Brain, Nervous Systems Work Together to Help You Move
The main player in the story about the brain and movement is the cerebrum -- the largest part of the brain and the part that controls movement, thinking and memory.
Linking the brain's messages about movement to the muscles in your body is the central and peripheral nervous systems. It uses the spinal cord and nerves as a highway to connect messages to muscles and directs them to make movement happen.
"The foundation for the central nervous system is completed during the fourth week of gestation with closure of the neural tube," said Dr. Tord Alden, neurosurgeon at Children's Memorial Hospital in Chicago and assistant professor at Northwestern University.
Other parts of the brain also contribute to the process of movement, Alden said.
"The cerebrum, thalamus, cerebellum, brainstem, spinal cord and nerve roots that direct messages through the peripheral nerves to the muscles are all important players
involved in movement," he said. …
