Glossary of Terms Used in Human Anatomy and Physiology

Glossaries of terms are very helpful and important in many aspects. If you want to know or learn the correct definition, glossaries are essential.

Glossary ensures that everyone is discussing the same definition for the terms. Here we are providing the glossary of terms for human anatomy and physiology.

Whereas terminologies might differ all around the world and definitions change over time or some new terms might get added, hence we try our best to keep this dictionary of human anatomy and physiology up to date.
