The retromandibular vein (temporomaxillary vein, posterior facial vein) is a major vein of the face. It is formed within the parotid gland by the confluence of the maxillary vein, and superficial temporal vein. It descends in the gland and splits into two branches upon emerging from the gland.
Diagram showing left medial and lateral pterygoid muscles. Part of the zygomatic arch and the ramus of the mandible have been cut away. The pterygomandibular space lies between the lateral surface of medial pterygoid and the medial surface of the mandibular ramus.
The external jugular vein is a paired jugular vein which receives the greater part of the blood from the exterior of the cranium and the deep parts of the face, being formed by the junction of the posterior division of the retromandibular vein with the posterior auricular vein.
The infratemporal fossa is an irregularly shaped cavity that is a part of the skull.It is situated below and medial to the zygomatic arch.It is not fully enclosed by bone in all directions.
From its origin it runs obliquely downward and backward, beneath the zygomaticus major muscle and zygomatic head of the levator labii superioris, descends along the anterior border and then on the superficial surface of the masseter, crosses over the body of the mandible, and passes obliquely backward, beneath the platysma and cervical fascia, superficial to the submandibular gland, the ...
The pterygomandibular raphe (pterygomandibular fold [1] or pterygomandibular ligament) is a thin [2] tendinous band of buccopharyngeal fascia.It is attached superiorly to the pterygoid hamulus of the medial pterygoid plate, and inferiorly to the posterior end of the mylohyoid line of the mandible.
The maxillary vein or internal maxillary vein is a vein of the head.It is a short trunk which accompanies (the first part of) the maxillary artery.It is formed by a confluence of the veins of the pterygoid plexus.
The movement area of the mandible in the sagittal and horizontal planes is characteristic of the individual but varies in different persons. However, the border movement paths are reproducible in the same individual. It is suggested that the temporomandibular joints (TMJ) limit the border movements of the mandible.
