How does the matrix differ in each of the three types of cartilage?
To review:
The differences of matrix in the three types of cartilage.
Introduction:
Cartilages are the smooth elastic tissues, which protect and surround the ends of the long bones at joints. Cartilages are structural components of ear, nose, intervertebral discs, bronchial tubes, and rib cages. These structures are present throughout the adult human body having the tendency of resiliency and 60-80% water.
Explanation of Solution
Cartilages are of three types, namely elastic cartilage, fibrocartilage, and hyaline cartilage. These are the connective tissues, which consist of chondrocytes and have sufficient extracellular matrix. In the cartilage tissue, every chondrocyte is present in the space of the matrix. Each cartilage differs from each other with respect of matrix. These differences are as follows:
1. In hyaline cartilage, the fiber that is present in the matrix is collagen, which makes very thin networks of collagen fibrils.
2. The elastic cartilage resembles hyaline cartilage, but the matrix of elastic cartilage consists of numerous elastic fibers having delicate collagen fibrils.
3. The matrix of fibrocartilage contains thick collagen fibers that are capable of resisting extreme tension and compression.
