The pterygoid plexus (/ ˈ t ɛ r ɪ ɡ ɔɪ d /; [1] from Greek pteryx, "wing" and eidos, "shape") is a fine venous plexus upon and within the lateral pterygoid muscle. It drains by a short maxillary vein .
One leg at a time. With the patient supine, empty the superficial veins by 'milking' the leg in the distal to proximal direction. Now press with your thumb over the saphenofemoral junction (2.5 cm below and 2.5 cm lateral to the pubic tubercle) and ask the patient to stand while you maintain pressure. If the leg veins now refill rapidly, the ...
The lateral pterygoid muscle (or external pterygoid muscle) is a muscle of mastication. It has two heads. It lies superior to the medial pterygoid muscle. It is supplied by pterygoid branches of the maxillary artery, and the lateral pterygoid nerve (from the mandibular nerve, CN V 3). It depresses and protrudes the mandible. When each muscle ...
The pterygomandibular space lies between the lateral surface of medial pterygoid and the medial surface of the mandibular ramus. The four compartents of the right masticator space. A Temporalis muscle, B Masseter muscle, C Lateral pterygoid muscle, D Medial ptaerygoid muscle, E Superficial temporal space, F Deep temporal space, G Submasseteric ...
It contains superficial muscles, including the lower part of the temporalis muscle, the lateral pterygoid muscle, and the medial pterygoid muscle. It also contains important blood vessels such as the middle meningeal artery, the pterygoid plexus, and the retromandibular vein, and nerves such as the mandibular nerve (CN V 3) and its branches.
The pharyngeal veins commence in the pharyngeal plexus superficial to the pharynx. The pharyngeal veins receive as tributaries meningeal vein , and the vein of the pterygoid canal . The pharyngeal veins typically empty into the internal jugular vein (but may occasionally instead empty into the facial vein , lingual vein , or superior thyroid ...
The maxillary artery, the larger of the two terminal branches of the external carotid artery, arises behind the neck of the mandible, and is at first imbedded in the substance of the parotid gland; it passes forward between the ramus of the mandible and the sphenomandibular ligament, and then runs, either superficial or deep to the lateral pterygoid muscle, to the pterygopalatine fossa.
The lateral pterygoid plate of the sphenoid (or lateral lamina of pterygoid process) is broad, thin, and everted and forms the lateral part of a horseshoe like process that extends from the inferior aspect of the sphenoid bone, and serves as the origin of the lateral pterygoid muscle, which functions in allowing the mandible to move in a lateral and medial direction, or from side-to-side.
