The basilar artery (U.K.: / ˈ b æ z. ɪ. l ə /; [1] [2] U.S.: / ˈ b æ s. ə. l ər / [3]) is one of the arteries that supplies the brain with oxygen-rich blood.. The two vertebral arteries and the basilar artery are known as the vertebral basilar system, which supplies blood to the posterior part of the circle of Willis and joins with blood supplied to the anterior part of the circle of ...
The basal ganglia (BG) or basal nuclei are a group of subcortical nuclei found in the brains of vertebrates. In humans and other primates , differences exist, primarily in the division of the globus pallidus into external and internal regions, and in the division of the striatum .
The anterolateral central arteries or lenticulostriate arteries [3] (also anterolateral perforating arteries, anterolateral ganglionic arteries, striate arteries, or lateral striate arteries; latin aa. centrales anterolaterales, [4] or aa. lenticulostriatae [4]) are a group of small arteries mostly arising from (the initial M1 part of) the middle cerebral artery that enter the brain through ...
The caudate nucleus is one of the structures that make up the corpus striatum, which is part of the basal ganglia in the human brain. [1] Although the caudate nucleus has long been associated with motor processes because of its role in Parkinson's disease, [2] [clarification needed] [3] it also plays important roles in nonmotor functions, such as procedural learning, [4] associative learning ...
The superior parts of both the anterior and posterior limbs, and the genu of the internal capsule are supplied by the lenticulostriate arteries, which are branches of the M1 segment of the middle cerebral artery. The inferior half of the anterior limb is supplied via the recurrent artery of Heubner, which is a branch of the anterior cerebral ...
The M1 segment perforates the brain with numerous anterolateral central (lateral lenticulostriate) arteries, which supply the basal ganglia. M2: Extending anteriorly on the insula, this segment is known as the insular segment. It is also known as the Sylvian segment when the opercular segments are included.
The anterior communicating artery connects the two anterior cerebral arteries and could be said to arise from either the left or right side. All arteries involved give off cortical and central branches. The central branches supply the interior of the circle of Willis, more specifically, the Interpeduncular fossa.
For intraparenchymal hemorrhage associated with hypertension, small holes in arteries are thought to cause bleeding in the deep penetrating arteries of the brain, which are smaller and thinner than other arteries. These are the arteries that supply blood to the basal ganglia, the thalamus, the brainstem, and deep portions of the cerebellum ...
