1. The result show: nematolysosome presents in Purkinje cell.

2. Conclusion NPY immunoreactive neurons are located in cerebellum Purkinje cell layer.

3. The AVN composed of four types cells, P cell, T cell, Purkinje cell and normal cardiac working cell.

4. This neuronal pathway is referred to as the cerebellum to Purkinje cell climbing fiber pathway and it is implicated in the coordination of movements.
