What are orientations of spin of sub atomic particles.i.e. electron, proton and neutron? What is physical interpretation of spin of these particles?

I know that these are spin half particles having spin 1/2. My professor of Quantum mechanics told me that spin of sub atomic is not like spin of earth. It is just intrinsic property of particles...
