Inferior Internal Jugular Vein Bulb

Bulb of the internal jugular vein inferior (Bulbus Venae Jugularis Inferior, PNA): anatomical description and functions

There are many structures and organs in the human body that perform important functions to maintain its normal functioning. One of these structures is the bulb of the internal jugular vein (Bulbus Venae Jugularis Inferior, PNA). In this article we will look at the anatomical description and functions of this structure.

The bulb of the internal jugular vein inferior is an extension of the venous system that is located in the inferior jugular vein. It is located in the neck, close to the base of the skull and is part of the internal jugular vein system. The bulb is shaped like a small pouch or bulb, hence its name.

The functions of the inferior jugular vein bulb include:

1. Regulation of Blood Flow: The bulb plays an important role in regulating blood flow in the neck. It helps control the volume of blood entering the internal jugular vein system and the further distribution of this blood throughout the body.

2. Involvement in drainage: The bulb of the internal jugular vein also plays an important role in the drainage of blood from the brain and facial area. It collects venous blood from these areas and sends it to the internal jugular venous system and then to the body's venous system.

3. Participation in the pressure system: The inferior bulb of the internal jugular vein is involved in the regulation of venous pressure in the neck. It helps to control and maintain optimal pressure in the system of internal jugular veins, which affects the general condition of the body.

4. Transmission of information: The inferior internal jugular vein bulb also serves as some source of information about the state of the body. It may transmit signals related to blood flow and pressure in the internal jugular venous system, which can be used by the body to respond to various stressful situations or changes in the external environment.

In conclusion, the inferior internal jugular vein bulb is an important structure involved in regulating blood flow and draining venous blood from the brain and facial region. Its functions are related to maintaining optimal blood circulation and venous pressure in the neck, and also, possibly, transmitting information about the state of the body to the central nervous system.

The bulb of the internal jugular inferior vein is an anatomical formation on the surface of the neck, which is located between the hypoglossal and common carotid arteries, as well as the jugular process and the angle of the mandible.

The bulb is formed by two branches of the internal jugular vein: anterior and posterior. The branches join at the bottom of the neck to form a bulb, which is a reservoir for the accumulation of blood.

This is the most important vessel that nourishes the entire human body. It delivers oxygenated blood to the brain, kidneys, liver and other organs. Malfunction of the bulb leads to serious consequences and can cause serious disruptions in the functioning of the body.

Treatment of diseases of the bulb of the internal jugular inferior vein is surgical removal of the affected part or reconstruction of the vessels. Conservative treatment - drug therapy, lifestyle correction. It is recommended to eliminate pathological factors (if any) and carry out prevention.

The bulbous vein (bulbus veanae jugulares inferior) is a kind of whirlpool in the circulatory system, which is localized directly under the lower surface of the cartilaginous plate of the jugular veins. It is often also called the tubercle of the branch of the lower part of the ascending vertebral artery. This anatomical formation was described by the English physician William Humphrey in 1615. It is believed that the term itself was taken from the Latin language, namely “bulbus” and “jugular”. The literal translation means “bulb vein.” The term “bulbous node” has many synonyms. For example, a blood bulb or a bulbous medullary node. Today they are usually used only in medical fields, to refer to the same organ. However, if we take the definition of this blood tubercle literally, it really resembles an onion from the large intestine.

The anatomical concept of “inferior internal jugular vein” Jugular veins, like everything else in the human body, have their own classifications. Essentially, this vessel is used as a venous pathway that carries blood away from the head and neck. The inferior veins of the jugular foramen are localized in the muscles of the neck and join the jugular veins by a large fibrous process passing through the ossified vertebral body. In addition, the transverse and lingual veins, located on both sides of the neck, flow into it. It is also connected to the vagus nerve through a sympathetic ganglion of fibers. The outflow of blood through this large circulatory system is carried out into the angle of the inferior jugular vein.

The structure of the bulb, the internal jugular inferior vein, usually includes: - an enlarged segment of the Douglas artery; - fibers of the nervous system going to the brain; - shells of the skull skeleton; - muscle structures of the neck; - the cell itself is inferior jugular; - arterioles, internal arteries of the brain; - external muscles that supply blood to the periphery.

The superior vein of the bulb is located on the body of the thoracic spine. The apical part of the jugular region is located behind the jugular arch and is attached to these glands by the external superficial muscles. The dome-shaped dimple can become a mechanical obstruction, restraining pressure on the inferior bulb. Thanks to the complex tubular formations of the skeletal muscles of the neck, ligaments and transverse muscle complex, injuries to the head area, adjacent areas and vessels going inside the skull become impossible. This important organ holds the pulsating waves of the central arteries of the head. In other words, it plays no small role in the physiological sense.

However, it also has a pathological function. Neoplasms are often diagnosed because the superior and inferior veins pass close to the central artery of the brain. When the ascending portal of the central nervous system is blocked, blood circulation is disrupted and thrombosis or embolism of internal capillaries occurs. Improper blood flow in the head can lead to strokes or other malignant diseases. Such diseases do not go away without consequences and significantly affect a person’s quality of life. After all, normal blood flow ensures a complete exchange
