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 are the 4 purposes of fibrocartilage?
Fibrocartilage occurring within the body can be divided into four categories with specific functions: intra-articular fibrocartilage (e.g., menisci), acting as buffers and spacers in joints with frequent movement and high impact; connecting fibrocartilage (e.g., intervertebral disks) in limited-motion joints; …
What is the structure of 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.
How do you distinguish fibrocartilage?
The main difference between fibrocartilage and hyaline cartilage is that fibrocartilage is stiff and contains many collagen fibers whereas hyaline cartilage is a soft cartilage that contains fewer fibers.
How fibrocartilage gets its nourishment without perichondrium?
Synovial Fluid – this is found in joints and supplies nutrients to surrounding chondrocytes (cartilage cells) through diffusion. This is how articular cartilage (the cartilage in bones) receive nutrients, as they don’t have a perichondrium.
Where is hyaline found?
Hyaline cartilage is the most widespread and is the type that makes up the embryonic skeleton. It persists in human adults at the ends of bones in free-moving joints as articular cartilage, at the ends of the ribs, and in the nose, larynx, trachea, and bronchi.
What cells are found in fibrocartilage?
Fibrocartilage is a specialized form of connective tissue in which the ground substance is cartilage. The fibrous and cartilaginous components render this tissue extremely tough and resilient. The cell types found in this connective tissue include both fibroblasts/cytes and chondroblasts/cytes.
What is a major characteristic of fibrocartilage?
True. A major characteristic of fibrocartilage is its unique amount of flexibility and elasticity. False. Functions of connective tissues include binding, support, insulation, and protection.
What cell type is in fibrocartilage?
fibroblasts

Why is 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.
Why do bones need hyaline?
Where bone ends meet to form a joint, they are covered by hyaline cartilage. This cartilage appears bluish white and glistening in a normal healthy joint. Its primary function is to provide some cushioning and minimize friction between the bone ends.
