Root Explanation

Ultrastructural → It is formed from "ultra-" (meaning beyond) and "structural" (from Latin "structura", meaning structure). The word "ultrastructural" refers to details that are beyond the usual structural level, often used in the context of microscopic analysis.

Memory Tip

Think of 'beyond' ('ultra-') the usual 'structure' — that's why ultrastructural refers to details that go deeper than normal structure.
