Detailed explanation-1: -EXPLANATION: Neurilemna is also known as neurolemna. It is the sheath of schwann, which is the outermost nucleated cytoplasmic layer of schwann cells. Neurilemna surrounds the axon of the neuron. It forms the outermost layer of the nerve fiber.
Detailed explanation-2: -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.
Detailed explanation-3: -The Schwann cells cover the myelin sheath. A well-developed Schwann cell looks like a sheet of paper where the layers of Myelin sheath can be seen along every coil. The outermost layer of the Schwann cells which presents the nucleated cytoplasm. From this cytoplasm, the Neurilemma is formed.
Detailed explanation-4: -epineurium: The outermost layer of dense, irregular connective tissue surrounding a peripheral nerve.
