mandibulo-, mandibul-, mandibuli-; manduc-, manduca-
(Latin: jaw, lower jaw; chew; from mandere, "to chew")
2. Either the upper or lower part of the beak in birds.
3. Any of various mouth organs of invertebrates (no backbones or spinal columns) used for seizing and biting food; especially, either of a pair of such organs in insects and other arthropods (creatures that have jointed legs, bodies divided into several parts, and their skeletons on the outside).
4. Etymology: "jaw, jawbone" from Late Latin mandibula, "jaw" from Latin mandere, "to chew".
Mandible is a transliteration of the Latin mandibula, "the lower jaw". The word comes from the Latin verb mandere, "to chew"; the anatomists used maxilla for both the upper and the lower jaws, and only much later did the "inferior maxilla" become the "mandible".
Mandible, "jaw"; especially, the lower jaw, 1392, borrowed from Old French mandible, and directly from Late Latin mandibula, from Latin mandere, "to chew", cognate with Greek mathyiai, "jaws".
Its functions include the protection of the tongue and it is involved in speech, biting, and the grinding of food in a person's mouth so it will become soft enough to swallow.
The mandibula has also been referred to as the:
- lower jaw
- inferior jaw
- jaw bone
- inferior maxilla
- lower jaw bone
- inferior maxillary bone
Mandibulectomies can be either marginal, in which only the bone, teeth, and adjacent soft tissues are resected and the mandible's continuity is maintained; or segmental, where a complete segment of the mandible is removed.
An arthropod is an invertebrate (no back bone) that has jointed limbs and a segmented body with an exoskeleton or outer skeleton made of a tough semitransparent horny substance; such as, with insects.
The pharynx is cone shaped and is lined with mucous membrane and it opens into the oesophagus (esophagus) at the lower end.
People also manducate when they are satisfying their appetites during meals or snacks.2. Etymology: from Latin manducare, "to chew".
