Ultrastructure of free-ending nerve fibres in oesophageal epithelium.
For the first time, at the ultrastructural level, the existence of free-ending, intraepithelial nerve fibres has been demonstrated in the oesophagus wall of adult cats and monkeys. Their form, the way they penetrate the epithelium, their location within the epithelium and their relationships with neighbouring cells have been established. A sensory function is suggested for this type of ending.
