The Telencephalon山东大学医学院解剖教研室 李振华

External feature

The telencephalon consists of right and left cerebral hemisphere, partially separated by cerebral longitudinal fissure. The cerebral transverse fissure intervenes between the hemispheres and the cerebellum Each hemisphere has three surfaces: superolateral, medial and inferior

Three principal sulci
