Endoneurium vs. Neurilemma — What's the Difference?

The endoneurium (also called endoneurial channel, endoneurial sheath, endoneurial tube, or Henle's sheath) is a layer of delicate connective tissue around the myelin sheath of each myelinated nerve fiber in the peripheral nervous system. Its component cells are called endoneurial cells.

Neurilemma (also known as neurolemma, sheath of Schwann, or Schwann's sheath) is the outermost nucleated cytoplasmic layer of Schwann cells (also called neurilemmocytes) that surrounds the axon of the neuron. It forms the outermost layer of the nerve fiber in the peripheral nervous system.The neurilemma is underlain by the myelin sheath (also known as the medullary sheath).

(anatomy) A layer of delicate connective tissue enclosing the myelin sheath of a spinal cord nerve fiber.
