Verified step by step guidance

Understand the role of cartilage in the development of long bones during embryonic growth. Cartilage serves as a template for bone formation in a process called endochondral ossification.

Review the types of cartilage: Hyaline cartilage, fibrocartilage, and elastic cartilage. Hyaline cartilage is the most abundant type and provides smooth surfaces for joint movement and structural support.

Learn the characteristics of hyaline cartilage. It is composed of a matrix rich in collagen fibers and proteoglycans, making it ideal for forming the initial framework of long bones.

Understand why fibrocartilage and elastic cartilage are not suitable for this role. Fibrocartilage is specialized for resisting compression and tension, while elastic cartilage provides flexibility, neither of which are primary functions in bone development.

Conclude that hyaline cartilage is the correct tissue type that serves as the forerunner of long bones in the embryo, as it forms the cartilage model that is later replaced by bone during endochondral ossification.
