Venous Plexus Pterygoid

Venous plexus pterygoid: anatomical formation and its role

The pterygoid venous plexus (p. v. pterygoideus, pna, bna, jna) is a complex vascular formation located in the region of the pterygoid process of the maxillary bone. This anatomical element plays an important role in the venous circulation of the head and neck.

The anatomy of the pterygoid venous plexus is characterized by a complex network of veins formed in the area of ​​the pterygoid process. The main components of this plexus are the pterygoid veins (p. v. pterygoideus), which run along the lateral surface of the pterygoid process. They collect venous blood from a number of veins in the head and neck and send it to larger veins in the facial and cervical regions.

The pterygoid venous plexus is also connected with the posterior pterygoid veins (pna), which pass in the deep region of the pterygoid process. They come into contact with other veins of the head and neck, providing additional routes for the outflow of blood.

In addition, the pterygoid venous plexus has a connection with the lateral posterior veins (bna), which pass in the posterior part of the pterygoid process. These veins take part in collecting venous blood from deep areas of the head and neck and direct it to the venous sinuses.

Finally, the pterygoid venous plexus is connected with the posterior jugular veins (jna), which pass in the region of the jugular process of the maxillary bone. These veins collect venous blood from the jugular vein and transmit it to other venous structures of the head and neck.

The venous pterygoid plexus plays an important role in the drainage of blood from the head and neck. It ensures efficient flow of venous blood collected from various areas of this part of the body. This is especially important in the context of surgical procedures involving this area, such as tumor removal or facial reconstructive surgery.

In conclusion, the pterygoid venous plexus is a complex anatomical structure that plays an important role in the venous circulation of the head and neck. Its connections with other venous structures ensure optimal outflow of venous blood and are of practical importance for surgeons and medical specialists working in this field. Further research into the anatomy and function of the pterygoid venous plexus will help to better understand its role and impact on overall human health.

Venous plexus of the pterygoid canal

The venous arterial wing is a layer of tissue that is located between the temporalis muscle and the pterygoid process of the sphenoid bone. It is formed from lymphatic vessels that supply the palate and maxillotemporal bone.

Functions

The main function of the venous node of the pterygoid plexus is to provide lymphatic drainage from the jaw apparatus. In addition, this education performs a number of other tasks:

* formation of anastomoses; * ensuring active lymph flow in tissues; * cleansing the body of metabolic products; * prevention of pathological processes in the oropharynx; * increasing bone strength under mechanical stress.

To understand how the venous winged plexus works, it is important to know each of its components.

If the muscle fibers branch in a horizontal direction, then in one cavity, surrounded by veins, you can see a chain of large lymph nodes. These nodes work on a waterfall principle to reduce the risk of inflammation.

An important component of the venous-lymphatic node is anastomosis. This is the place where the superficial and deep lymphatic vessels connect; Moreover, connections from several neighboring structures occur simultaneously in this area. This principle reduces the likelihood of stagnant processes in this place.

It is also worth noting that the pterygoid venous branching is located behind the temporal crest, providing a connection between the apex of the uvula and the hypoglossal foramen. That is, the lymph makes its way through the tongue, then down along the jaw, and then rises above the upper part of the same lower jaw through the pterygoid vein. Therefore, the pressure in the tissues decreases.

To form the venous valve, the venous node is shaped on the reverse side of the convex head of the penis. This kind of protrusion reduces the force of the flow of blood flowing here. Due to this subcapsular location, venous blood thickens and its outflow is greatly slowed down. At the same time, the expansion of blood capillaries in adjacent tissues occurs.

In addition, lymphatic capillaries are also located in this area. Lymphatic valves serve to regulate the flow rate, prevent kinks and reverse movement of lymph. Lymphocytes function on the principle of point shock absorption and facilitate the passage of lymphatic transport. The adjacent walls form a large number of pockets of different sizes, including deep and superficial channels.

The lymphatic system of the pterygopalatine process also includes many capillary slits and capillary sacs to increase lymph compression and reduce inflammation in this area. This is what allows the tissues of the jaw system to remain passable and provide the body with the necessary fluid.
