Imagine that the size of structures within people's brains grow as skills are developed. If this were true, you can predict that the size of the ________ in a ballerina or gymnast would be larger than normal because of their ability to coordinate bodily movements, control posture, and maintain equilibrium.

Question

Quizplus · Accepted Answer

The cerebellum is responsible for coordinating voluntary movements, controlling posture, and maintaining equilibrium, which are critical skills for a ballerina or gymnast. Therefore, if the size of structures within the brain grows as skills are developed, the cerebellum would likely be larger in individuals with highly developed abilities in these areas.  The cerebellum is attached to the brain stem. Damage to this area interrupts the flow of smooth movement causing movement to appear uncoordinated. The cerebellum is also involved in the ability to learn and perform sequences of body movements.
