In the peripheral nervous system, a chemical neurotransmitter carries the nerve impulses from neuron to neuron across a synapse (space between neurons). The neurotransmitters are acetylcholine, norephinephrine, serotonin, and others. Nerves that release acetylcholine are called cholinergic nerves. Neurotoxins are substances which alter the function of the nervous system by damaging brain cells or the nerves which carry signals around the body. Your nervous system contains millions of nerve cells, called neurons. Neurons are highly specialised to transmit messages from one part of your body to another. Sensory neurons, which pass information about stimuli such as light, heat or chemicals from both inside and outside your body to your central nervous system. Since the nervous system innervates all areas of the body, some toxic effects may be quite specific and others generalized depending upon where in the nervous system the toxin exerts its effect. Among the most well-known are: Acetylcholine. Dopamine. Serotonin. Norepinephrine. There are two kinds of cells in the nervous system: glial cells and neurons. Glial cells, which make up the support structure of the nervous system, perform four functions: Provide structural support to the neurons. Insulate neurons.

The prognosis depends upon the length and degree of exposure and the severity of neurological injury. In some instances, exposure to neurotoxins or neurotoxicants can be fatal. In others, patients may survive but not fully recover. In other situations, many individuals recover completely after treatment.

Neurotoxicity was reversible in 60% of the patients; however, 40% developed permanent disability after treatment.

Treatment involves eliminating or reducing exposure to the toxic substance, followed by symptomatic and supportive therapy. Treatment involves eliminating or reducing exposure to the toxic substance, followed by symptomatic and supportive therapy.

Toxins, poisons and chemicals can cause peripheral neuropathy. Common toxins that cause neuropathy include: exposure to lead, mercury, arsenic and thalium. Some organic insecticides and solvents can result in neuropathies. Sniffing glue or other toxic compounds can also cause peripheral neuropathy.

Chemicals like lead and mercury can also be toxic. Exposure to molds, cleaning solvents, pesticides, and even air fresheners can sometimes be harmful. Of course, some toxic episodes result from drug and alcohol abuse, and over time, repeated substance abuse can lead to toxic brain injuries.

https://en.wikipedia.org/wiki/Neurotoxin

Neurotoxins are an extensive class of exogenous chemical neurological insults that can adversely affect function in both developing and mature nervous tissue. Neurotoxins inhibit neuron control over ion concentrations across the cell membrane, or communication between neurons across a synapse.

https://en.wikipedia.org/wiki/Neurological_disorder

A neurological disorder is any disorder of the nervous system. Structural, biochemical or electrical abnormalities in the brain, spinal cord or other nerves can result in a range of symptoms. There are many recognized neurological disorders, some relatively common, but many rare.

Neurotoxicity occurs when toxins (manmade or biological) accumulate in the neurological tissue of the body and undermine the functioning of the brain and nervous system. Long-term exposure to radiation, chemicals, food additives, pesticides, and other naturally occurring substances can all cause neurotoxicity.

Your nervous system has lots of protection. Your brain is guarded by your skull, and your spinal cord is shielded by small bones in your spine (vertebrae) and thin coverings (membranes). They're both cushioned by a clear fluid called cerebrospinal fluid.

Central nervous system: The central nervous system (2) is a combination of the brain (1) and the spinal cord (3). The CNS is covered with three layers of protective coverings called meninges (from the Greek word for membrane). The outermost layer is the dura mater (Latin for “hard mother”).

https://www.ck12.org/book/cbse_biology_book_class_x/section/2.5/

The brain is covered by three protective layers called meninges. The space between the meninges is filled with a fluid called cerebrospinal fluid. This fluid protects the brain against shocks and mechanical injuries.

The brain is protected by the bones of the skull and by a covering of three thin membranes called meninges. These bones protect the spinal cord. Like the brain, the spinal cord is covered by the meninges and cushioned by cerebrospinal fluid.

Summary: Spinal cord injuries can cause widespread and sustained brain inflammation that leads to progressive loss of nerve cells, with associated cognitive problems and depression, researchers have found for the first time. "The brain degeneration was demonstrated in different experimental models and animals.

The spinal cord is the relay and integration center for your central nervous system, sending signals to and from the brain and aiding in vital reflexes. This means that a spinal cord injury can affect every region of your body. Thus almost every area of the body can be affected by a spinal cord injury.
