The term "underlid" is a noun that refers to the lower part of the eyelid that covers the eyeball when it is closed. It is the counterpart of the upper eyelid and plays a crucial role in protecting and maintaining the health of the eye.
The underlid, also known as the lower eyelid, is a thin, flexible layer of skin and muscle that forms a protective covering over the eye. It is responsible for keeping the eye moist and lubricated by producing tears and spreading them across the surface of the eye whenever necessary. The underlid also assists in removing foreign particles or debris from the eye through blinking.
Anatomically, the underlid consists of several essential components, including the tarsal plate, an elongated piece of cartilage that provides structure and support to the eyelid, as well as various glands that produce oils to keep the eye lubricated. Additionally, the underlid contains cilia, which are tiny hairs that help prevent particles from entering the eye.
Overall, the underlid serves as a vital part of the eye's protective mechanism, ensuring that it maintains proper lubrication and stays free from external irritants. Its coordinated functioning with the upper eyelid contributes to the overall health and wellbeing of the eye.
