Question

Answer the following questions: 1. The osteogenic layer of the periosteum contains osteoblasts. Does the osteogenic layer of the periosteum allow for a bone to grow longer or to grow wider (thicker)? 2. Does the epiphyseal plate allow for a bone to grow longer or to grow wider (thicker)? 3. Which type of cartilage is articular cartilage? Hyaline corhllage 4. Which type of cartilage is found in the epiphyseal plate? Hyalive cartlag 5. The periosteum is made of which type of connective tissue (see your lecture notes from the histology unit for the most specific answer). 6. What is hemopoietic tissue and what is its function? 7.What is the difference between mineral deposition in bone and mineral reabsorptionin a bone?

Explanation / Answer

1. Perichondrium forms a cellular condensation along the periphery of the cartilagenous bones. This is followed by vascular invasion where the difeerentiation of chondrocytes into osteoblasts takes place. At that point a periosteum is said to exist. It begins producing a thin layer of bone known as bone bark. The bone bark encloses the nascent cartilagenous model and contributes to the width of the bone.
