Nervous respiratory nerves.. Of the brain cortex of the bridge area and another tangle in the spinal cord works to give the final neurons

Nervous respiratory nerves:
Some of these nerves come from the brain cortex, some from the bridge area and another to the spinal cord to give the final neurons that reach the respiratory muscles to move response commands.
The diaphragmatic nerve that forms the diaphragm works in the second cervical vertebrae, while the intercostal nerve that forms the interstitial intercostal muscle is intertwined in the first thorax. The skeletal muscles are concentrated in the nerves coming from the brain.
