The epineurium is less visible in this image due to the higher magnification but is effectively around the upper-right of the image. Several blood vessels can be seen within the connective tissue around the bundles (seen as small holes within the connective tissue). As was discussed in the image above, the epineurium is often surrounded by adipose tissue. Due to the type of stain used for this image, several adipocytes can be seen to the right of the image. Each nerve bundle is surrounded by the perineurium and this can be clearly seen surrounding each.

Given the lipid stain, it is possible to distinguish the myelinated nerves from the unmyelinated nerves within each bundle. Therefore a large proportion of the nerves are myelinated within each bundle. These myleinated nerves appear at this magnification with a charactristic ''donut'' shape which represents the axon in the centre (which contains no lipid) and the surrounding Scwann cell (containing lipid).
