The medial pterygoid nerve (or internal pterygoid nerve) is a branch off the mandibular nerve that innervates the medial pterygoid muscle. Latin is an ancient Indo-European language originally spoken in Latium, the region immediately surrounding Rome. ... The medial pterygoid is a muscle of mastication with two heads. ... The Tensor veli palatini muscle (or Tensor palati) is a muscle of the human body. ... The mandibular nerve is the third branch (V3) of the trigeminal nerve. ... Elseviers logo. ... The mandibular nerve is the third branch (V3) of the trigeminal nerve. ... The medial pterygoid is a muscle of mastication with two heads. ...

Structure

The nerve to the medial pterygoid muscle is a slender branch of the mandibular nerve which enters the deep surface of the muscle; it gives off one or two filaments to the otic ganglion. The medial pterygoid is a muscle of mastication with two heads. ... The mandibular nerve is the third branch (V3) of the trigeminal nerve. ... The Otic Ganglion is a parasympathetic ganglion located immediately below the foramen ovale. ...


The nerve provides physical support for the otic ganglion, but is neurologically distinct. The Otic Ganglion is a parasympathetic ganglion located immediately below the foramen ovale. ...

It presents medially the trochlear fovea for the attachment of the cartilaginous pulley of the Obliquus oculi superior; laterally, the lacrimal fossa for the lacrimal gland; and posteriorly, the suture between the frontal bone and the small wing of the sphenoid.
At the junction of the medial wall and the roof are the frontomaxillary, frontolacrimal, frontoethmoidal, and sphenofrontal sutures.
In the frontoethmoidal suture are the anterior and posterior ethmoidal foramina, the former transmitting the nasociliary nerve and anterior ethmoidal vessels, the latter the posterior ethmoidal nerve and vessels.
Mastication - Wikipedia, the free encyclopedia (471 words)
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).
It is thought that conscious mediation is important in the limitation of parafunctional habits as most commonly, the motor program can be excessively engaged during periods of sleep and times of stress.
