What is Atrichous? Definition, Examples, and More

Atrichous is a term used in biology to describe an organ or structure that lacks hairs or scales. It is derived from the Greek words "atrichos," meaning "hairless," and "ous," meaning "pertaining to."

In humans, for example, the skin is atrichous because it does not have any hair. Similarly, the eyeballs are atrichous because they do not have any eyelashes or eyebrows. Other examples of atrichous structures in the human body include the palms of the hands and the soles of the feet.

Atrichous can also be used to describe plants that lack hairs or scales on their leaves, stems, or other parts. For example, a leaf that is smooth and hairless might be described as atrichous.

Overall, the term atrichous is used to describe any structure or organ that lacks hairs or scales, whether it is in animals or plants.
