Image analysis of the sympathetic innervation of the myenteric plexus in the small intestine of mammalian species.
1. The arrangement of the sympathetic innervation of the myenteric plexus varies between mammalian species. 2. In larger mammals the density of sympathetic innervation of the myenteric plexus is significantly less than in small (less then 1 kg) species. 3. The number of varicosities on the terminal parts of sympathetic neurons innervating the gut is significantly less in larger mammals.
