Does the spinal cord send messeges to brain?

Yes, the spinal cord sends messages to the brain.

The spinal cord is a long, cylindrical bundle of nervous tissue that runs from the brain down the back. It acts as a communication pathway between the brain and the rest of the body. The spinal cord carries sensory information from the body to the brain and motor information from the brain to the muscles.

Sensory information is carried by sensory neurons, which are specialized nerve cells that detect stimuli from the environment. Motor information is carried by motor neurons, which are specialized nerve cells that control muscle movement.

The spinal cord is also involved in reflexes, which are automatic responses to stimuli. When a reflex occurs, a sensory neuron sends a message to the spinal cord, which then sends a message to a motor neuron, which causes a muscle to contract.
