The motor homunculus is a part of the brain that controls voluntary movements and is organized in a way that different body parts have corresponding areas in the homunculus. The larger the body part, the larger the corresponding area in the homunculus. The elephant's trunk is a large and dexterous body part that is extensively used for manipulating the environment, and therefore, it is expected to have a larger representation in the motor homunculus compared to other body parts.
