vertebral arteries
The left & right vertebral arteries.
The vertebral arteries are branches from the subclavian arteries that travel up the spine in the foramen transversarium and into the skull in the formen magnum. They fuse at the level of the midbrain to form the basilar artery and then the posterior cerebral arteries. They supply blood to the brainstem, cerebellum and posterior portions of the brain.
cervical vertebral c5-6
They supply the brain (and structures of the head, as well) with oxygenated blood.
vertebral arteries
The anterior portions of the brain are supplied by the internal carotid arteries. The posterior portion of the brain is supplied by the vertebral arteries.
The left & right vertebral arteries.
The right and left vertebral arteries join together to form a single basilar artery at the base of the skull.
Tranverse formamina
Oxygen and nutrients are provided to the brain via the carotid arteries and vertebral arteries.
The statement "The vertebral arteries are patent bilaterally throughout their course" indicates that both vertebral arteries, which run along the spine and supply blood to the brain, are open and unobstructed on both sides of the body. This suggests that there are no blockages or abnormalities affecting the blood flow in these arteries. A patent condition is essential for adequate blood supply to the posterior circulation of the brain.

cervical vertebral c5-6
The major arteries involved include 1) the right and left carotid arteries, and 2) the right and left vertebral arteries.
The internal carotid arteries and the vertebral arteries are the primary vessels that supply oxygenated blood to both sides of the brain. The internal carotid arteries branch into the anterior and middle cerebral arteries, while the vertebral arteries join to form the basilar artery, which supplies the posterior part of the brain. These arteries collectively ensure a rich supply of oxygenated blood, supporting brain function and health.
Carotid arteries supply blood to brain . Blood is supplied to the entire brain by 2 pairs of arteries: the internal carotid arteries and vertebral arteries. The right and left vertebral arteries come together at the base of the brain to form a single basilar artery. The basilar artery joins the blood supply of the internal carotid arteries in a ring at the base of the brain. This ring of arteries is called the circle of Willis. The circle of Willis provides a safety mechanism...if one of the arteries gets blocked, the "circle" will still provide the brain with blood.
