Question

________ bone is always surrounded by ________. A) Compact; cartilage B) Compact; spongy bone C) Spongy; compact bone D) A diaphysis; an epiphysis E) Spongy; a medullary cavity

Answer 1

C) Spongy; compact bone

Step-by-step explanation:

Spongy bone is typically surrounded by compact bone in the structure of long bones. Compact bone forms the outer layer of bones (diaphysis), while spongy bone is found in the interior, particularly in the epiphyses and the metaphyses. The diaphysis (compact bone) surrounds the epiphysis (spongy bone). Hope this helps!
