Schwann cells or neurolemmocytes (named after German physiologist Theodor Schwann) are the principal glia of the peripheral nervous system (PNS). Glial cells function to support neurons and in the PNS, also include satellite cells, olfactory ensheathing cells, enteric glia and glia that reside at sensory nerve endings, such as the Pacinian corpuscle.
Nervous tissue, also called neural tissue, is the main tissue component of the nervous system.The nervous system regulates and controls body functions and activity. It consists of two parts: the central nervous system (CNS) comprising the brain and spinal cord, and the peripheral nervous system (PNS) comprising the branching peripheral nerves.
The nonmyelinating Schwann cells are a subgroup of the Schwann cells characterized by not forming myelin. [1]The group of nonmyelinating Schwann cells includes the terminal Schwann cells, present at neuromuscular junctions, the Schwann cells of Remak fibers (also called Remak Schwann cells) and the Schwann cells associated to sensory structures, like tactile corpuscles and lamellar corpuscles.
The description of the cells was evident from passages such as: [3] Some, however, appear to remain for a longer period; occasionally, although rarely, a cell-nucleui is here and there seen upon the side of a nerve (the white substance of which is completely developed), lying in the pale border, which surrounds the white substance.
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]
Structure of a typical neuron with Schwann cells in the peripheral nervous system. Neurons are highly specialized for the processing and transmission of cellular signals. Given the diversity of functions performed in different parts of the nervous system, there is a wide variety in their shape, size, and electrochemical properties.
The cells adhere to the surface of the matrix in 2D layers. The supportive scaffolds are easily transplanted into the brain injury site because of the scaffold size. They provide a matrix promoting cell adhesion and aggregation, thus increasing increased healthy cell culture.
These occur when a non-myelinating Schwann cell bundles the axons close together by surrounding them. [4] The Schwann cell keeps them from touching each other by squeezing its cytoplasm between the axons. [4] The condition of Remak bundles varies with age. [4] The number of C fiber axons in each Remak bundle varies with location. [3]
