Medical Conditions - Normal Anatomy Variant

Anatomical variation is the slight deviation of the human anatomical structures from the normal anatomy. Anatomic variants are found in a small population, and in most cases, they do not pose any risk or impact on physiology. They are also known as normal variants. Anatomies have been considered normal based on the strength of the population possessing them. Therefore, when most people have the same anatomy and are the fittest for survival, it is considered normal anatomy. So any slight deviation from the normal anatomy possessing no impact on the physiology is variant anatomy or normal variant.
