Name the outer connective tissue layer around cartilage?
Cartilage is enclosed by a layer of dense connective tissue called the perichondrium, except on the articulating surfaces in joint cavities. The perichondrium has two layers-- a fibrous outer layer and an inner layer of cells with chondrogenic (cartilage-forming) potential. The chondrogenic cells undergo division and differentiate into chondroblasts.
What are the three kinds of skeletal cartilage?
Hyaline cartilage Elastic cartilage Fibrocartilage
Where in the body would you expect to find a perichondrium?
Peri means around and chondrium refers to cartilage. Therefore, perichondrium is a layer of dense irregular connective tissue that surrounds cartilage.
Is the ear made of fibrocartilage?
yes
What are articular discs composed of?
fibrocartilage
How does fibrocartilage gets its nutrition?
Hyaline Cartilage and Articular Cartilage get their nutrients through synovial or perichondrium fluid. Fibrocartilage does not have these so it gets nutrients through blood capillaries.
What is the perichondrium?
The perichondrium is a layer of dense irregular connective tissue which surrounds the cartilage of developing bone. It consists of two separate layers: an outer fibrous layer and inner chondrogenic layer. The fibrous layer contains fibroblasts, which produce collagenous fibers. The chondrogenic layer remains undifferentiated and can form chondroblasts or chondrocytes. Perichondrium can be found around the perimeter of elastic cartilage and hyaline cartilage, but not fibrocartilage. Perichondrium is a type of Irregular Collagenous Ordinary Connective Tissue, and also functions in the growth and repair of cartilage. Once vascularized, the perichondrium becomes the periosteum.
Is it true fibrocartilage is weaker than elastic and hyaline cartilage?
In specific areas yes. For example articular cartilage found in the knee and elbow is replaced by fibrocartilage when damaged as it lacks the ability to regenerate without the covering perichondrium
Do ears have perichondrium?
Yes the ears have a perichondrium.
What kind of connective tissue comprises the intervertebral discs between vertebrae?
Fibrocartilage (i.e Fibroelastic cartilage)
What membranes lack an epithelial layer?
Connective tissue membranes, which includes synovial membranes, meninges, fascia (superficial and deep fascia), fibrous pericardium, and perichondrium.
What is the covering around cartilage?
Perichondrium
What is the membrane that covers cartilage?
Perichondrium
