Collagen fibers in ganglia of the myenteric plexus

ABSTRACT

The connective tissue of the myenteric plexus of the human esophagus was studied by light and electron microscope. Collagen fibers were identified by Picrosirius staining with polarisation microscopy and from their fine structural morphology. A capsule of connective tissue invests the ganglia while septa of connective tissue separate groups of ganglion cells, surrounding each ganglion cell and each nerve fiber. Collagen fibrils surround the ganglia each ganglion cell and each nerve fiber. The fibrils are disposed in various orientations forming networks
