Which vein is formed by the joining of the subclavian and internal jugular veins?
brachiocephalic veins
The brachiocephalic veins are formed at the confluence of the subclavian and internal jugular veins behind the sternoclavicular joints (see Figure 2.4). The right brachiocephalic vein is short, about 2–3 cm, and lies anterior to the innominate artery.
What vein leads to the internal jugular vein?
This vein runs in the carotid sheath with the common carotid artery and vagus nerve. It begins in the posterior compartment of the jugular foramen, at the base of the skull….
| Internal jugular vein | |

| Drains to | brachiocephalic vein |
| Artery | internal carotid, common carotid |

| Latin | vena jugularis interna |
What does the internal jugular vein join with?
The internal jugular veins unite with the subclavian veins to form the brachiocephalic veins and drain blood from the brain, the face, and the neck.
What does subclavian vein drain into?
The left subclavian trunk directly drains into the thoracic duct, and the right subclavian trunk continues to form the right lymphatic duct, which enters at the right venous angle (junction of the internal jugular vein and subclavian vein).
What vein connects subclavian and brachial veins?
| Axillary vein | |
|---|---|
| Drains from | axilla |
| Source | basilic vein, brachial veins, cephalic vein |
| Drains to | subclavian vein |
| Artery | axillary artery |
Is subclavian vein a central vein?
The subclavian veins are an often favored site for central venous access, including tunneled catheters and subcutaneous ports for chemotherapy, prolonged antimicrobial therapy, and parenteral nutrition.
How is internal jugular vein formed?
The internal jugular vein is formed by the anastomosis of blood from the sigmoid sinus of the dura mater and the common facial vein. The internal jugular runs with the common carotid artery and vagus nerve inside the carotid sheath. It provides venous drainage for the contents of the skull.
What is internal jugular vein?
The internal jugular vein is a paired venous structure that collects blood from the brain, superficial regions of the face, and neck, and delivers it to the right atrium. The internal jugular vein is a run-off of the sigmoid sinus.
How subclavian vein is formed?
Structure. Each subclavian vein is a continuation of the axillary vein and runs from the outer border of the first rib to the medial border of anterior scalene muscle. From here it joins with the internal jugular vein to form the brachiocephalic vein (also known as “innominate vein”).
What does the internal jugular vein drain?
The function of the internal jugular vein is to collect blood from the skull, brain, superficial parts of the face, and the majority of the neck. The blood collected from these vessels then drains to the brachiocephalic vein and into the right atrium.
Where does the axillary vein become the subclavian vein?
The axillary vein terminates by becoming continuous with the subclavian vein at the lateral border of the first rib 2.
Where does the subclavian vein start?
first rib
The subclavian vein originates at the outer border of the first rib. It travels within the subclavian groove, then runs laterally to the medial border of the anterior scalene. At this point, the subclavian vein joins with the internal jugular vein to form the brachiocephalic vein.
