The superior cerebellar artery arises near the end of the basilar artery. [1] It passes laterally around the brainstem. [1] This is immediately below the oculomotor nerve, [1] which separates it from the posterior cerebral artery. It then winds around the cerebral peduncle, close to the trochlear nerve. It also lies close to the cerebellar ...
A cerebellar artery is an artery that provides blood to the cerebellum. Types include: Superior cerebellar artery; Anterior inferior cerebellar artery;
Three arteries supply blood to the cerebellum (Fig. 7): the superior cerebellar artery (SCA), anterior inferior cerebellar artery (AICA), and posterior inferior cerebellar artery (PICA). The SCA branches off the lateral portion of the basilar artery, just inferior to its bifurcation into the posterior cerebral artery. Here, it wraps posteriorly ...
The superior cerebellar artery; The fourth (IV) nerve; Crural cistern. It is situated around the ventrolateral aspect of the midbrain. It contains: The anterior choroidal artery; The medial posterior choroidal artery; The basal vein; Carotid cistern. It is situated between the carotid artery and the ipsilateral optic nerve. It contains: The ...
Within the cranium the two vertebral arteries fuse into the basilar artery. Posterior inferior cerebellar artery (PICA) Basilar artery: Supplies the midbrain, cerebellum, and usually branches into the posterior cerebral artery. Anterior inferior cerebellar artery (AICA) Pontine branches; Superior cerebellar artery (SCA) Posterior cerebral ...
Middle cerebral artery (MCA), which supplies blood to the majority of the lateral portion of the brain, including the temporal and lateral-parietal lobes. [ 2 ] [ 3 ] It is the largest of the cerebral arteries and is often affected in strokes [ 4 ]
The principal vascular structures coursing along the middle incisural space are the posterior cerebral artery and the superior cerebellar artery which pass around the brainstem, parallel to the free tentorial edge. The incisura has also a close relationship with the first 6 cranial nerves.
The tectum is supplied by the superior cerebellar artery. The central part of the tegmentum is supplied by the paramedian branches of the basilar artery. The lateral part of the midbrain is supplied by the posterior cerebral artery. Venous blood from the midbrain is mostly drained into the basal vein as it passes around the peduncle.
