Abstract :

Supero Lateral Surface of cereal cortex is supplied by the M4 segment of middle cereal artery. Segmental approach is to describe the middle cereal artery are M1, M2, M3, M4. Blood supply to functional lobes is by M4. It passes all the convex surface of cereal hemisphere. Aside from the frontal pole and posterior rim using functional approach to Anatomy of Middle cereal artery arises as a single trunk of 14–16 mm in length and diameter of 3–6 mm and majority it divides and supplied by superior and inferior division. More than one functional areas are supplied by the anch of middle cereal artery. In the middle cereal artery divides into three division as superior, middle and inferior . One artery is more connections are noted in anch of middle cereal artery. Orbito frontal anch arises from the stem of M1 and supplies ocas. Motor speech area and frontal eye field. This occurs in three divisions of middle cereal artery. M1 segment is 30 mm. Lumen size is 6 mm. In the superior division free communication are noted in the 3 anches of middle cereal artery . In three division the angle of supply is also varying as superior is acute angle middle is as right angle . Inferior is acute.
