1. What bone helps produce and repair the most blood cells?
2. What is an embryo’s skeletal system initially made from?
3. Define osteogenic, osteoblast, osteocyte, and osteoclast. (4 pts)
4. Define the following, intramembranous ossification and endochondral ossification. (2 pts)
5. What does “osseous” mean?.
6. What is the structure and look of a cancellous bone?
7. Compare and contrast calcification and ossification.
8. Describe what a compact bone looks like and where it is located on bones.
9. What is the structure of the bone matrix?
10. What is bone development after the age 18 considered?
1. The bone that helps produce and repair the most blood cells is the bone marrow, specifically the red bone marrow.
2. An embryo's skeletal system is initially made from cartilage.
3.
- Osteogenic: Cells that differentiate into osteoblasts.
- Osteoblast: Cells responsible for bone formation.
- Osteocyte: Mature bone cells that maintain bone tissue.
- Osteoclast: Cells responsible for breaking down and resorbing bone tissue.
4.
- Intramembranous ossification: Process of bone formation within a connective tissue membrane.
- Endochondral ossification: Process of bone formation from a hyaline cartilage model.
5. "Osseous" refers to something related to or resembling bone.
6. Cancellous bone has a spongy or porous structure with small cavities filled with bone marrow.
7. Calcification refers to the deposition of calcium salts in a tissue, while ossification refers to the process of bone formation.
8. Compact bone is dense and hard, with a solid appearance. It is located on the outer surface of bones and provides strength and protection.
9. The bone matrix is composed of collagen fibers and mineral salts, primarily calcium and phosphate.
10. Bone development after the age of 18 is considered to be restructuring and remodeling, rather than growth.
