Epididymis

🩺 Before you name anything

Alright, take a deep breath. Let’s start by looking at the overall structure at low power. Notice how the field is filled with multiple circular profiles, indicating a highly coiled duct. This is characteristic of the epididymis. Now, focus on the lining of these ducts. You should see a pseudostratified columnar epithelium with long stereocilia. This is a key feature. The lumen often contains sperm, which is another clue. Students often rush to high power and get overwhelmed by details. Instead, start with the architecture, then the lining, and finally confirm with the presence of sperm. This systematic approach will help you confidently identify the specimen. Remember, the pseudostratified epithelium with stereocilia and sperm in the lumen are your signature features. You’ve got this!
