Unmyelinated nerve fibre analysis of the human lesser splanchnic nerve.
The aim of the present study is to analyse unmyelinated nerve fibres of the human lesser splanchnic nerve in relation to the ageing process. With the help of an image-analyser, we examined 30 human lesser splanchnic nerves. The analysis was conducted with the use of a new staining method that makes it possible to discriminate various structures of the nervous tissue. Our report provides for the first time information on the ageing process of the human lesser splanchnic nerve fibres. The results indicate that a decrease in transverse area and perimeter of unmyelinated axons is one of the important changes occurring in the human lesser splanchnic nerve during the ageing process.
