Question

The structure of bone tissue suits the function. Which of the following bone tissues is adapted to support weight and withstand tension stress? A. spongy bone B. compact bone C. trabecular bone D. irregular bone

Answer 1

Compact bone is the type of bone tissue adapted to support weight and withstand tension stress because of its dense, solid structure.

Step-by-step explanation:

The structure of bone tissue is directly related to its function in the body. Among the options given, the bone tissue adapted to support weight and withstand tension stress is compact bone. Compact bone is the denser and stronger type of bone tissue, found under the periosteum and in the diaphysis of long bones where it serves to provide support and protection.

It is composed of osteons and forms the external layer of all bones, making it well-suited for bearing weight and enduring compressive forces due to its solid and dense structure. On the other hand, spongy bone, also known as cancellous bone, has a more open network of trabeculae with spaces in between, which makes it lighter and capable of supporting shifts in weight distribution, but less suited for directly withstanding heavy loads and tensions compared to compact bone.

Answer 2

B. Compact Bone

Step-by-step explanation:

Compact bone tissue is the strongest bone tissue type due to certain structural features. It has few spaces and serves to impart protection, support, and resistance against the stress produced by weight and movement. The compact bone tissue makes most of the diaphyses of long bones.

Osteon makes the structural unit of compact bone tissue and consists of concentric rings of lamellae present around the central osteonic canal. All the osteons of compact bone tissue are arranged in the same direction and run parallel to the length of the diaphysis of long bones which in turn impart these long bones the resistance against bending and fracture.

The thickness of the compact bone tissues and the lines of the stress in the bones vary from bone to bone giving them the additional strength.
