Topic: Lateral pterygoid muscle


In the News (Fri 17 Feb 12)

  
  Mastication - Wikipedia, the free encyclopedia
Chewing food is a complex motor function, muscles need to be powerful enough to break tough portions of food, yet have enough dexterity to not injure the tongue, and to clear the mouth completely.
The primary muscles of mastication, each of which is paired, are the temporalis, masseter, medial pterygoid and lateral pterygoid.
It is thought that feedback from proprioceptive nerves in teeth and the temporomandibular joints govern the creation of neural pathways, which in turn determine duration and force of individual muscle activation (and in some cases muscle fibre groups as in the masseter and temporalis).

The lateral pterygoid plate is broad; its lateral surface forms the medial boundary of the infratemporal fossa, and affords attachment to the Pterygoideus externus.
Below and lateral to the anterior nasal aperture are the anterior surfaces of the maxillæ, each perforated, near the lower margin of the orbit, by the infraorbital foramen for the passage of the infraorbital nerve and vessels.
The lateral wall and the floor are separated posteriorly by the inferior orbital fissure which transmits the maxillary nerve and its zygomatic branch, the infraorbital vessels, and the ascending branches from the sphenopalatine ganglion.
