Peripheral nerve
Peripheral nerves can be found coursing through tissues of the body. Generally, nerves appear well demarcated from surrounding tissue due to the presence of the perineurium. Nerves do not have a lumen and often have a wavy appearance in longitudinal section. These two characteristics distinguish nerves from blood vessels or the ducts of glands. 400x
