On possible effects of the spinor structures in Quantum Physics

The paper discusses the following topics: spinor coverings for the full Lorentz group, intrinsic parity of fermions, Majorana fermions, spinor structure of space models, two types of spacial spinors, parametrization of spinor spaces by curvilinear coordinates, manifestation of spinor space structure in classifying solutions of the quantum-mechanical equations and in the matrix elements for physical quantities.
