histology
組織学
解説 Definition
生物の組織の構造と機能を研究する学問。顕微鏡を使って細胞や組織を詳細に調べます。
Histology is the scientific study of the structure of tissues under a microscope. It is an important subject in biology and medicine because it helps scientists and doctors understand how body tissues are formed and how disease affects them. The word is mainly used in academic and medical contexts.
覚え方のコツ Memory Tip
histology は biology, geology, psychology と同じ -logy「学問」の形なので、まず「何かを研究する分野」だと押さえると記憶しやすい。核になる histo- は history や hospital と無関係で、ここでは「体の組織」を指すと割り切るのがコツ。出やすい場面は tissue sample, microscopic examination, cell and tissue structure など、顕微鏡で組織を観察する文脈。anatomy が体の形を大づかみに見るのに対し、histology はもっと細かい組織レベル、pathology は異常や病変を見る語、と並べて覚えると混同しにくい。
The ending `-logy` tells you it is a field of study, like `biology` or `geology`. The key is to remember that `histo-` here is about tissue, not about `history`. You can keep it clear by linking `histology` with `tissue samples`, microscopes, and the study of body tissues in fine detail.

histology の語源・成り立ち Etymology
histology はギリシャ語 histos「織物・組織」と -logy「学問」から。もともと「織られたもの」という感覚が体の組織へ広がり、顕微鏡で組織の成り立ちを調べる学問名になった。tissue, textile も同じ発想を感じさせる。
"Histology" comes from Greek histos, meaning "web," "tissue," or "something woven," and -logy, meaning "study of." The idea of woven material was extended to the body's tissues, seen as structured layers. That gave the word its modern sense of the study of body tissues.
