because it is in continuity with internal carotid artry, usually embolus lodges there.
Left Ventricle to Left side of brain via common carotid Left Ventricle Aortic (semi-lunar) valve Ascending aorta Aortic arch Left common carotid artery Left carotid sinus Left internal carotid artery Left anterior cerebral artery
Oxygenated (O2) blood leaves the heart from the left ventricle entering the ascending aorta where the right and left coronary arteries branch off. The ascending aorta then becomes the Aortic Arch which has three branches: Brachiocephalic trunk, Left Common Carotid, and Left Subclavian. The Brachiocephalic trunk bifurcates into Right Common Carotid and Right Subclavian. The Right and Left Common Carotid bifurcate at C4 (Thyroid Cartilage level) forming the Internal Carotid and External Carotid. The Vertebral Arteries branch of the Right and Left Subclavian, running up the transverse foramina from C6 up to C1 where the Posterior Inferior Cerebellar Artery branches off, as well as the Anterior Spinal Artery. The Vertebral Artery merges to form the Basilar Artery where the Anterior Inferior Cerebellar Artery branches off, as well as the Pontine Arteries and the Superior Cerebellar Artery branches off inferior to the formation of the Right and Left Posterior Cerebral Artery (PCA). The PCA is the beginning of the Circle of Willis where the Posterior Communicating Arteries branch of the PCA connecting to the Internal Carotid Arteries with the Opthalmic Arteries branching off superiorly. The Internal Carotid Arteries become the Middle Cerebral Arteries (MCA) with the Anterior Choroidal Artery branching off inferiorly to the Anterior Cerebral Arteries (ACA) with the Anterior Communicating Artery connecting the two ACA together supplying the brain with O2 blood. The Internal Jugular Vein drains the brain uniting with the Subclavian Vein to form the Brachiocephalic Vein. The Right and Left Brachiocephalic Vein Unite to form the Superior Vena Cava (SVC) dumping the blood into the Right Atrium of the heart.

subclavian artery , carotid artery , vertebrobasilar artery, vertebral artery and cerebral artery. in these, the vertebral arteries are divided into 3 namely anterior, posterior and middle cerebral arteries and these supplies to brain.

The proximal part of the posterior cerebral artery is narrow and its ipsilateral posterior communicating artery is large, so the internal carotid artery supplies the posterior cerebrum.

Blood goes into the Aorta from the heart. Then enters into Common iliac arteries, external iliac arteries, femoral artery, popliteal artery, and then it goes into the anterior tibial and posterior tibial arteries which supply the foot.
The common path is aortic arch > brachiocephalic artery > internal carotid arteryThe internal carotid artery branches off to provide blood to different regions of the brain e.g. ophthalmic, anterior/middle/posterior cerebral
the common foot pulse locations are as follows, the posterior tibial artery and the dorsalis pedia artery (or pedal artery)
vertebral arteries pass through foramen magnum and reach the inferior of the brain & unite to from the basilar artery. The vertebral artery supplies the posterior of the brain. Basilar atery branches into posterior cerebral artery & cerebellar arteries that supply the cerebellum & pons. Common carotid arteries divide & the internal carotid supplies structures internal to the skull

Posterior means "rear" - Anterior means "front. What the report is saying is that the L5/S1 disk is herniated at the back of the disk (posterior) and is impinging on the front of the spinal cord as a result. This is very common for that particular disk, as well as the L4/5 disk.
