99-LH2 Peripheral Nerve
Sciatic Nerve Human ls
High magnification view of a longitudinal section through a number of myelinated
nerve axons. The endoneurium (EN) is a thin layer of delicate connective
tissue (blue) that surrounds each nerve fiber. In this tissue, the myelin
(My) wrappings do not stain well as lipids are removed in the tissue processing.
The central axon (Ax) is visible as is a nucleus (NC) of a neurolemmal
cell which invests each myelinated axon in concentric wrappings of cell
membrane. The junction between two adjoining neurolemmal cells presents
a slight gap - Node of Ranvier (NR).
