    Transcript
    Now, we’ll move on and take a look at the subclavian artery. There are four branches associated with the subclavian artery. The first and a very significant branch is the vertebral artery that we see in through here. It will help supply blood to the brain along with the internal carotids that we mentioned earlier. Second branch of the subclavian artery is a trunk. This is referred to as the thyrocervical trunk. We see it issuing from the right subclavian in this area. The third branch is the costocervical trunk. This is a smaller branch that we see in through here. As the name implies, this will help to supply the ribs, the upper two ribs. Then it has an outstanding course to help supply cervical-related structures. Then your fourth and final branch is a descending branch. This is your internal thoracic artery. It’s descending along the lateral margin of the sternum. Of the branches of the subclavian artery, the vertebral artery is important in that it supplies, with the assistance of the internal carotids, it supplies the brain with blood. The vertebral artery has a curious course to help to supply the brain with blood and that it will pass through the transverse foramina of the cervical vertebrae. There are variations on how it does so. The most common is for the vertebral artery that we see here to pass through the transverse foramen of C6. It will then ascend through all the other sequential transverse foramina until it passes through the one associated with C1. It then will curve medially and then loop upwards through the foramen magnum to help supply the brain with blood. In 5% of the cases, the vertebral artery will skip the transverse foramina of C7 and C6 and enter at the level of...
