    Notes: Summary The connective tissue associated with the myenteric plexus of the human oesophagus was studied by light and electron microscopy. Collagen fibres were identified by picrosirius staining with polarization microscopy and from their fine structural morphology. A capsule of connective tissue invests the ganglia while septa of connective tissue separate groups of ganglion neurons, surrounding each individual ganglion neuron and each nerve bundle. Collagen fibrils surround the ganglia, each ganglion neuron and each nerve bundle. The fibrils are disposed in various orientatons forming networks. Elastic, elaunin and oxytalan fibres were identified by their staining characteristics and fine structural morphology. The bulk of the ganglion sheath consists of coarse elastic fibres and elaunin fibres. Elaunin and oxytalan fibres form the intraganglionic network. Oxytalan, elaunin and elastic fibres appear to be located in areas related to different stresses and deformation to which the ganglia of the myenteric plexus are exposed during the contraction of the esophageal wall. The ganglia of the myenteric plexus of the human oesophagus show structural organisation of the connective tissue component similar to that seen in sympathetic and parasympathetic ganglia.

    Notes: The myenteric plexus of the upper 12 cm of the human esophagus was studied quantitatively in five necropsy esophagi using whole-mount preparations in which the neurons were stained by a modified Giemsa method. The numerical densities of ganglia and neurons that first appear just below the caudal edge of the cricopharyngeus muscle increase progressively along the oral aboral axis of the esophagus. In the proximal third of the upper esophagus, the plexus contains 10-34 ganglia/cm and 223-1,306 neurons/cm2. The ganglia in this segment are relatively small, containing 17-55 neurons. In the middle third there are 7-35 ganglia/cm2 and 298-1,991 neurons/cm2. The ganglia contain 30-64 neurons. In the distal third of the upper esophagus, the plexus contains 11-46 ganglia/cm2 and 468-1,955 neurons/cm2. The ganglia contain 33-65 neurons. The total number of neurons in this upper part of the esophagus was calculated to be approximately 225-250,000. © 1994 Wiley-Liss, Inc.
