Development of the myelin sheath of the hypogastric nerves in a human foetus aged 23 weeks
Folia Morphol 2004;63(3):289-301.
Abstract
The formation of the myelin sheath of the human hypogastric nerves was studied
by electron microscopy in a foetus of 23 weeks of postovulatory age (220 mm
C-R length). In the investigated foetus the hypogastric nerves were mainly composed
of bundles of unmyelinated fibres. The myelinated fibres were seen to be
at different stages of myelination. Well myelinated fibres had thick compact
laminated myelin. The number of myelin lamellae on a single fibre was 22.
