Abstract: | A study was made of the morphological peculiarities of the varicose corpuscles revealed in man and animals at the terminal stages of ontogenesis along the peripheral nerve fibers. The properties of these varicose bodies were compared with the reactive varicose deformities experimentally observed under conditions of disturbed blood supply. Similar features of the two formations compared and the presence of transitional forms permit to regard the former ones as the reactive structures. However, more time and participation of the surrounding tissue is required for their formation. |
