Cytoplasm of schwann cell
WebSchwann cells are found in the dorsal root ganglia where they associate with the neuronal cell bodies of sensory neurons. (b) Non-myelin-forming ... are in continuity with the Schwann cell cytoplasm of the outer and inner mesaxonal regions (Fannon et al. 1995; Ghabriel and Allt 1981; Arroyo and Scherer 2000). These components of the myelin-forming Webneuron Schwann cells or neurolemmocytes: wrap around portion of only one axon to form myelin sheath. Wrap around many times. During development, as cells grow around axon, cytoplasm is squeezed out and multiple layers of cell membrane wrap the axon. Cell membrane primarily phospholipid.

WebDouble immunofluorescence analysis revealed that these inclusions were co-localized with S-100 protein β, suggesting that these inclusions were localized in the cytoplasm of Schwann cells. The peripheral nervous system including Schwann cells may be involved in TDP-43 pathology in ALS. WebImagine that a Schwann cell is a pillow with the pillowcase representing Schwann cell membrane and the pillow's stuffing representing Schwann cell nucleus and cytoplasm. Next imagine a broomstick (representing the axon) lying across one end of the pillow.
WebMyelin incisures (also known as Schmidt-Lanterman clefts, Schmidt-Lanterman incisures, clefts of Schmidt-Lanterman, segments of Lanterman, medullary segments ), are small … WebA decrease in unmyelinated and small myelinated axons appeared earlier than a decrease in large myelinated fibers in diabetic neuropathy. Electron microscopic studies of human diabetic neuropathy demonstrated edematous cell cytoplasm, aggregates of glycogen particles, and hyperplasia of the surrounding basal lamina in Schwann cells.
