Some neurons have a fatty layer covering called MYELIN SHEATH around their axon. This layer is not continuous and the gaps are called NODES OF RANVIER.
Because the myelin sheath is made up of insulating fatty substances, the nodes of ranvier allow the fast transmission of electrical impulses along the axon.
I have no idea what you are talking 'bout.
During the course of initiating the scientific method, the hypothesis is considered the first major step. Before that would be identifying a subject and observing a particular issue, animal, etc.
