What are the two 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.
Basilar artery is formed by the union of what two arteries?
vertebral arteries
The two internal carotid arteries unite on the base of the brain to form what?
the basilar artery.
What is the main artery that takes blood to the brain?
The left and right corotid arteries and the vertebral arteries which join together to form the basilar artery (forming the circle of willis).
What are the pathway of a drop of blood from the aorta to the left occipital lobe of the brain and What are the structures through which it flow?
The drop of blood travels as follows: From the aortic arch to the left subclavian artery. Then through the left vertebral, passing though the transverse foramina of the cervical vertebrae (from C6-C1) At the C1 level the vertebral arteries travel across the posterior arch of the atlas before entering the foramen magnum into the skull. From here, it merges with with that vertebral artery on the right side to become the basilar artery. The blood then travels through a branch of the basilar known as the posterior cerebral artery. This artery's branches are divided into two sets, the ganglionic branches and, the cortical branches. The particular artery largely supplying the occipital lobe is known as the parietoöccipital or parieto-occipital artery, and is a cortical branch.
What happens when to blood as it passes through brain?
vertebral arteries pass through foramen magnum and reach the inferior of the brain & unite to from the basilar artery. The vertebral artery supplies the posterior of the brain. Basilar atery branches into posterior cerebral artery & cerebellar arteries that supply the cerebellum & pons. Common carotid arteries divide & the internal carotid supplies structures internal to the skull

The posterior cerebral arteries serving the brain arise from here?

What is the artery resulting from fusion from of the left and right vertebrals?
The basilar artery is formed from the fusion of the left and right vertebral arteries at the base of the brainstem. It supplies blood to the brain and helps to form the posterior cerebral circulation.

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.
What is basilar migraine?
Basilar Migraine is a type of migraine that affects the basilar artery of the brain.
How do you use basilar in a sentence?
"The basilar artery is vital to the brain."
What structures pass through the various foramen?
The foramen magnum transmits the spinal cord, accessory nerves, vertebral arteries, and the anterior and posterior spinal arteries. The superior orbital fissure transmits oculomotor, trochlear, ophthalmic division of trigeminal, abducens, and ophthalmic veins. The optic foramen transmits the optic nerve and ophthalmic artery. And the jugular foramen transmits the glossopharyngeal, vagus, and accessory nerves, the internal jugular vein, and the sigmoid sinus.
