Corticospinal Tracts: How the Brain Controls Movement

Answer: The corticospinal tracts

Explanation: The primary motor area, also known as the primary motor cortex or M1, is located in the frontal lobe of the brain. It is responsible for sending signals to the skeletal muscles to control voluntary movements. The corticospinal tracts are a group of nerve fibers that connect the primary motor area to the spinal cord. These fibers carry signals from the brain to the muscles, allowing us to control our movements.
