Question

What are the major differences between spongy bone and compact bone?

a) Spongy bone is denser and stronger than compact bone
b) Spongy bone is found in the diaphysis of long bones; compact bone in the epiphysis
c) Compact bone contains trabeculae; spongy bone has a solid structure
d) Compact bone is porous; spongy bone is dense and lacks pores

Answer 1

The major differences between compact bone and spongy bone are that compact bone is denser and stronger, found in the shaft of long bones, while spongy bone is lighter and has a porous structure, found in the ends of long bones.

Step-by-step explanation:

Compact bone is the denser, stronger type of bone tissue and can be found under the periosteum and in the diaphyses of long bones. It provides support and protection.

Spongy bone, on the other hand, is found in the end (or epiphysis) of a long bone. It is lighter and less dense than compact bone, with tiny plates called trabeculae that give it strength.

In summary, compact bone is dense and strong, found in the shaft of long bones, while spongy bone is lighter and has a porous structure, found in the ends of long bones.
