Where Are Unmyelinated Nerve Fibers Surrounded By Schwann Cells . They represent the majority of peripheral sensory and autonomic fibers. The axon, its sheath of schwann cells and the surrounding basal lamina form the impulse conducting structures, the nerve fibres, classified in myelinated.

Asked sep 5, 2021 in psychology by valentin. In the peripheral nervous system, nerve cell processes — both axons (neurites) and dendritic axons of sensory neurons — are surrounded by specialised glial cells, the cells of schwann. The plasma membrane spirals around the axon arranging the membranes in concentric layers.

Nerve fibers that are larger in diameter and heavily myelinated (aβ fibers) will depolarize before smaller, unmyelinated nerve fibers (c fibers). In the pns and cns d. The axons present neurofilaments, microtubules and mitochondria (*). The axons of the unmyelinated nerve fibers are small in diameter and usually several are surrounded by a single myelin sheath.
