Darkfield light micrograph of a section of intestinal muscle, showing nerve cell bodies (black) and their axons and dendrites (yellow and orange colour) of the myenteric (Auerbach's) plexus. This network of neurons controls local intestinal wall movement. When the wall is stretched, or dilated, by its contents, nerves in the plexus cause the muscles above the dilation to contract and those below it to relax, resulting in a wave-like movement (peristalsis) of the gut contents towards the anus. The nerves are arranged in groups (ganglia), connected by long projections (narrow orange/yellow lines), which deliver signals between the nerves. Silver stain. Magnification x120 when printed at 10cm.
