Tongue — circumvallate papilla (CVP)

🩺 Before you name anything

Alright, let's take a deep breath and start by looking at the overall shape at low power. You should see a large papilla, though the distinct circular trench may not be clearly visible in this image. This is your key feature for identifying a circumvallate papilla. Avoid jumping straight to high power; it’s easy to get lost in the details and miss the bigger picture. The mistake students often make is focusing too much on individual cells without recognising the papilla's characteristic architecture. Once you've identified the general area, know that taste buds are typically found on the lateral walls, but this requires higher magnification to confirm. Remember, the von Ebner glands open into the trench, but you might not resolve them clearly here. Focus on the papilla first, and you'll be on the right track.
