WebbIt contributes to the tensile strength of the nerve and to the sliding, but it does not provide a barrier function. 10,11 The perineurium surrounds the axon filaments with a dense connective ... WebbIt is formed when Schwann cells (blue) wrap around the fibre, depositing layers of myelin between each coil. Unmyelinated nerve fibres are also present. An outer sheath or perineurium surrounds the connective tissue endoneurium that in turn surrounds the nerve fibres and Schwann cells. Magnification: x1500, when printed 10 centimetres wide.

WebbThe perineurium surrounds each individual nerve fiber within the dorsal root ganglion. It provides structural support for the neuron and prevents it from being damaged by external forces. The perineurium is composed of a single layer of epithelial cells that enclose the space between the epineurium and the endoneurial fluid. WebbThe perineurium:-surrounds axons and Schwann cells-contains sensory neurons only-encloses all the fascicles to form a nerve-binds groups of fibers into bundles WebbThe perineurium ______. A. encloses all the fascicles to form a nerve. B. surrounds axons and Schwann cells. C. binds groups of fibers into bundles. D. contains sensory neurons … how to shave your own head
