Where is fibrocartilage found and what is its function?
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 the function of cartilage fibrocartilage?
Fibrocartilage is a flexible, elastic, tough form of cartilage that provides cushioning in the joints.
Where is fibrocartilage most likely to be found?
Fibrocartilage is found in the pubic symphysis, the annulus fibrosus of intervertebral discs, menisci, and the temporal mandibular joint.
What is an example of fibrocartilage?
Fibrocartilage. Example : Intervertebral discs (between spinal vertebrae), Menisci (cartilage pads of the knee joint), the callus (formed at the ends of bones at the site of a fracture), between the Pubic Symphysis and at the junction where tendons insert into bone.
What does fibrocartilage look like?
It is a glossy blue-white in appearance and very resilient. 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.
How do you detect fibrocartilage?
Fibrocartilage is a transition tissue that should be viewed as a blend between hyaline cartilage and dense fibrous connective tissue. It is a white, densely arranged, opaque, tufted tissue with a mixture of both chondrocytes and fibroblasts.
What is the main function of cartilage?
Hyaline, or articular, cartilage covers the ends of bones to create a low-friction environment and cushion at the joint surface. When cartilage in the joint is healthy, it effectively allows fluid bending/straightening motions and protects the joint against weight-bearing stresses.
Which is the strongest cartilage?
Fibrocartilage
Fibrocartilage contains even more collagen fibers than hyaline cartilage. It’s the most rigid type of cartilage and can be found in intervertebral discs in the spine. It’s also the strongest type of cartilage.
What makes fibrocartilage so strong?
In fibrocartilage, the matrix is dominated by a dense regular network of bundles of collagen fibers arranged parallel to each other in several layers. The bundles in adjacent layers run in different directions which produces a strong material with moderate elasticity.
What are the 3 functions of cartilage?
The most important functions of cartilage include:
- Cartilage gives shape, support, and structure to other body tissues.
- It also helps to cushion joints.
- Cartilage also smoothens the bone surfaces at the joints.
- It is essential for the development and growth of long bones.
Is cartilage important for movement?
Cartilage: This smooth and flexible substance covers the tips of your bones where they meet. It enables bones to move without friction (rubbing against each other). When cartilage wears away, as in arthritis, it can be painful and cause movement problems.
Where is the fibrous cartilage located?
Fibrous cartilage may be found in such areas as between vertebral discs of the spinal cord. The outer ear, nose, and larynx are some locations of elastic. Hyaline cartilage, also referred to as articular cartilage, covers joint surfaces and additionally may be found in the shoulder and hips as well.
Where is fibrocartilage found?
Fibrocartilage is primarily composed of type I collagen, and is located in areas like the intervertebral discs and the pubic symphysis. Note that the chondrocytes are surrounded by a matrix which helps differentiate fibrocartilage from dense connective tissue.
What is the function of fibrocartilage?
The fibrocartilage occurs in the pubic symphysis, menisci of the stifle joint, and the annulus fibrosis of the intervertebral discs. The fibrocartilage is often associated with the dense connective tissue and its main function is to attach bones to other bones and provide restricted mobility in the joints.
