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 anterior cerebral artery supplies a part of the frontal lobe, specifically its medial surface and the upper border. It also supplies the front four–fifths of the corpus callosum, and provides blood to deep structures such as the anterior limb of the internal capsule, part of the caudate nucleus, and the anterior part of the globus ...
The caudate lobe is a separate structure which receives blood flow from both the right- and left-sided vascular branches. [5] [6] The Caudate lobe includes: (1) the Spiegel lobe; (2) the paracaval portion; and (3) the caudate process portion. The Spiegel lobe has its portal venous and biliary branches ramified mainly from the left-side tract.
Cerebral blood flow (CBF) is the blood supply to the brain in a given period of time. [8] In an adult, CBF is typically 750 millilitres per minute or 15.8 ± 5.7% of the cardiac output. [9] This equates to an average perfusion of 50 to 54 millilitres of blood per 100 grams of brain tissue per minute. [10] [11] [12]
The caudate lobe has a complex blood supply system. It derives its arterial supply from the caudate arteries, which arise from the right, left, and middle hepatic arteries that are connected to each other. [7] Besides, the caudate lobe also derives its supply from the right and left branches of the portal vein.
The recurrent artery of Heubner, Heubner's artery or distal medial striate artery [1] is a branch of the anterior cerebral artery.It supplies the head of the caudate nucleus and adjacent part of the anterior limb of internal capsule, olfactory regions, [2] and parts of the putamen and septal nuclei.
The anterior limb of the internal capsule (or crus anterius) is situated in front of the genu, between the head of the caudate nucleus and the lentiform nucleus. [4] It contains: Thalamocortical fibers passing from the lateral thalamic nuclei to the frontal lobe [4] Corticothalamic fibres passing from the frontal lobe to the lateral thalamic ...
Angiogram of the arterial supply. The cerebral arteries describe three main pairs of arteries and their branches, which perfuse the cerebrum of the brain. The three main arteries are the: Anterior cerebral artery (ACA), which supplies blood to the medial portion of the brain, including the superior parts of the frontal and anterior parietal ...
