Which of the following blood vessels supplies the anatomical region indicated by the blue arrow in the image below?
[lightgallery]

Options:
explanation: The image shows a prosection of the cerebellum from a basal view, with the cerebellar hemispheres on each side of the image and the brainstem at the top of the image. The blue arrow indicates the posterior lobe, the most extensive lobe of the cerebellum, located inferior to the horizontal fissure. Its vascular supply is provided by the posterior inferior cerebellar artery, a branch of the vertebral artery on each side.
name: Posterior inferior cerebellar artery
label: a
answer: yes
explanation: The image shows a prosection of the cerebellum from a basal view, with the cerebellar hemispheres on each side of the image and the brainstem at the top of the image. The anterior inferior cerebellar artery supplies the deep aspects of the cerebellar hemispheres. It is a branch of the basilar artery. However, the blue arrow indicates the posterior lobe, the most extensive lobe of the cerebellum, located inferior to the horizontal fissure. Its vascular supply is provided by the posterior inferior cerebellar artery, a branch of the vertebral artery on each side.
name: Anterior inferior cerebellar artery
label: b
answer: no
explanation: The image shows a prosection of the cerebellum from a basal view, with the cerebellar hemispheres on each side of the image and the brainstem at the top of the image. The superior cerebellar artery supplies the superior aspects of the cerebellar hemispheres, particularly the anterior lobe. It is a branch of the basilar artery. However, the blue arrow indicates the posterior lobe, the most extensive lobe of the cerebellum, located inferior to the horizontal fissure. Its vascular supply is provided by the posterior inferior cerebellar artery, a branch of the vertebral artery on each side.
name: Superior cerebellar artery
label: c
answer: no
explanation: The image shows a prosection of the cerebellum from a basal view, with the cerebellar hemispheres on each side of the image and the brainstem at the top of the image. The basilar artery is the largest vessel of the posterior circulation of the brain and some of its branches supply the cerebellum – the superior and the deeper aspects of the cerebellar hemispheres. However, the blue arrow indicates the posterior lobe, the most extensive lobe of the cerebellum, located inferior to the horizontal fissure. Its vascular supply is provided by the posterior inferior cerebellar artery, a branch of the vertebral artery on each side.
name: Basilar artery
label: d
answer: no
explanation: The image shows a prosection of the cerebellum from a basal view, with the cerebellar hemispheres on each side of the image and the brainstem at the top of the image. The posterior cerebral artery is a branch of the basilar artery supplying the occipital, the medial parietal and medial temporal lobes of the brain, but not the cerebellum. However, the blue arrow indicates the posterior lobe, the most extensive lobe of the cerebellum, located inferior to the horizontal fissure. Its vascular supply is provided by the posterior inferior cerebellar artery, a branch of the vertebral artery on each side.
name: Posterior cerebral artery
label: e
answer: no

Correct answer: a
