Questions: The structure of bone tissue suits the function. Which of the following bone tissues is adapted to support weight and withstand tension stress? compact bone trabecular bone irregular bone spongy bone Submit Request Answer

The answer is the first one: compact bone.

Explanation for each option:

1. Compact bone: This type of bone tissue is dense and forms the outer layer of bones. It is highly adapted to support weight and withstand tension stress due to its tightly packed structure, which provides strength and rigidity.

2. Trabecular bone: Also known as cancellous or spongy bone, this tissue is found inside bones and has a porous, lattice-like structure. While it helps to reduce the weight of bones and provides some support, it is not as well-suited to withstand high levels of tension stress as compact bone.

3. Irregular bone: This term refers to bones that do not fit into the other categories of bone shapes (long, short, flat, or sesamoid). Examples include vertebrae and certain facial bones. The term "irregular bone" describes the shape rather than the specific tissue type, so it is not directly related to the ability to support weight and withstand tension stress.

4. Spongy bone: This is another term for trabecular bone, which, as mentioned, has a porous structure and is not as well-suited for supporting weight and withstanding tension stress as compact bone.

Summary: Compact bone is the type of bone tissue that is best adapted to support weight and withstand tension stress due to its dense and strong structure.
