The cerebellum governs a human's every movement. It governs some unconscious and automatic functions, such as balance and controls and coordinates voluntary body movements. The Brain, Mystery of Matter and Mind says: The paired lobes assumes the silhouette of a moth. Between thewings? curls a grublike section called the vermis, which helps to maintain balance, tone muscles, control posture? (29). An athlete's movement is the result of complex nerve impulses from incoming and outgoing fibers. .
Two of your brain's primary neurotransmitters are associated with movement, and acetylcholine is used in neuromuscular transmission. Neurons not only contact other neurons; they also connect with skeletal muscle fiber at a specialized stucture called the neuromuscular junction. Acetycholine - the primary neurotransmitter for memory - is the one used to communicate with muscles. .
A body is a computer that needs to be programmed. As the brain analyzes every movement, it also automatically stores it in a neuron. This neuron will .
transmit this information automatically to the muscle needed for such movement in the future. An athlete spends numerous hours in practice to gain experience and the brain will adjust its stored memory as improvement in noted. For beginners, most responses have to be thought out consciously. With experience, the motion becomes automatic because the brain has calculated the correct response before. The book titledThe Brain and the Nervous System? states: The cerebellum corrects movement in tow ways. First, it adjusts the activity of motor nerve cells in the .
spinal cord, which directly affect the muscles. Second, it continually updates the central motor program? (52).
We can say that brainless people are spineless people. We cannot speak of an athlete without the brain. On page 53, in the bookThe brain and Nervous System? says,the nerve cells in the brain stem receive input form the cerebellum and the motor cortex.
