Humans Have More Than Five Senses
Humans have the ability to take in information in many different ways. We know where our bodies are located in space thanks to Proprioception, which allows us to find balance. Kinesthetic receptors allow us to keep track of our body parts, allowing us to detect stretching in our tendons and muscles.
There are also some receptors that allow us to know how much oxygen we’ve got running through our arteries.
