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 lobes [1]
The leptomeningeal collateral circulation (also known as leptomeningeal anastomoses or pial collaterals) is a network of small blood vessels in the brain that connects branches of the middle, anterior and posterior cerebral arteries (MCA, ACA, and PCA), [1] with variation in its precise anatomy between individuals. [2]
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.
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 middle cerebral artery (MCA) is one of the three major paired cerebral arteries that supply blood to the cerebrum. The MCA arises from the internal carotid artery and continues into the lateral sulcus where it then branches and projects to many parts of the lateral cerebral cortex .
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 anterior choroidal artery typically originates from the internal carotid artery.It may (rarely) instead arise from the middle cerebral artery. [1]It originates from the distal internal carotid artery (ICA) 5 mm distal to the origin of the posterior communicating artery and just proximal to the terminal bifurcation of the ICA.
The pulp is a soft tissue area containing the nerve and blood vessels to nourish and protect the tooth, located within the pulp cavity. A tooth sits in a specialized socket called the alveolus. The tooth is held in location by a periodontal ligament , with the assistance of cementum .
