The pontine branches are the small arterial branches of the basilar artery that supply the pons and structures adjacent to the pons. There are usually 3-5 paired arterial branches which are located in the mid-basilar region between the anterior inferior cerebellar artery and the superior cerebellar artery.Mar 25, 2009
Anatomical terms of neuroanatomyIn the human brain, the superior cerebellar peduncle (brachium conjunctivum) is a paired structure of white matter that connects the cerebellum to the midbrain.
The pontine arteries are a number of small vessels which come off at right angles from either side of the basilar artery and supply the pons and adjacent parts of the brain.
The three major arteries of the cerebellum: the SCA, AICA, and PICA.
Rostrally, blood flow comes from the basilar artery and anterior inferior cerebellar artery (AICA).
The frontal cortex receives its blood supply from two branches of the internal carotid artery: the anterior cerebral arteries and the middle cerebral arteries. The superior and medial aspects of the cortex receive its supply from the smaller anterior cerebral artery.Jun 10, 2021
Among the most important dorsal-lateral arteries (also called long circumferential arteries) are the posterior inferior cerebellar artery (PICA) and the anterior inferior cerebellar artery (AICA), which supply distinct regions of the medulla and pons.
The internal capsule and basal nuclei are supplied by perforating branches of the anterior cerebral artery (ACA), Heubner's artery, middle cerebral artery (MCA), internal carotid artery (ICA) and anterior choroidal artery (AChA).
: any of three large bands of nerve fibers that join each hemisphere of the cerebellum with the parts of the brain below and in front: a : one connecting the cerebellum with the midbrain.
The cortical branches of PCA supply the posterior medial parietal lobe and the splenium of the corpus callosum, inferior and medial part of the temporal lobe including the hippocampal formation, and the medial and inferior surfaces of the occipital lobe.
The circle of Willis, which is located at the base of the brain, is supplied by the internal carotid and vertebral arteries, and it regionally distributes blood flow to the cerebral cortex. The middle cerebral artery carries nearly 80% of the flow to the cerebral hemispheres.
The oculomotor nerve usually passes between the P1 segment of the PCA and the SCA. The portion of PCA from the posterior communicating artery to the posterior edge of the midbrain is termed the P2 segment.Jul 5, 2018
The anterior cerebral artery supplies the frontal lobes and medial aspects of the parietal and occipital lobes. The middle cerebral artery, also called the artery of stroke, supplies the frontoparietal somatosensory cortex.Jan 21, 2002
The superior cerebellar artery delivers oxygenated blood to the superior (upper) part of the cerebellum, located behind the top of the brain stem, and some locations within the midbrain.Jan 20, 2018
