Title: Unmyelinated axons I
Description:
(A): Electron miroscopy scheme of the cell of Schwann showing two enclosed axons.
(B): Electron micrograph peripheral unmyelinated nerves, human. The arrows point to enclosed or wrapped axons in the cytoplasm of a Schwann cell.
(C): Electron micrograph, golden hamster. Cross-section through the area of a principal bronchus shows the Schwann cell with numerous included axons, all without an electron-dense myelin sheath. (Arrow) Basal lamina of Schwann cell.
(1) Endoneurium.
(D): Electron microscopy scheme of the beginning of the wrapping of an axon by the Schwann cell.
(E, F): Electron micrographs of unmyelinated nerves, human. Arrows indicate the neurotubules.
The neuro- filaments are much thinner. (F) is detail of (E). Generally, the loose connective tissue between individual nerve fibers is called endoneurium. Perineurium (or perineural epithelium) covers the entire bundle of nerve fibers.
Keywords/Mesh: nervous tissue , peripheral nerve fiber, unmyelinated nerve fiber, Schwann cell, neurotubule, endoneurium, histology, electron microscopy, POJA collection
