KanjiJLPT N2
Examine (Medically)

checkup, seeing, diagnose, examine

Mnemonic

The doctor speaks words to the person on the exam table, asking about symptoms. Then she inspects their hairstyle, parting each strand to check the scalp for lesions. To examine (medically) is to leave nothing unchecked — not even a single hair on your head.
Additional thoughts
Picture a doctor methodically questioning a patient (words), looking at the person up close, and even combing through their hairstyle to check the scalp. The thoroughness ties all three radicals into the act of medical examination.
Quick recall
A doctor's words question the person, then she parts their hairstyle to fully examine (medically).
