D
Fibrocartilage
Verified step by step guidance
1
Understand the role of tissues in the development of long bones during embryonic growth. Long bones form through a process called endochondral ossification, where a cartilage model is replaced by bone tissue.
Identify the type of cartilage that acts as the precursor to bone tissue in this process. Hyaline cartilage is the specific type of cartilage that serves as the forerunner of long bones in the embryo.
Review the characteristics of hyaline cartilage. It is smooth, glassy, and provides a template for bone formation. It is found in areas like the embryonic skeleton, articular surfaces of joints, and the respiratory tract.
Compare hyaline cartilage with the other options provided: Elastic cartilage (flexible, found in the ear and epiglottis), Dense regular connective tissue (provides tensile strength, found in tendons and ligaments), and Fibrocartilage (strong and resilient, found in intervertebral discs and menisci). None of these serve as the precursor for long bones.
Conclude that hyaline cartilage is the correct answer based on its role in endochondral ossification and its presence in the embryonic skeleton.
