Autonomic fibers connecting to viscera
nerve fibers (fascicle) is, in turn, enclosed in a sleeve of looser connective tissue called the perineurium. A small amount of loose connective tissue called endoneurium surrounds individual nerve fibers (figs. 11.24 and 11.25). Blood vessels in the epineurium and perineurium give rise to a network of capillaries in the endoneurium that provides oxygen and nutrients to the neurons.
