What is "spinal cord"?

The spinal cord is a long, thin, tubular bundle of nerves that runs from the base of the brain to the lower back. It is part of the central nervous system and serves as the main pathway for transmitting signals between the brain and the rest of the body. The spinal cord is protected by the vertebral column and is composed of grey and white matter. Grey matter contains cell bodies and dendrites of neurons, while white matter contains myelinated axons that transmit signals up and down the spinal cord. The spinal cord is responsible for many important functions, including reflex actions, sensory processing, and motor control. Damage to the spinal cord can result in paralysis, loss of sensation, and other serious health problems.

Examples

1. The interneurons in the spinal cord help to relay signals from sensory neurons to motor neurons, allowing for coordinated movements.

2. Multipolar neurons are the most common type of neuron found in the brain and spinal cord.

3. 1 of 300 receives spinal cord injury in their life time.

4. Roughly 300,000 people in the United States have suffered spinal cord injuries, life-changing events with far reaching-effects.
