Ultrastructural study was conducted on the superior cervical sympathetic ganglia in human foetus aged 23 weeks. It was shown that in investigated foetus the nerve fibres in the ganglion were in different phases of myelination. Also growth cones, which present evidence of still growing fibres, were observed.
