The information included on the page below is specifically to provide an insight into the histologic appearance of nerves within the PNS. Therefore knowledge of the terminology related to the anatomy and physiology of nerves is assumed and the [[PNS_Structure_-_Anatomy_%26_Physiology|PNS anatomy and physiology]] page should be reviewed to improve the understanding of the information provided below.

This image shows a cross-sectional histology of a myelinated nerve fibre. The section clearly shows numerous bundles of nerve fibres which are slightly out of focus, but appear as the globular contents of the nerve.

The nerve as a whole is surrounded by a dense layer of connective tissue; the epineurium. This layer often contains visible blood vessels and it is likely that there are two such vessels found to the left and upper-left of the nerve. Fat cells (adipose tissue) are also found around the epineurium, although none are clearly visible in this image.
