摘要: Abstract Localization of acetylcholinesterase positive neurons and substance P enkephalin fibers were studied by histochemistry immunohistochemistry in the intermediate sympathetic zone spinal cords 39 human embryos/fetuses from gestation ages five to 40 weeks. Acetylcholinesterase observed nucleus intermediolateralis pars principalis as early fifth week gestation. By ninth 13th weeks gestation, also seen nuclei intermedialis funicularis, intercalatus spinalis paraependymalis. Increase amount these was demonstrated till term. Substance initially eighth intermediolaterlis then detected funicularis well 14th 26th all major par principalis, paraependymalis has fibers. Initial demonstration appeared be at an earlier stage than that our
