In my previous blog, I explained in general how the various nerves systems work and what the impact of a hit on a nerve is.

The spinal cord
As you can see, the spinal cord is fragmented in 4 parts.
- C = Cervical
- Th = Thoracic
- L = Lumbar
- S = Sacral
- C5 to Th1: this is where the signals pass from the brain to the arms (and the other way around)
- Th1 – Th4: are connected to the heart and lungs
- Th5 – Th12: are connected to the stomach, liver, gall bladder, pancreas, adrenal gland, small intestine and large intestine.
- L1-L3: are connected to the Large intestine, kidney and bladder
- L1 to S3: this is where the signals pass from the brain to the legs (and the other way around)
In the last part, next time I will write about the brainstem.
