Understand the composition of hyaline cartilage: Hyaline cartilage is a type of connective tissue found in various parts of the body, providing support and flexibility. It is characterized by a glassy appearance and is composed of a matrix with collagen fibers and chondrocytes.
Identify the structures listed in the problem: The structures mentioned are intervertebral discs, costal cartilages, articular surfaces of joints, and the nasal septum.
Recall the typical locations of hyaline cartilage: Hyaline cartilage is commonly found in the nasal septum, costal cartilages, and articular surfaces of joints. These areas require the smooth, resilient properties of hyaline cartilage.
Consider the composition of intervertebral discs: Intervertebral discs are primarily composed of fibrocartilage, which is different from hyaline cartilage. Fibrocartilage is tougher and more fibrous, providing strength and support between vertebrae.
Conclude which structure is not composed of hyaline cartilage: Based on the understanding that intervertebral discs are made of fibrocartilage, identify them as the structure not composed of hyaline cartilage.
