How many vertebrae are there in spinal cord?
The average person is born with 33 individual bones (the vertebrae) that interact and connect with each other through flexible joints called facets. By the time a person becomes an adult most have only 24 vertebrae because some vertebrae at the bottom end of the spine fuse together during normal growth and development.

What are the three main functions of the spinal cord?
What does the spinal cord do?
- Motor Functions - directs your body's voluntary muscle movements.
- Sensory Functions – monitors sensation of touch, pressure, temperature and pain.
- Autonomic Functions – regulates digestion, urination, body temperature, heart rate, and dilation/contraction of blood vessels (blood pressure).
What happens if spinal cord is damaged?
When the spinal cord is damaged, the message from the brain cannot get through. The spinal nerves below the level of injury get signals, but they are not able to go up the spinal tracts to the brain. Reflex movements can happen, but these are not movements that can be controlled.
What organ is anterior to the spinal cord?
The esophagus is (anterior or posterior] to the vertebral column. 9. The brain is (superior or inferior] to the spinal cord.
How many spinal cords are in the human body?
