The Motor System

The motor system is responsible for controlling and coordinating movements in the body. It includes the brain, spinal cord, and nerves that send signals to muscles, telling them when and how to move. The brain plans and initiates action, while the spinal cord acts as a communication highway. Nerves extend from the spinal cord to muscles, transmitting electrical signals that cause muscles to contract or relax. This system allows for precise, voluntary movements like walking or writing, as well as involuntary actions like reflexes. Overall, it enables us to interact with and respond to our environment effectively.
