Abstract
Electron microscopic study of the neurofibrillar body contained in the ganglion cells of nervus terminalis of the tench (Tinca tinca L.), showed a regular association between microtubules and neurofilaments. Tubules of 255 A mean diameter are surrounded by 9 filaments and are resolved by the use of Markham's rotation method in 9 subunits, in cross section. Tubules of 280 A mean diameter, surrounded by 10 filaments, can be resolved in 10 subunits, in cross section. The one-to-one correspondence between tubular subunits and accompanying filaments has been discussed with regard to the possible mechanochemical coupling occurring between microtubules and microfilaments in nerve cells.
