Describe in details the image.

Starts by type of tissue followed by the structures within it and the CT around and in between the structures.

Normal bundles of nerve fibers with blood vessels (artery bundles is surrounded by thin CT (epineurium) and CT between fascicles (perineurium)). The spaces within the individual axons are myelin sheath as it is removed during processing of the tissue. Schwann cells are not clear at this magnification.
