Which of the following is false about trabecular bone?

• A. Trabecular bone contains red bone marrow.
• B. Trabecular bone is primarily found in the diaphysis of long bones.
• C. Trabecular bone has a porous structure.
• D. Trabecular bone is also known as spongy bone.

Answer: (B)

Verified step by step guidance

1. Understand the structure and location of trabecular bone: Trabecular bone, also known as spongy bone, is characterized by its porous, lattice-like structure. It is typically found at the ends of long bones, within the epiphysis, and in the interior of other bones such as the vertebrae and pelvis.
2. Identify the function of trabecular bone: Trabecular bone is crucial for supporting the production of blood cells, as it contains red bone marrow. This marrow is responsible for hematopoiesis, the process of forming new blood cells.
3. Differentiate between trabecular and cortical bone: Trabecular bone is distinct from cortical bone, which is dense and forms the outer layer of bones. Cortical bone is primarily found in the diaphysis, or shaft, of long bones, providing structural support and protection.
4. Evaluate the statements given in the problem: The statement 'Trabecular bone is primarily found in the diaphysis of long bones' is false because trabecular bone is mainly located in the epiphysis, not the diaphysis.
5. Conclude the analysis: Based on the understanding of trabecular bone's structure, location, and function, the false statement is identified as the one regarding its primary location in the diaphysis of long bones.
