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].

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.

The presence of canal in clivus might interfere with neurosurgical operations in the clival region and possibly provoke symptoms of the basilar artery, as well as of the basilar plexus.2 In a study, bony canal was found on the lower half of the clival surface in 3 out of 100 adult cranial bases studied and named inferior median clival canal" to this anatomical variation.3
