[Development of interneuronal synaptic junctions in neuroblasts of the anterior horn of the spinal cord during early prenatal human ontogenesis (7--9 wks. of pregnancy)].
A method of electron microscopy was applied to the study of the synaptogenesis in the presumptive ventral horns of the spinal cord (C4--Th3) at the early prenatal human ontogeny. The morphological stages of synaptogenesis were traced, and the minimum of the structrual organization of the synapse, correspoding to the beginning of its functional activity, was determined. A hypothesis is put forward on possible mechanisms of synaptogenesis.
