The supratrochlear artery (or frontal artery) is one of the terminal branches of the ophthalmic artery. It arises within the orbit. [1] [2] It exits the orbit alongside the supratrochlear nerve. It contributes arterial supply to the skin, muscles and pericranium of the forehead. [3]
Middle cerebral artery (MCA), which supplies blood to the majority of the lateral portion of the brain, including the temporal and lateral-parietal lobes. [ 2 ] [ 3 ] It is the largest of the cerebral arteries and is often affected in strokes [ 4 ]
The anterior cerebral artery (ACA) is one of a pair of cerebral arteries that supplies oxygenated blood to most midline portions of the frontal lobes and superior medial parietal lobes of the brain. The two anterior cerebral arteries arise from the internal carotid artery and are part of the circle of Willis .
The ophthalmic artery (OA) is an artery of the head. It is the first branch of the internal carotid artery distal to the carotid sinus. Branches of the ophthalmic artery supply all the structures in the orbit around the eye, as well as some structures in the nose, face, and meninges. Occlusion of the ophthalmic artery or its branches can ...
Areas supplied by the middle cerebral artery include: The bulk of the lateral surface of the hemisphere; except for the superior inch of the frontal and parietal lobe (anterior cerebral artery), and the inferior part of the temporal lobe. Superior division supplies lateroinferior frontal lobe (location of Broca's area i.e. language expression)
The orbitofrontal artery is one of the branches of the anterior cerebral artery, that supplies blood to the cerebrum. [1] The orbitofrontal artery is usually the first cortical branch of the A2 segment , arising from the subcallosal segment to supply the inferior and inferomedial surfaces of the frontal lobe including the gyri recti.

Aneurysms of the anterior communicating artery are the most common circle of Willis aneurysm [4] and can cause visual field defects such as bitemporal heteronymous hemianopsia (due to compression of the optic chiasm), [5] psychopathology and frontal lobe pathology.
