Jugular vein superficial ventral: anatomy and functions

The superficial ventral jugular vein (abbreviated JNA) is one of the veins located in the neck. It plays an important role in the circulatory system, ensuring the outflow of blood from the head and neck.

The anatomy of the superficial ventral jugular vein includes its passage along the anterior surface of the neck, parallel to the jugular vein, which is located deeper. The JNA is formed from numerous venous junctions that collect blood from various areas of the face, neck and head.

The function of the superficial ventral jugular vein is to collect blood, rich in waste metabolic products and carbon dioxide, from the superficial tissues of the head and neck. This blood then drains through the JNA, heading into additional veins and ultimately back into the superior vena cava system, the main vein of the upper thoracic cavity.

It is important to note that the superficial ventral jugular vein can be susceptible to various diseases and conditions, including thrombosis, inflammation and compression. This can interfere with normal blood flow and cause symptoms such as swelling, tenderness, and discoloration of the skin in the neck and face.

In some clinical situations, the JNA may be used as a vascular access for medical procedures such as administering medications or collecting blood for testing. This is due to its relative ease of accessibility and clearly distinguishable anatomy.

In conclusion, the superficial ventral jugular vein plays an important role in the circulatory system by draining blood from the head and neck. Understanding its anatomy and functions is of great importance for medical practice and can help in the diagnosis and treatment of related conditions.

Jugular vein: superficial and deep

The jugular vein (jugularis) is one of the main vessels through which blood from the head enters the right atrium of the heart. It lies in a special canal - the jugular fossa, lined with a dense fibrous membrane, due to which it practically does not move when the head moves. In anatomy, it is customary to distinguish two variants: superficial and deep. They will be discussed in this article.

Superficial vein Otherwise known as the suprasternal vein. Lies at the level of the opening of the manubrium of the sternum in the back of the neck; for better visualization, you can move the thyroid cartilage and find the junction of the throat with the neck. You will usually immediately notice that the vein in your neck is red and pulsates under your fingers when you feel it. That’s right – this is it, the superior jugular vein. Its purpose is to transport blood from the skull to the heart.

On the right side of the superficial vein there are two
