SAMPLE 1
Hello everyone,
Hyaline cartilage, also known as white cartilage, is connective tissue that is smooth, clear, and slightly glossy. It can be found in parts of the body that need strength and elasticity. According to Vinod et al. (2021), it is present in areas such as the nasal cavity, trachea, larynx, and ends of long bones, where it forms the articular cartilage at joints. Also found in the fetal skeleton, bony tissue replaces hyaline cartilage during ossification. The structure of hyaline cartilage reflects its processes effectively. It comprises a tightly interwoven basket-like structure of collagen fibrils supported by a rigid, rubber-like ground substance of proteoglycans and water. This matrix imparts the tissue its characteristic blend of toughness and elasticity. Chondrocytes are found in the cavities known as the lacunae within the matrix. They are responsible for the production of collagen and proteoglycans necessary for the structural integrity of the matrix.
Lindahl et al. (2023) state that the fact that hyaline cartilage is non-frictional, translucent, smooth, and slippery is a plus for joints because bones shave against each other without discomfort. It is also involved with the distribution of loads across the arts and reduces the loads acting on a joint to prevent bone tissue damage and sustain joint integrity. In the respiratory system, hyaline cartilage gives rigidity to maintain patent airways in the nose and nasal passages, as well as trachea and bronchi for air passage during respiration. Hyaline cartilage also acts as a model for bone in the developing fetus, and with growth, it is progressively replaced by bony tissue.
The load-bearing property and smooth, low frictional surface of hyaline cartilage is also due to its organization at the micro level. The collagen fibers make it strong in tension; the ground substance or proteoglycan matrix draws water, allowing it to absorb pressure. This precise relationship between structure and function enables hyaline cartilage to provide support and flexibility and act as a smooth, low-friction bearing in joints.
