Definition of Labial
Labial definition - medical term
Pertaining to the lip, one of the fleshy folds which surround
the opening of the mouth or the vagina.
< u>Oral Labia: The upper lip is separated from the nose by the philtrum,
the area that lies between the base of the nose and the pigmented edge (called the
vermillion border or the carmine margin) of the upper lip. The upper and lower lips
meet at the corners (or angles) of the mouth which, in anatomy, are called the oral
commissures. The oral commissure normally lies in a vertical line below the pupil.
Small blind pits are sometimes seen at the corners of the mouth; they are known
as angular lip pits and are considered normal minor variants.
The lips may be abnormally thin or thick. For example, the upper lip is typically
thin and the philtrum flat in children with the fetal alcohol syndrome. If the upper
lip is overgrown, the corners of the mouth appear to be downturned.
Labial Sounds definition - medical term
The lips are not only anatomic features of note, they are
organs of speech essential to certain articulations. A sound requiring the participation
of one or both lips is a labial (labium in Latin means lip) sound or, simply, a
labial. All labials are consonants. There are bilabial sounds such as "p" which
involve both lips and labiodental sounds such as "v" which involve the upper teeth
and lower lip.
Vaginal Labia definition - medical term
There are two pairs of labia (lips) at the entrance to
the vagina. They are the labia majora (the larger outside pair) and the labia minora
(the smaller inside pair). Together they form part of the vulva (the female external
genitalia).
The Word "Labia" definition - medical term
The word "lip" can be traced back to the Indo-European
"leb" which also produced the Latin "labium" from which came the French "levre."
The German "lippe" is just a slip from the English "lip." See also: Labrose.
