Cerebral Vasculature Explained for Medical Students | Circle of Willis & Stroke

For more cadaveric images and question banks, visit https://bootcamp.com/med-school The cerebral vasculature is critical for understanding stroke syndromes. In this video, we explore the Circle of Willis, cortical and cerebellar territories, and angiogram anatomy. Learn how occlusions in the ACA, MCA, or PCA produce distinct motor, sensory, and language deficits, and how cerebellar arteries (SCA, AICA, PICA) contribute to balance and coordination. Clinical case studies illustrate how to localize vascular lesions from patient symptoms. You’ll learn 1. Entry routes: internal carotid via carotid canal; vertebral → basilar via foramen magnum 2. Circle of Willis: ACA, MCA, PCA, ACom, PCom; key branches (ophthalmic, anterior choroidal, lenticulostriates) 3. Territories: ACA → medial frontal/parietal (leg greater than arm) MCA → lateral hemispheres (face/arm, language in dominant hemisphere) PCA → occipital & inferior temporal (visual field cuts) 4. Cerebellar supply: SCA, AICA, PICA basics 5. Clinical integration: localize deficits (eg, left MCA → right face/arm weakness, aphasia); read the “stick-figure” on angiogram to spot occlusions ⏱️ Timestamps 0:00 – Intro & case study (stroke presentation) 1:02 – How blood enters the cranial cavity (internal carotid & vertebral arteries) 1:22 – Internal carotid artery pathway & contribution 1:45 – Vertebral artery pathway → basilar artery 2:08 – Vertebral artery branches: anterior & posterior spinal arteries 3:04 – Posterior inferior cerebellar artery (PICA) 3:23 – Anterior inferior cerebellar artery (AICA) 3:51 – Vertebral arteries join → basilar artery & pontine branches 4:41 – Superior cerebellar artery (SCA) 5:09 – Posterior cerebral artery (PCA) & posterior communicating artery (PCom) 5:37 – Internal carotid branches → middle cerebral artery (MCA) & anterior cerebral artery (ACA) 6:03 – Anterior choroidal & ophthalmic arteries 6:28 – Anterior communicating artery (ACom) & medial striate arteries 7:43 – Circle of Willis overview & collateral flow 8:08 – Angiogram: identifying arteries with “stick figure” method 9:23 – Middle cerebral artery branches on angiogram 10:11 – Posterior communicating & posterior cerebral arteries 10:34 – Identifying vertebral & basilar arteries on angiogram 11:21 – Cortical territories: ACA, MCA, PCA supply 12:49 – Midline view: ACA vs PCA distributions 13:34 – Homunculus blood supply mapping 14:28 – Stroke localization examples (ACA vs MCA occlusion) 14:52 – Cerebellar blood supply: SCA, AICA, PICA 16:05 – Revisiting case study: left MCA occlusion → symptoms explained 17:41 – Angiogram occlusion example: MCA stroke 18:58 – Practice question: cortical territories (ACA vs PCA) 19:48 – Practice question: angiogram vessel identification 21:00 – Summary: arteries, territories, lesion localization This lesson is especially helpful for medical students, or anyone reviewing for anatomy exams.
