Fig. 1.7.07. Axodendritic contact from the same location as in the previous electron micrograph, fixed with potassium permanganate according to Luft. All cytoskeletal ultrastructure was lost, only membranous structures are left. Axon terminal (T) contains synaptic vesicles and mitochondria, extremely fine tubules of smooth endoplasmic reticulum are apparent on both presynaptic and postsynaptic aspect of the contact (arrows). D - dendritic trunk. Scale = 500 nm. (Rat, thalamic ventrobasal nucleus.) Download the high resolution image.
