What is mandibular fossa?

Mandibular fossa is a curved depression of a temporary bone of the skull. There are two of such cavities, with one on each side of the skull, so the phossae phrase is more suitable. Mandibular fossa is thus named because it is a depression located in the jaw commonly called the lower jaw. It is also called Glenoid fossa because of its shallowness or depth deficiency.

located on the base and sides of the skull and subsequently supports the sides of the head and eyes known as temples, the early bone is superior or physically placed above the jaw. Some of this, on each side of the skull, combines with the jaw to create a temporomandibular joint (TMJ). To create the joint, the joint disc is connected by a thin and oval plate composed of fibrous and cartilage tissue called joint disc and jaw.

Mandibular fossa works mainly as a part of the time bone that connects to the UPP articular discussion surface. To the joint of the joint disk is connected to the projection of the lower jaw called the mandibular condyl thatIt is separated from the coronoid process in front of the concave element, referred to as a mandibular notch. Mandibular fossa is therefore specifically responsible for unification or articulation, with mandibular condyle and plays an essential role in connecting the time bone with the lower jaw.

In the front is the boundary of Mandibular Fossa rounded projection filled with cartilage called joint tubercl or emintinetia articularis . The rear boundary of the mandibular fossa is the tymapanic part of the time bone. The curved bone element separates mandibular fossu from outer auditory meat or outer acoustic meat, which is better known as an ear canal. Pank on temporal bones called petrotympanic fissure & mdash; Also known as Glaser Pursure or Squamotympanic Pursure - divides the fossu in half.

within TMJ is mandibular fossa indirectly connected to two types of movement associated with the joint via SPOjení between temporary bone and lower jaw. The time bone is part of the upper area of ​​the joint and is involved in the wide opening of the jaw when it slides; This is referred to as translational movement. The cold, which is part of the lower compartment TMJ, helps in the initial opening of the jaw - the type of movement known as rotary movement.
