Canthal is a word that refers to the area around the eye where the upper and lower eyelids meet. The correct spelling is /ˈkænθəl/, which is pronounced as "can-thuh l." The word originates from the Greek word "kanthos," which means "corner of the eye." The spelling reflects the Greek origin of the word, with the combination of "c" and "th" representing the Greek letter kappa, and the addition of the vowel sound "a" in between. Correct spelling is important in understanding and using specialized medical terminology.
Canthal is an adjective that refers to an anatomical feature related to the corners of the eyes. Specifically, it describes the area where the upper and lower eyelids meet at the inner and outer corners of the eye. The term is derived from the word "canthus," which pertains to the angle formed by the meeting of the eyelids.
When discussing the canthal area, it usually denotes one of two regions: the medial canthus or the lateral canthus. The medial canthus refers to the inner corner where the upper and lower eyelids meet closest to the nose, while the lateral canthus corresponds to the outer corner away from the nose.
In terms of its significance, the canthal region plays a crucial role in eye shape and function. It helps protect the eye from foreign particles, lubricates the surface of the eye, and assists in draining secretions. Additionally, the canthal angle is an anatomical characteristic studied in various medical and scientific fields, such as ophthalmology, plastic surgery, and forensic pathology.
Overall, the word canthal serves as a descriptive term used in medical and anatomical contexts to refer to the corners of the eyes where the upper and lower eyelids unite.

The term "canthal" is derived from the Latin word "canthus", which refers to the angle or corner of the eye where the upper and lower eyelids meet. The Latin word itself was borrowed from the Greek word "kanthos", which had a similar meaning. Thus, "canthal" is used to describe something related to or pertaining to the canthus, particularly in medical contexts, such as canthal ligaments, canthal angles, and canthal tendon.
