Dense tissues such as uterus, prostate and thyroid should be oriented how?

Dense glandular tissues like uterus, prostate, and thyroid are best prepared so the cutting plane can pass through them along a broad, angled surface. Placing the tissue flat and diagonal in the embedding block sets up a cutting plane that runs through the tissue with less resistance, making microtomy smoother and reducing distortions. This orientation helps reveal multiple glands and their lumens in representative sections, showing the characteristic architecture of these organs. Standing the specimen on end to force a lumen into view tends to yield sections where glands are not well represented or are obscured by oblique cuts, while flat on edge provides too limited a view of the tissue’s architecture.
