Muscles of mastication are called so because they are involved in the complex process of mechanical grinding of food. They also provide movement of the lower jaw. Due to this, a person can close and open your mouth to talk, yawn, etc. Chewing muscles fixed to the bones as well as others. They are fixed the two ends. The movable portion of the muscle is fixed on the lower jaw. Fixed is fixed on the bones of the skull. All the muscles involved in chewing and movement of the lower jaw, have the same structure. They present the muscular part. It can be reduced and allow the lower jaw to move. lateral pterygoid muscle

Types

The Masticatory muscles are much smaller than, for example, mimic. First of all 4. However, they perform essential functions, including providing preservation "angle of youth." These include the muscles,

  1. Temporal.
  2. Chewing.
  3. Lateral and medial pterygoid.

All these elements form a single structure. When shortening or deformation of one of them are subject to changes and others.

The Lateral pterygoid muscle: a picture, a brief description

It has two heads. They are separated by their own connective sheath (fascia). The Lateral pterygoid muscle starts from the bone At the base of the skull. The beams depart from different points. More narrow (the upper) is of the infratemporal region of the greater wing to the sphenoid bone, and from the infratemporal crest. The wider (lower) the beam goes sideways. It starts from the lateral pterygoid plate of the sphenoid bone. The fibres unite in the achievement of its holder. lateral pterygoid muscle starts from the bone

The Lateral pterygoid muscle: function

I Should say that this element of the muscles has various relationship with other facial structures. If l< / span>Feralina pterygoid muscle Will begin to function poorly or will be subjected to deformation, it can affect the activities of other systems. Dysfunction of this element can cause a variety of symptoms and disorders, even loss of hearing. Lateral pterygoid muscle provides the extension of the jaw. This is achieved while reducing the beams on the right and left. If the Lateral pterygoid muscle involved on only one side, the jaw is shifted in the opposite direction. For example, when the reduction of the right beam it moves to the left, and Vice versa. lateral pterygoid muscle photo

Media element

This muscle is presented in the form of a quadrangle. It acts as an essential element of the mandibular ligament. Is the muscle on the inner surface of the bone, chewing on the contrary, in the same direction with it. In some cases, their beams unite. Fixed element by means of thick spikes. Only two of them. Larger attached to the wing side of the sphenoid bone, lesser – pyramidal process of the palatal part and the tuber in the upper jaw. At the bottom of the muscle is fixed in the two points. Between the appendages is formed by many important structures. Among them the nerves, alveolar, maxillary vessels. The medial element, as well as Lateral pterygoid muscle, provides movement of the lower jaw. With the reduction on both sides of the bone moves forward and up, on the one hand – in the side.

Chewy

This muscle is located on top of the pterygoid (medial and lateral). It is strong enough, as trains often during mastication. Its contours well enough to be felt, especially when she is in a reduced condition. The muscle is fixed to the zygomatic arch. It has a quite complex structure. Muscle fibers are divided into deep and superficial parts. The last one departs from the middle and front sections of the zygomatic arch. The deep part is attached a little further. It departs from the rear and middle sections of the arc. Surface element runs at an angle back and down. However, he covers a portion, located deep. lateral pterygoid muscle functions

Temporal element

This muscle moves against three bones. The temporal element takes up almost 1/3 of the surface of the skull. The shape of the muscle is like a fan. The fibres go downwards and go into quite a powerful tendon. It is fixed on the coronal process of the mandible. This muscle provides kostelny movement. In addition, it pulls the lower jaw forward and also lifts it to the closure with the top. The temporal jaw is not a pronounced relief. However, it is directly involved in the formation of the "sunken temples". With weight loss or frequent nervous stress a muscle receives more than thin and flat shape. The temporal line and zygomatic arch thus gain relief. In this case, the person looks exhausted. Dysfunction or spasm is very difficult to detect changes in it.
