In the photos: A transverse section of the myelinated axon, a long process of a nerve cell. The axon body itself (soma), the surrounding layers of the lipid (fat-like) substance myelin, and the Schwann cell are visible.
Continuation of the topic of the note “Bite very hot… Schwann cells, friends?”
In the mentioned note, I assert and try to argue my claims that Schwann cells are not friends of nerve cells, in particular the axon, but parasites living on the axon and sucking nutrients from it.
The last thought that came to mind six months ago:
And isn’t the mielin “footcloth winding” an axon-soldier way to protect yourself from the Schwann parasite? To distance him from his own body. And slip him layers of fat (let him “fatten”!) but does the axon itself not suck?
After all, in the case of cutting off the axon from the mother cell-neuron, the Schwannovskie immediately begin to devour the separated piece and multiply in its “delta”.
So, perhaps, the axon in the form of protection slips the mielin formed by it: “Here, choke!”
This is just a hypothesis – a continuation of the previous one.
As usual with me, I blurt something out first, and only then I start thinking, well, what did I want to say anyway?
About myelin as a means of protecting the axon from the Schwann cell parasite.
As already stated ten years or more ago, nerve impulses passing through a neuron and its processes are nothing more than the liberation of a cell from “waste products”, that is, in children’s language, writing and pooping neurons.
This means that all our beautiful thinking is described and dusted! Unpleasant, but self-critical. And for most, nothing else is required …
But, returning to axons, it is known that along myelinated thick fibers, nerve impulses propagate at the highest speed – about one hundred meters per second, whereas along non-myelinated (limp) “B” and thin fibers of type “C” they move slowly, at a speed of only a few meters per second.
So, the question is:
From the standpoint of “toilet”, how to combine two seemingly unrelated phenomena.
Protection of the axon by myelin from parasites. (Esprit’s hypothesis)
The fastest transmission of a nerve impulse through SUCH fibers. (An experimental fact.)
Based on the “toilet” hypothesis, I came up with the following explanation.
Non-ethylene fibers “secrete waste products” CONTINUOUSLY throughout the entire length of their fiber!
The one that has nowhere to HURRY!
In myelinated fiber, this is difficult! The areas covered with mielin are locked for “natural needs”!
Therefore, it is necessary to write and poop often and quickly in small portions through the interceptions of Ranvier!
So the impulse runs in leaps from interception to interception, where there are few “holes” for release (the area of contact with the environment is very small) and therefore we must hurry to the next one.
Imagine a person who “needs”, but the toilets open for five seconds! He will have to run along the chain from toilet to toilet in order to “relieve his soul”!
Here is the solution to the rapid propagation of a nerve impulse through a myelinated fiber!
If I’m wrong, let my senior fellow cytologists correct me.
