What is the espinal cord?</h3>
There are two organs involved in the central nervous system that function as control centers,
The spinal cord is a nerve tube placed in a hollow space left between vertebras along the vertebral column. The vertebrae's body protects the spinal cord.
It is made of nerves that take orders from the brain to the rest of the body and send messages from the body to the brain.
Reflexes acts are produced in the medulla, and the brain is not involved.
The nervous cells of the medulla have fibers that extend from the medulla to the body and are connected to sensory receptors.
When receptors receive stimuli, they send information to the nerve fibers, which take it to the brain. From the brain, they send a response.
The answer is spinal cord.
