Options:
explanation: The image shows an anatomical model displaying a mid-sagittal view of the brain, with the nose and frontal lobe to the left of the image and the occipital lobe and the cerebellum to the right of the image. The internal carotid artery is a branch of the common carotid artery which travels into the skull to provide the terminal branches forming the anterior circulation of the brain (in the circle of Willis). However, the blue arrow points to the anterior cerebral artery, which is a terminal branch of the internal carotid artery supplying the medial aspect of the corresponding frontal and parietal lobes.
name: Internal carotid artery
label: d
answer: no
explanation: The image shows an anatomical model displaying a mid-sagittal view of the brain, with the nose and frontal lobe to the left of the image and the occipital lobe and the cerebellum to the right of the image. The blue arrow points to the anterior cerebral artery, which is a terminal branch of the internal carotid artery supplying the medial aspect of the corresponding frontal and parietal lobes.
name: Anterior cerebral artery
label: a
answer: yes
explanation: The image shows an anatomical model displaying a mid-sagittal view of the brain, with the nose and frontal lobe to the left of the image and the occipital lobe and the cerebellum to the right of the image. The posterior cerebral artery is a terminal branch of the basilar artery supplying the occipital lobe of the brain. It can be identified towards the posterior aspect of the brain in the image. However, the blue arrow points to the anterior cerebral artery, which is a terminal branch of the internal carotid artery supplying the medial aspect of the corresponding frontal and parietal lobes.
name: Posterior cerebral artery
label: c
answer: no
explanation: The image shows an anatomical model displaying a mid-sagittal view of the brain, with the nose and frontal lobe to the left of the image and the occipital lobe and the cerebellum to the right of the image. The vertebral artery is a branch of the subclavian artery, ascending through the transverse processes of the cervical vertebrae to the skull cavity where it anastomoses with the vertebral artery on the contralateral side to form the basilar artery and provide supply for the posterior circulation of the brain (in the circle of Willis). However, the blue arrow points to the anterior cerebral artery, which is a terminal branch of the internal carotid artery supplying the medial aspect of the corresponding frontal and parietal lobes.
name: Vertebral artery
label: e
answer: no
explanation: The image shows an anatomical model displaying a mid-sagittal view of the brain, with the nose and frontal lobe to the left of the image and the occipital lobe and the cerebellum to the right of the image. The middle cerebral artery is a terminal branch of the internal carotid artery supplying the lateral aspect of the frontal, temporal and parietal lobes of the brain. It is not visible in this image because this shows a medial view of the brain, not a lateral one. However, the blue arrow points to the anterior cerebral artery, which is a terminal branch of the internal carotid artery supplying the medial aspect of the corresponding frontal and parietal lobes.
name: Middle cerebral artery
label: b
answer: no

Correct answer: a
