zenuwfascikels
Zenuwfascikels, also known as nerve fascicles, are bundles of nerve fibers within the peripheral nervous system. Each fascicle is a discrete structural unit that contains multiple axons, which are the long projections of nerve cells that transmit electrical impulses. These axons are surrounded by connective tissue called endoneurium. Within the fascicle, the axons are further grouped and supported by perineurium, a layer of specialized connective tissue that encloses the entire fascicle. This perineurial sheath plays a crucial role in protecting the axons and regulating the passage of substances into and out of the fascicle, forming part of the blood-nerve barrier.
The organization of axons into fascicles is important for the efficient transmission of nerve signals and
