Q: Hi I have a question for you is there a science for the human body nerves, feeling and ect.

A: Depending on how you mean, there are two branches of science here. I think more specifically, you are asking about neuroscience. Neuroscience is concerned with how the brain functions, how it manifests consciousness, and how it interacts with the rest of the body. However, if you want to get into specifically how we think, feel, and why we do those things, psychology is your field. There are also neuropsychologists, people who exist in the middle of that Venn diagram. If you have specific questions about this topic, it just so happens I am near my personal library which contains many books on the topic!
