Before you name anything
Alright, take a deep breath and let's look at this together. Start by dropping to the lowest power and just observe the overall architecture. Notice the circular patterns? These are osteons, which are key to identifying compact bone. The mistake students often make is diving straight into high power and getting lost in the details. Instead, focus on recognising these circular structures first. Once you see them, you're halfway there. The central canals within these osteons are your next clue. Remember, you might not resolve individual lacunae or canaliculi clearly here, but that's okay. Just identifying the osteons and their arrangement is crucial. Keep calm and trust your process.
