Nerve Structure (Anatomy)

  • image descriptionNerves are the organs that make up the peripheral nervous system (PNS). They serve as information pipelines that allow the brain and spinal cord to communicate with other tissues and organs.

  • Inside the nerves, groups of image descriptionneurons (nerve cells) are organized into bundles called image descriptionfascicles (fasciculi).

  • This layer appears concentrically laminated and is composed of flattened cells,¬†basement membrane, and collagen fibers.
  • Inside the fasicles, neurons and blood vessels are held in place by a loose connective tissue referrred to as image descriptionendoneurium.
