bas·i·lar ar·ter·y

[TA]
formed by union of the intracranial portions of the two vertebral arteries; runs along the clivus in the subarachnoid space from the lower to the upper border of the pons, where it bifurcates into the two posterior cerebral arteries; branches, anterior inferior cerebellar artery [TA], pontine arteries [TA], mesencephalic arteries [TA], superior cerebellar artery [TA], and posterior cerebral artery [TA].
Synonym(s): arteria basilaris [TA]

basilar artery

the single posterior arterial trunk formed by the junction of the two vertebral arteries at the base of the skull. It extends from the inferior to the superior border of the pons before dividing into the left and right posterior cerebral arteries. It supplies the internal ear and parts of the brain. Its branches are the pontine, labyrinthine, anterior inferior cerebellar, superior cerebellar, and posterior cerebral.

basilar artery

An artery in the base of the brain formed by the union of the right and left vertebral arteries, which courses along the clivus from the lower to upper borders of the pons, and bifurcates into the posterior cerebral arteries. The basilar supplies the pons, vertebral arteries, and provides branches to the cerebrum and cerebellum.

bas·i·lar ar·te·ry

(bas'i-lăr ahr'tĕr-ē) [TA]
Formed by union of the intracranial portions of the two vertebral arteries; runs along the clivus in the pontine cistern of the subarachnoid space from the lower to the upper border of the pons, where it bifurcates into the two posterior cerebral arteries; branches, anterior, inferior, cerebellar, labyrinthine, pontine, mesencephalic, and superior cerebellar.
Synonym(s): arteria basilaris [TA] .

basilar artery

An important artery formed from the junction of the two vertebral arteries that run up through the side processes of the vertebrae of the neck. The basilar artery runs up in a groove on the front surface of the PONS to supply most of the BRAINSTEM and CEREBELLUM and then joins the arterial circle, the circle of Willis, on the base of the brain.

basilar

pertaining to a base or basal part.

basilar artery
one of the main blood supplies to the brain. It originates from the junction of the two vertebral arteries, runs in a median groove, beneath the medulla and pons, and terminates rostrally at the cerebral circle (of Willis). See also Table 9.
basilar fracture
at the base of the skull, usually involving the occipital and basisphenoid bones.
