The pharyngeal plexus lies on the posterolateral wall of the pharynx, mainly over the middle pharyngeal constrictor and is the main motor and sensory nerve supply to the muscles of the pharynx and soft palate and acts to coordinate swallowing and speech 1–7.
What is a venous plexus?
A venous plexus is a congregation of multiple veins.
What is deep facial vein?
: a tributary of the facial vein that drains part of the pterygoid plexus and neighboring structures.
Which vein drains the danger area?
The danger zone on the face is a little triangle from the corners of the mouth up to the bridge of the nose. The reason it has such an epic name is because due to its venous drainage (from the facial veins and pterygoid plexus) there’s the possibility of infection traveling from that area into the cavernous sinus.
Is there a vein under your jaw?
Facial artery: This artery stems from the external carotid artery, follows the inferior border of the mandible, and enters the face. It provides blood to the muscles of the face. Submental artery: This artery starts from the facial artery and supplies blood to the tissues under the chin.
What is the purpose of a venous plexus?
A network of interconnecting veins. During SARPE with pterygomaxillary disjunction, damages to the venous plexus may lead to haemorrhagic complications due to short distance between the plexus and the osteotomy lines.
What are venous plexus foot pumps used for?
A device that alternates between applying pressure and no pressure on the sole of the foot. The change in pressure allows venous blood vessels to alternately fill and then empty, thus imitating the effects of walking on the veins of the lower extremities.
Where does prostatic venous plexus drain?
The receipt of blood from the vesical and prostatic rami connect the prostatic plexus to the vesical plexus and internal pudendal vein. The prostatic plexus then drains into the vesical and internal iliac veins.
What drains into pterygoid plexus?
The pterygoid plexus drains posteriorly into a . short trunk called the maxillary vein (fig. 1). The maxillary vein then courses posteroinferiorly and unites with the superficial temporal vein to form the retromandibular vein.
What is the Stylopharyngeus muscle?
The stylopharyngeus muscle is a long, slender and tapered longitudinal pharyngeal muscle that runs between the styloid process of the temporal bone and the pharynx and functions during the pharyngeal phase of swallowing.
What is retromandibular vein?
The retromandibular vein (temporomaxillary vein, posterior facial vein), formed by the union of the superficial temporal and maxillary veins, descends in the substance of the parotid gland, superficial to the external carotid artery but beneath the facial nerve, between the ramus of the mandible and the …
What is medial pterygoid?
The medial pterygoid muscle, a major elevator of the jaw is a square-shaped masticatory muscle, located on the medial aspect of the lower jaw bilaterally. It is also known as internal pterygoid muscle. This muscle lies medial to the lateral pterygoid muscle.
Which vein joins the superficial temporal vein?
Citation, DOI and article data. The superficial temporal vein arises in a plexus on the side and vertex of the skull and, in the substance of the parotid gland, joins with the maxillary vein to form the retromandibular vein.
What is the Infratemporal fossa?
The infratemporal fossa is a complex space of the face that lies posterolateral to the maxillary sinus and many important nerves and vessels traverse it. It lies below the skull base, between the pharyngeal sidewall and ramus of the mandible.
What is the venous pump?
muscle pump compression of veins by the contraction of skeletal muscles, forcing blood towards the heart against the flow of gravity; seen particularly in the deep veins of the lower limbs. Called also venous pump.
What is foot pumping?
This pumps blood back up to your heart. The A-V Impulse mimics the action of walking by inflating a small balloon that presses on the bottom of your foot. … Foot Pumps are clinically proven as a treatment for Deep Venous Thrombosis (DVT), a condition where a blood clot forms inside a vein that is deep inside the body.
Where does the plantar venous arch drain into?
It comprises two very large pedicles which are often duplicated: medial plantar veins and lateral plantar veins. Posteriorly, they drain into the posterior tibial perforating vein, which gives rise to the posterior tibial vein with a diameter of 5 to 6 mm.
Which plexus drains the ovaries?
In females, the pampiniform plexus drains the ovaries. The right ovary drains from the plexus to the ovarian vein and then to the inferior vena cava.
How does the pampiniform plexus regulate temperature?
The pampiniform plexus helps regulate the temperature of the testes by acting as a “heat exchange” mechanism to cool down the blood. The arteries supplying the testes run through the plexus where the blood is cooled from abdominal arterial temperature to testicular temperature.
What is venous drainage?
Venous drainage, anterior view. The systemic venous channels are further classified as superficial veins, deep veins, or venous sinuses. The superficial, or cutaneous, veins reside just beneath the surface of the skin. They channel blood from cutaneous tissues to deep veins via perforations in the deep fascia.
Can TMJ cause veins to bulge?
With temporomandibular joint syndrome, joints at the back of the jaw become inflamed, causing pain. Blood clots in the leg can become very dangerous, symptoms include swelling, redness, tenderness in the leg. Symptoms of varicose veins may include leg pain or aches and heaviness, noticeably swollen veins, and more.
Which artery carries blood to the brain?
The carotid arteries supply oxygen-rich blood to the brain. Plaque forms when the internal carotid arteries become blocked by fat and cholesterol buildup. This process is called atherosclerosis. Severe blockage is called carotid stenosis.
