the neurilemma of axons in the pns is formed by
Neurilemma Neurilemma (also known as neurolemma, sheath of Schwann, or Schwann's sheath)[1] 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.[2]
Nervous tissue The function of nervous tissue is to form the communication network of the nervous system by conducting electric signals across tissue.[12] In the CNS, grey matter, which contains the synapses, is important for information processing. White matter, containing myelinated axons, connects and facilitates nerve impulse between grey matter areas in the CNS.[13] In the PNS, the ganglion tissue, containing the cell bodies and dendrites, contain relay points for nerve tissue impulses. The nerve tissue, containing myelinated axons bundles, carry action potential/nerve impulses.[10]
