Formation of synapses on the growth cones in human embryonic inferior ganglion of the vagus.
Ultrastructural study was performed on inferior ganglia of the vagus in human embryos aged 7and 8 weeks (developmental stages 18 to 23, 44 to 56 days). The growth cones are observed between the bundles of axons of the inferior ganglia of the vagus. Many primitive synapses (protosynapses) between dendritic and axonal growth cones are observed.
