Options:
explanation: The image shows a representation of the basal view of the brain with the arteries in situ. The frontal lobe is at the top of the image, while the cerebellum is at the bottom of the image. The occipital and temporal lobes of the brain are supplied by terminal branches of the posterior cerebral artery, which is a terminal branch of the basilar artery. However, the blue arrow indicates the superior cerebellar artery (SCA) which is a branch of the basilar artery, found immediately inferior to the posterior cerebral arteries. The function of the SCA is to provide arterial supply to the superior surface of the cerebellar lobes.
name: Gives off terminal branches to supply the occipital and temporal lobes of the brain
label: c
answer: no
explanation: The image shows a representation of the basal view of the brain with the arteries in situ. The frontal lobe is at the top of the image, while the cerebellum is at the bottom of the image. The blue arrow indicates the superior cerebellar artery (SCA) which is a branch of the basilar artery, found immediately inferior to its terminal branches – the posterior cerebral arteries. The function of the SCA is to provide arterial supply to the superior surface of the cerebellar lobes.
name: Supplies the superior surface of the cerebellum
label: a
answer: yes
explanation: The image shows a representation of the basal view of the brain with the arteries in situ. The frontal lobe is at the top of the image, while the cerebellum is at the bottom of the image. The inferior surface of the cerebellum is supplied by the posterior inferior cerebellar artery (PICA) which is a branch of the vertebral arteries before they unite to form the basilar artery. However, the blue arrow indicates the superior cerebellar artery (SCA) which is a branch of the basilar artery, found immediately inferior to its terminal branches – the posterior cerebral arteries. The function of the SCA is to provide arterial supply to the superior surface of the cerebellar lobes.
name: Supplies the inferior surface of the cerebellum
label: b
answer: no
explanation: The image shows a representation of the basal view of the brain with the arteries in situ. The frontal lobe is at the top of the image, while the cerebellum is at the bottom of the image. The medial aspect of the frontal lobe of the brain is supplied by the anterior cerebral artery, which is a branch of the internal carotid artery forming part of the anterior circulation of the brain. However, the blue arrow indicates the superior cerebellar artery (SCA) which is a branch of the basilar artery, found immediately inferior to its terminal branches – the posterior cerebral arteries. The function of the SCA is to provide arterial supply to the superior surface of the cerebellar lobes.
name: Supplies the medial aspect of the frontal lobe of the brain
label: e
answer: no
explanation: The image shows a representation of the basal view of the brain with the arteries in situ. The frontal lobe is at the top of the image, while the cerebellum is at the bottom of the image. The flocculus and the anteroinferior surface of the cerebellum are supplied by the anterior inferior cerebellar artery (AICA), which is a branch arising from the proximal part of the basilar artery, immediately superior to the union of the vertebral arteries. However, the blue arrow indicates the superior cerebellar artery (SCA) which is a branch of the basilar artery, found immediately inferior to its terminal branches – the posterior cerebral arteries. The function of the SCA is to provide arterial supply to the superior surface of the cerebellar lobes.
name: Supplies the flocculus and the anteroinferior surface of the cerebellum
label: d
answer: no

Correct answer: a
