What does palpebra mean?
A palpebra is an eyelid: one of the folds of skin that covers the front of the eye and helps protect its surface. The term is especially common in anatomy, ophthalmology, and clinical descriptions of the eye. In such contexts, the upper palpebra and lower palpebra refer to the upper and lower eyelids respectively. Palpebra can also be used more broadly for the eyelid tissue or fold itself, rather than simply for the visible opening between the lids. Outside technical writing, eyelid is usually the natural everyday choice. The word is especially useful when precision matters, as in describing swelling, inflammation, movement, surgery, or the structure of the eye. Its Latin origin makes it recognizable in related medical terms such as palpebral, an adjective meaning “relating to the eyelids.”
nounAn eyelid, especially either of the movable folds of skin that protect and cover the front of the eye. The term is used chiefly in anatomy and ophthalmology.
- Either of the two eyelids or eyelid folds that cover and protect the front of the eye.
"The upper palpebra was lifted to examine the cornea."
"The lower palpebra moved slightly as she looked down."
"Inflammation of the palpebra can make the eye appear swollen."
Palpebrae is the standard Latinized plural used in anatomy and ophthalmology; palpebras is also encountered in modern usage.
"Both palpebrae were swollen after the procedure."
The technical word for an eyelid comes straight from Latin, where palpebra was already used for the delicate fold that shields the eye.
