Questions: At the end of long bones, inside the spinal vertebrae, and inside the flat bones of the pelvis, is a spongy type of bone known as
- osteoclastic bone
- osteoblastic bone
- trabecular bone
- compact bone
Transcript text: At the end of long bones, inside the spinal vertebrae, and inside the flat bones of the pelvis, is a spongy type of bone known as
osteoclastic bone
osteoblastic bone
trabecular bone
compact bone
Solution
The answer is the third one: trabecular bone.
Explanation for each option:
Osteoclastic bone: This term is incorrect. Osteoclasts are cells that break down bone tissue, but there is no type of bone specifically called "osteoclastic bone."
Osteoblastic bone: This term is also incorrect. Osteoblasts are cells responsible for bone formation, but there is no type of bone specifically called "osteoblastic bone."
Trabecular bone: This is the correct answer. Trabecular bone, also known as spongy or cancellous bone, is found at the end of long bones, inside the spinal vertebrae, and inside the flat bones of the pelvis. It has a porous, lattice-like structure.
Compact bone: This is incorrect in this context. Compact bone, also known as cortical bone, is dense and forms the outer layer of bones, providing strength and structure, but it is not the spongy type of bone described in the question.
In summary, the spongy type of bone found at the end of long bones, inside the spinal vertebrae, and inside the flat bones of the pelvis is trabecular bone.
