The make-up of the sciatic nerve.

Why do we need to floss our nerves? A bit of a funny concept, isn't it? And besides, what are we actually doing in the process? Well... to understand this, we first need to cover a bit of anatomy: Nerves (peripheral nerves) are a series of enclosed, cable-like bundles of neurons (nerve cells), which usually provide a pathway for the transmission of electrochemical messages to and from the brain. Within a nerve, each axon is surrounded by a layer of connective tissue called the endoneurium. The nerve fibres are bundled together into groups called fascicles, and each fascicle is wrapped in a layer of connective tissue called the perineurium. Finally, the entire nerve is wrapped in a layer of connective tissue called the epineurium.

The sciatic nerve runs down the leg.




All of these structures then run collectively through a series of tunnels within the body. These tunnels include those of the spine (i.e the intervertebral foramen, where they can be irritated by disc prolapse, or the growth of new bone from the spine due to degenerative change), through muscles, under ligaments, through fascia etc. The point being, is that a nerve can become irritated anywhere along that pathway, by any number of structures...
