How the Body Works: The Left Hemisphere

In this illustration we will see the left hemisphere of the brain from three different views.

Here, the brain is seen in a cross section from the side with the right hemisphere removed.

Here is a frontal elevation of the hemispheres. The solid red patches indicate some of the areas involved with the control and production of language. Language areas on the surface of the left hemisphere are shown here. Broca's area is involved in the motor control of speech, and Wernickes's area in more general language control. Naming and writing are controlled by other areas.
