Do you know what the vagus nerve is? This is the nerve behind where we usually feel for pulse and this is the longest nerve in our body.

It’s also one of the 12 cranial nerves and it goes from the brainstem all the way to the abdomen and through several organs, including the oesophagus, lungs, and heart.

Also known as the cranial nerve X, it’s a part of our involuntary nervous system that directs all of our unconscious body actions such as stable heart rate and proper digestive tract function.
