Final answer:
The main functions of the spinal cord are motor control and coordination, and sensory input and perception.
Step-by-step explanation:
The main functions of the spinal cord are motor control and coordination, and sensory input and perception. The spinal cord carries information between the brain and the rest of the body. It receives sensory information from the body and transmits it to the brain for processing. It also sends motor signals from the brain to the muscles and organs, allowing for voluntary movement and coordination.
