An anatomical term meaning a sharp bend, applied to several structures including the bend of the corpus callosum and the femur.
Structure
The genu of the corpus callosum is the rounded front portion that curves downward to connect the frontal lobes. The femoral genu refers to the knee end of the femur.
Function
Each genu carries its own specific traffic. Fibers crossing through the genu of the corpus callosum link the two frontal lobes, allowing coordination of language, planning, and emotion.
Clinical note
Stroke in the genu of the corpus callosum can produce subtle disconnection symptoms between the frontal lobes.
