Verified step by step guidance
1
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.
Identify the structures composed of hyaline cartilage: Hyaline cartilage is commonly found in respiratory cartilages (such as the trachea and bronchi), nasal cartilages (supporting the nose), and costal cartilages (connecting the ribs to the sternum).
Recognize the composition of intervertebral discs: Intervertebral discs are not composed of hyaline cartilage. Instead, they consist of fibrocartilage, which is tougher and contains more collagen fibers, providing strength and cushioning between vertebrae.
Compare hyaline cartilage with fibrocartilage: Hyaline cartilage is more flexible and less dense than fibrocartilage, which is designed to withstand pressure and provide support in areas like intervertebral discs.
Conclude which structure is not composed of hyaline cartilage: Based on the composition differences, intervertebral discs are not composed of hyaline cartilage, unlike the other options listed.
