Jaw Crusher The Jaw Crusher is widely used in mining, building materials, chemical industry, metallurgy and so on. It is suitable for primary and secondary crushing of all kinds of minerals and rocks with compressive strength less than 320 MPa.
The structure of teeth All true teeth have the same general structure and consist of three layers. In mammals an outer layer of enamel, which is wholly inorganic and is the hardest tissue in the body, covers part or all of the crown of the tooth.
Dr. Brisbin: "The few studies which have been conducted of the structure of the skulls, mandibles and teeth of pit bulls show that, in proportion to their size, their jaw structure and thus its inferred functional morphology, is no different than that of any breed of dog.
Anatomical Structure. The mandible consists of a horizontal body (anteriorly) and two vertical rami (posteriorly). The body and the rami meet on each side at the angle of the mandible. Body. The body of the mandible is curved, and shaped much like a horseshoe.

Structure & function of teeth. The tooth has two anatomical parts. The crown of a tooth is that part of the tooth which is covered with enamel and this is the part usually visible in the mouth. The root is the part embedded in the jaw. It anchors the tooth in its bony socket and is normally not visible. Enamel The hard outer layer of the crown ...
The mandible, or lower jaw, is the bone that forms the lower part of the skull, and along with the maxilla (upper jaw), forms the mouth structure. Movement of the lower jaw opens and closes the ...
The structure of this part of anatomy is one of the most fascinating in human biology. The temporomandibular joint (TMJ) is the major joint in the jaw. This joint is named from the two bones that form the joint, and there is one TMJ on either side of the jaw.

If you already clench and grind your teeth, stress could make the habit worse. It can lead to problems with a joint known as TMJ that's located in front of your ear where the skull and lower jaw meet.
The mandible is the only bone in the entire skull that doesn't articulate with its adjacent skull bones via sutures. When the skull is observed purely as a bony structure, there is nothing anatomically holding the rest of the skull and the mandible together.
Several muscles involved in moving the jaw have insertion points along the mandible. The masseters form large insertions along the rami and coronoid processes to elevate, or close, the jaw. Insertions for the temporalis muscles, which also elevate the jaw, are found on the tips of the coronoid processes.
There have been a number of studies on the average and maximum jaw openings of different populations. Jaw Function Muscles Temporomandibular Joint

The temporomandibular joint is more commonly referred to as the TMJ joint, but what is TMJ? This joint is actually located at the base of the skull in front of the ear structure and connects the lower jaw (mandible) with the upper jaw (maxilla).
The upper part of the joint allows protrusion and retraction of the mandible – the anterior and posterior movements of the jaw. The lateral pterygoid muscle is responsible for protrusion (assisted by the medial pterygoid), and the posterior fibres of the temporalis perform retraction. A lateral movement (i.e. for chewing and grinding) is ...
The mandible, lower jaw or jawbone is the largest, strongest and lowest bone in the human face. It forms the lower jaw and holds the lower teeth in place. The mandible sits beneath the maxilla.It is the only movable bone of the skull (discounting the ossicles of the middle ear).
TMJ Anatomy The temporomandibular joint (TMJ) or jaw joint is a bi-arthroidal hinge joint that allows the complex movements necessary for eating, swallowing, talking and yawning. Dysfunction of the TMJ can cause severe pain and lifestyle limitation.
