Question

anatomy and physiology
what is letter c referring to?
○ medullary cavity
○ metaphysis
○ diaphysis
○ epiphysis

Explanation:

To determine what letter C refers to in the bone diagram (Anatomy and Physiology context), we analyze the options:

• Medullary Cavity: Central cavity of long bone, but not matching C's typical label here.
• Metaphysis: Region between epiphysis and diaphysis, not C's usual label.
• Diaphysis: The shaft of a long bone, often labeled in such diagrams (matches typical bone structure labeling for the shaft).
• Epiphysis: The end part of a long bone, not the shaft.

So the correct option is Diaphysis.

Answer:

C. Diaphysis
