Question Answer What are the two main vessels that supply Internal Carotid Artery and Vertebral Artery. blood to the brain? How many segments does the internal Four segments. carotid artery have? Where does the petrosal segment of the In the carotid canal. internal carotid artery lie? What does the petrosal segment of the Caroticotympanic arteries. internal carotid artery give at the end of the carotid canal? What are the branches of the cerebral Ophtalmic artery, Anterior cerebral artery, Middle cerebral artery, Posterior communicating artery, segment of the internal carotid artery? Anterior choroid artery (sometimes). Explain the pathway of vertebral artery? Foramina of the transverse processes (C1 - C6) , pierceThe atlanto-occipital membrane and go through The foramen magnum. Where do both vertebral arteries join and They join on the inferior margin of the pons and form the basilar artery. what do they form? What are the branches of the vertebral Cervical (Muscular, Spinal) and Cranial (posterior inferior cerebellar artery, posterior spinal a., artery? anterior spinal a.). What are the cerebral branches of the Posterior spinal artery, Anterior spinal artery, Posterior inferior cerebellar artery, Basilar artery. vertebral artery? Where does the basilar artery run? In the basilar sulcus on the ventral surface of the pons. What are the branches of the basilar artery? Anterior inferior cerebellar artery, labyrinthine artery, superior cerebellar artery, posterior cerebral artery, pontine artery. What does the cerebral arterial circle (circle The hypothalamus. of Willis) surround? What arteries form the cerebral arterial circle 1. Anterior communicating a. (from internal carotid artery - ICA), 2. Anterior cerebral a. (ICA), 3. (circle of Willis)? Internal carotid a., 4. Posterior communicating a. (ICA), 5. Posterior cerebral a., 6. Basilar a. What is the first segment of the anterior Between the internal carotid and anterior communicating arteries. cerebral artery located between? What does the first segment of the anterior Thalamo-striatal arteries, Short middle artery and Long middle artery (HAUBNER’S artery), which cerebral artery supply? supply Putamen, head of the caudate nucleus, anterior crus of the internal capsule. What are the branches of the second Medial fronto-basilar artery, polar frontal artery, anterior medial frontal artery, intermediate medial segment of the anterior cerebral artery? frontal artery, posterior medial frontal artery, paracentral artery, cingular branch, pericallosal artery, precuneal artery. ---NOTE---: ANY artery with the name : medial frontal is basically branch of anterior cerebral artery What are the three parts of the middle Sphenoid part, Insular part, Cortical part (terminal). cerebral artery? Where does the insular part of the middle Parieto-frontal and temporal operculum. cerebral artery go between? Name some branches of the middle cerebral Middle branches (striato-capsular), Frontal branches, Temporal branches, Parietal branches, Terminal artery. branches. What does the middle cerebral artery supply Thalamus, Corpus striatum, Insula, Cortex (lateral surface and medial of the anterior part of the in the brain? temporal lobe). Where is the first segment of the posterior Between the basilar artery and posterior communicating artery. cerebral artery located? Where does the second segment of the Around the midbrain in the cistern and through the tentorial notch, reaching the medial surface of the posterior cerebral artery pass around? temporal lobe. What are the branches of the posterior Posterior Choroid artery, Thalamo-perforated aa, Geniculo-thalamic aa, temporal, occipital, and Question Answer cerebral artery? occasionally parietal. What are the types of cerebral veins? Superficial veins and deep veins. Where do superficial veins collect blood The cortex of the palium and its neighbors. from? Where do superficial veins empty to? Sinuses of the dura mater. What do the superior cerebral veins drain? The blood of the supero-lateral and medial surface. What do the inferior cerebral veins drain? The blood of the inferior and inferior part of the supero-lateral surface. What is the function of the middle superficial Drains blood of the supero-lateral surface and empties to the cavernous sinus or spheno-parietal cerebral vein? sinus. Where does the Great Cerebral Vein empty? To the proximal part of the straight sinus. What are the tributaries of the Internal Thalamo-striate vein, choroid vein, vein of the vellum pallucidum. Cerebral Vein? What does the anterior cerebral vein drain? The orbital surface of the frontal lobe. What does the middle deep vein drain? The insula and operculum. Name the Tributaries of great cerebral vein ? Internal cerebral vein Basilar vein Where is cerebrospinal fluid secreted by? Choroid plexus. What is the circulation pathway of Lateral ventricle, interventricular foramen, third ventricle, aqueduct, fourth ventricle, medial and lateral cerebrospinal fluid? foramina, subarachnoid space, and absorption in sinuses of the dura matter and veins of the vertebral canal.
