Part of the extrinsic nerve fibres originate from the vagus nerve and can be found on both intestinal plexuses, the other fibres are processes of the coeliac ganglion and occur in the first place in the vascular tunica adventitia. The intrinsic nerve cells may be classified into three groups on grounds their ultrastructure the number of synapses and processes on their surface.
