Step 1: Identify the correct terms for the shaft and the expanded, knobby regions of a long bone.
The shaft of a long bone is called the diaphysis. This part of the bone is typically the longest and strongest section, containing primarily compact bone tissue. The expanded, knobby regions at each end of a long bone are called the epiphyses (epiphysis in singular form). These regions are composed of spongy bone tissue and contain red marrow, which is responsible for producing blood cells.
Step 2: Form a complete answer.
So, the correct answer is: Diaphysis/Epiphysis
Final Answer
So, the correct answer is: Diaphysis/Epiphysis
