Multiple Choice

When examining the gross anatomy of bone, what is a key difference between compact bone and spongy bone?

Compact bone is dense and forms the outer layer of bones, while spongy bone is porous and found inside bones.

Compact bone is responsible for producing blood cells, while spongy bone provides structural support.

Compact bone contains red bone marrow, while spongy bone contains yellow bone marrow.

Spongy bone is only found in the shafts of long bones, while compact bone is only found at the ends.

Verified step by step guidance

Understand the gross anatomy of bone: Bones are composed of two types of tissue—compact bone and spongy bone. Compact bone is dense and forms the outer layer of bones, while spongy bone is porous and found inside bones.

Clarify the functions of compact and spongy bone: Compact bone provides structural support and protection, while spongy bone is involved in metabolic functions such as housing bone marrow.

Differentiate the location of compact and spongy bone: Compact bone is typically found on the outer surface of bones, forming a protective layer, whereas spongy bone is located inside bones, particularly at the ends of long bones and in the interior of flat bones.

Examine the role of bone marrow: Compact bone does not contain red bone marrow; instead, spongy bone houses red bone marrow, which is responsible for producing blood cells. Yellow bone marrow, which stores fat, is typically found in the medullary cavity of long bones.

Address misconceptions: Spongy bone is not limited to the shafts of long bones, nor is compact bone restricted to the ends of bones. Both types of bone tissue are distributed based on their functional roles in the skeletal system.
