Myelinated and Unmyelinated Neurons? Where Are They?

[jimmydasaint]

From what I understand presently, and this is tenuous knowledge, neurons come in three types: sensory, interneuron (relay neurons in the UK) and motor neurons which are in contact with muscle or glands. Some neurons are covered in a fatty non-conducting substance called myelin which speeds up the electrical impulses carried by neurons. The presence of myelin speeds up the impulses in comparison to neurons that have no myelin. Correct so far?

 

My problem is that I want to be exact about which neurons are myelinated in the body and which are not. Therefore I need more expert help, a reference or two... and where else could I go to except here?
