Question

8 fill in the blank 1 point answer stem cells mitotically produce answer cells which are immature bone cells and are responsible for bone formation. once they mature and become entrapped in matrix, they are called answer. the cells responsible for resorption (breaking down bone) are called answer. 9 multiple choice 1 point what 2 bone shapes are found in the hand and wrist? short & long sesamoid & irregular long & irregular flat & long 10 multiple choice 1 point what tissue is a semi - rigid form of connective tissue that provides flexibility to it’s structures? bone cartilage joints

Explanation:

1. For question 8: Osteogenic cells are the stem cells that produce bone cells. Osteoblasts are immature bone cells responsible for forming bone. When osteoblasts get trapped in the bone matrix, they mature into osteocytes. Osteoclasts are the cells that break down (resorb) bone tissue.
2. For question 9: The hand contains long bones (like metacarpals and phalanges) and the wrist contains short bones (carpals).
3. For question 10: Cartilage is a semi-rigid connective tissue that offers flexibility to structures; bone is rigid, joints are structures connecting bones, not a tissue type here.

Answer:

8.

• stem cells mitotically produce: Osteogenic
• cells which are immature bone cells and are responsible for bone formation: Osteoblast
• Once they mature and become entrapped in matrix, they are called: Osteocytes
• The cells responsible for resorption (breaking down bone) are called: Osteoclasts

1. A. Short & long
2. B. Cartilage
