What is the vertical section of the mandible called?

What is the vertical section of the mandible called?

The rami are two vertical processes located on either side of the body; they join the body at the angle of the mandible. At the superior aspect of each ramus, the coronoid and condylar processes articulate with the temporal bone to create the temporomandibular joint which permits mobility.

What is the main part of the jaw called?

It consists of two main parts. The upper part is the maxilla. It doesn’t move. The moveable lower part is called the mandible.

What is a two part mandible?

Now we’ll bring the mandible into the picture. The mandible develops from two originally separate bones, one on each side, which fuse together here at the symphysis. The mandible is described as consisting of the body, and the right and left ramus. The corner between the ramus and the body is the angle of the mandible.

What is the difference between mandible and maxilla?

As nouns the difference between maxilla and mandible is that maxilla is either of the two bones that together form the upper jaw while mandible is the lower jaw, especially the lower jawbone.

What do you call the lower jaw bone?

The mandible (lower jawbone).

What is the vertical part of the mandible called?

The horizontal portion, bearing the teeth, is called the body; the vertical to oblique posterior portion is the ramus (plural, rami); and these two portions meet at a corner called the angle of mandible.

Where are the hollow spaces in the mandible?

The edges of this part rise up to make up the mental tubercle. To the side of this, and below the incisive (front) teeth is a depression called the incisive fossa, and there is an opening on each side adjacent to the premolars called the mental foramen. The upper border, also known as the alveolar border, contains hollow spaces for the teeth.

When does the mandible become part of the chin?

The mandible develops as separate right and left bones in the fetus, joined by a median cartilaginous joint called the mental symphysis at the point of the chin. This joint ossifies in early childhood, uniting the two halves into a single bone. The point of the chin itself is called the mental protuberance.

Is the mandible the largest bone in the face?

In addition, corrective surgeries may be performed on the mandible to correct misalignment due to improper development of the jaw. The largest facial bone, the mandible is roughly horseshoe-shaped, defining the lower margins and sides of the face. Anatomically speaking, it’s divided into two major sections: the body and the ramus.
