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.

Basilar artery is formed by the union of what two arteries?
vertebral arteries
The basilic artery in the brain receives blood from what two arteries?
The left & right vertebral arteries.
How many vertebral arteries do humans have?
2
What level of neck does the carotid arteries bifurcate?
cervical vertebral c5-6
What are the two pairs of arteries that supply the brain?
It is the Internal carotid and the vertebral arteries. The vertebral arteries join to form the basilar artery which supply the midbrain and the cerebellum. The internal carotid branches divides to form the left and right internal carotids which supply the left and right side of the brain respectively. Hope this helps...feel free to ask if you don't understand. cheers Faith

What two paired arteries enter the skull to supply the brain?
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.

What supplies blood to brain?
Blood is being transported to the brain through two arteries namely internal carotid and vertebral arteries. These two arteries are a part of the dorsal aorta that also supplies blood to the spinal cord.

Which vessel is formed when the vertebral arteries join together at the base of the skull?
The right and left vertebral arteries join together to form a single basilar artery at the base of the skull.
Passageway for vertebral arteries in cervical vertebrae?
Tranverse formamina
Provides the brain with oxygen and nutrients?
Oxygen and nutrients are provided to the brain via the carotid arteries and vertebral arteries.
What level of neck does the carotid arteries bifurcate?
cervical vertebral c5-6
What blood vessel conducts blood to the head?
The major arteries involved include 1) the right and left carotid arteries, and 2) the right and left vertebral arteries.
What is the path of blood from the left ventricle to the brain?
Blood vessels that supply the brain are the two carotid arteries and the two vertebral arteries.- From the left ventricle, blood flows into the aorta and the common carotid arteries supply the frontal portion of the brain through the inner carotid arteries, which lead to blood vessels such as the three pairs of cerebral arteries (anterior, middle, posterior).- From the left ventricle, blood flows from the arch of the aorta into the paired subclavian arteries, and then to the vertebral arteries, which supply the rear and lower parts of the brain through the basilar artery (which ends at the posterior cerebral arteries).* Within the brain, cross-connections between these arteries (called the Circle of Willis) provide some redundancy should any of the arteries become severed or blocked.
