specialized hyaline cartilage that lacks a perichondrium (Fig. 5.4).
Which cartilage does not have perichondrium?
Hyaline cartilage is highly resistant to compression. It does NOT always have a perichondrium (as in articular cartilage). Its matrix consists of type II collagen and hyaluronan, and it is NOT found in the pinna of the ear and epiglottis (elastic cartilage is found there).
Is perichondrium present in hyaline cartilage?
Perichondrium is mainly found on the surfaces of elastic and hyaline cartilage, which can be found in multiple locations of the body, such as in the ears, nose, joints and ribs. Damage to the perichondrium is known as perichondritis, and can result from cartilage injuries.
Does tracheal cartilage have perichondrium?
Tracheal cartilage is covered with a dense fibrous membrane known as the perichoundrium. Between the superficial fibrous membrane and mature cartilage cells lies zone of immature cartilage made up of oval or spindle cells, and the inclusion of this zone in the perichondrium has long been a subject of controversy.
Is perichondrium present in all types of cartilage?
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 and type XII collagen.
What is perichondrium in elastic cartilage?
The perichondrium is a dense layer of fibrous connective tissue that covers cartilage in various parts of the body. Perichondrium tissue commonly covers these areas: elastic cartilage in parts of the ear.
Where are C shaped hyaline cartilage present?
Hyaline cartilage is the glass-like (hyaline) and translucent cartilage found on many joint surfaces. It is also most commonly found in the ribs, nose, larynx, and trachea….

Where is yellow elastic cartilage found?
the ear
Elastic cartilage, fibroelastic cartilage or yellow fibrocartilage 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.
Where hyaline cartilage is found?
Hyaline cartilage is found in the synovial joints and assists the motion of joints. It is composed of chondrocytes and extracellular matrix. Chondrocytes plays a major role in the organization of extracellular matrix, which is responsible for the biomechanical properties of cartilage tissue.
How is fibrocartilage and hyaline cartilage different?
Fibrocartilage and hyaline cartilage are two types of cartilage that occur in animals. Fibrocartilage contains a lot of collagen fibers in the matrix. But, hyaline cartilage contains fewer collagen fibers in the matrix. Both fibrocartilage and hyaline cartilage provide smooth and lubricated surfaces between bones.
Where is perichondrium found in cartilage?
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 and type XII collagen.
What is the difference between the perichondrium and the periosteum?
The perichondrium is a dense layer of fibrous connective tissue that covers many types of cartilage in the body, whereas the periosteum is a thin layer of membranous connective tissue that covers all bones in the body.
What happens if the perichondrium is damaged?
Damage to the perichondrium is known as perichondritis, and can result from cartilage injuries. This often occurs from microtraumas such as piercings, insect bites, or burns to the perichondrium tissue, leading to inflammation and, sometimes, infection.
What is the difference between chondrogenic layer and perichondrium layer?
The chondrogenic layer remains undifferentiated and can form chondroblasts. 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.
