  Mandible - Wikipedia, the free encyclopedia
In insects, the mandible is an appendage near the mouth, typically acting as a jaw.
The mandible (inferior maxillary bone) (together with the maxilla) is the largest and strongest bone of the face.
The mandible consists of a curved, horizontal portion, the body, and two perpendicular portions, the rami, which unite with the ends of the body nearly at right angles.

In insects, the mandible is the segment forming the mouth.
In the posterior two-thirds of the bone the canal is situated nearer the internal surface of the mandible; and in the anterior third, nearer its external surface.
At its junction with the posterior border is the angle of the mandible, which may be either inverted or everted and is marked by rough, oblique ridges on each side, for the attachment of the Masseter laterally, and the Pterygoideus internus medially; the stylomandibular ligament is attached to the angle between these muscles.

If the mandible articulated on the basitemporal plate, the plovers would have two separate suspensions of the lower jaw--a condition unknown in all other recent tetrapods and one that is of extreme importance to studies on the evolution of the mammalian jaw articulation.
This arrangement of the articular surfaces of the mandible embracing the condyles of the quadrate serves to prevent sidewards or backwards displacement of the mandible.
A mass of eollagenous fibers eonneets the roedial proeesa of the mandible to the basieranium; this mass of eo!!agenous fibers is the basitemporal artieulation.

 Reasons Why the Piltdown Canine Tooth and Mandible Could Not Belong to Piltdown Man
Note the difference in the shape and direction of the transverse section at the cervical margin of the root: the major axis of the Piltdown tooth is in the mesio-distal direction, whereas in the human tooth it is in the opposite or labio-lingual direction.
In the much shorter human mandible lateral movement is considerably greater, and it permits the lower cheek teeth to cross (transgress) the buccal cusps of the upper teeth.
With the mandible mounted on a block of wax for stability, and with the direction of the ascending ramus the same as in the ape, place it on the paper so that the line C passes 2.5 mm.

 Medcyclopaedia - Mandible
The condyle of the mandible and the mandibular fossa constitute part of the temporomandibular joint.
In Caffeys disease the mandible may show new bone formation in soft tissue swellings directly contiguous to the cortex, sometimes reaching twice the usual width of the bone.
Fractures of the mandible frequently occur at more than one site in the bone; often a condylar fracture is associated with a fracture of the body or ramus.

 The Piltdown Mandible and Cranium
Indeed, in the moderately thick-skulled gorilla the mandible is massive, while among the moderately thick-skulled australopithecines the thickness and massiveness of the mandible may be, as in A.
Variability being what it is, it is not impossible that the mandible may belong with the cranium, but the disharmony in massiveness alone, not the mention the numerous other features, renders it high improbable that the mandible belonged to the same creature as disported the Piltdown cranium.
Hence, the occurrence of the mandible of an anthropoid in the same vicinity and contemporaneously with that of a fossil man as late as the Middle Pleistocene, and possibly the third interglacial, is a possibility somewhat less remarkable than has hitherto appeared.

It seems that for the mandible, by evaluating the experimental strain gradients, the form does not always follow the function, or at least not all parts of the mandible are designed as to maximize strength and minimize bone tissue (Daegling and Hylander 1997, Daegling 1993).
The mandible is vertically deep to counter the bending stress and transversely thick to counter the combined effects of torsion and direct shear.
The mandible presents a huge variation in geometrical and mechanical properties and therefore a variation in stress and strain values throughout the mandible is expected.

Miss Mandible wants to make love to me but she hesitates because I am officially a child; I am, according to the records, according to the gradebook on her desk, according to the card index in the principal's office, eleven years old.
Of the two I prefer, today, Sue Ann; although between eleven and eleven and a half (she refuses to reveal her exact age) she is clearly a woman, with a woman's disguised aggression and a woman's peculiar contradictions.
It may be that Miss Mandible also knows this, at some level, but for reasons not fully understood by me she is going along with the game.

The mandibular torus is found only on the lingual surface of the mandible, near the bicuspid teeth.
The buccal exostosis is found only on the facial surface of the alveolar bone, usually the maxillary alveolus.
Unless such a bony prominence is specifically located, is pedunculated or is associated with an osteoma-producing syndrome such as the Gardner syndrome, there may be no means by which to differentiate an exostosis from an osteoma, even under the microscope.

 Dave Amadio's Essay
How "Me and Miss Mandible" differs, in its narrative structure and character development, from works by O’Connor, Chopin, and Gordimer is perhaps the more pertinent issue when we discuss our responses to the story and its narrator.
By program of exhange we mean a ritual wherein characters, namely the narrator, Miss Mandible, Sue Ann, and Bobby Vanderbilt, actively construct their identities, their narrative "roles" from extisting texts, from selected cultural sign-systems, by reading and reproducing in their actions and attitudes a network of values readily pre-packaged for consumption.
Placing "Me and Miss Mandible" in a literary-cultural context demands we identify where we are, right now, as readers, and what we can do to dispel anxiety and confusion in our interpretive communities.
