The drawing likely represents a motor homunculus, which illustrates the proportion of the motor cortex dedicated to controlling various parts of the body. The areas for the fingers, thumb, and speech muscles are disproportionately large due to the fine motor control and complex movements they require.  The greater brain area coincides with the importance of different body parts in terms of manipulating objects, using tools, eating, and talking.
