Which symptom would most likely occur in an organism exposed to tetrodotoxin

The right naswer is D.paralysis due to lack of action potentials to signal muscle tissue.

Tetrodotoxin (TTX) is a toxin (neurotoxic) isolated for the first time in 1909 and present in some species of fish, tetraodons.

It is also called Fugu poison, and tetraodon poison.

Tetrodotoxin is a potent neurotoxin produced by four different strains of bacteria: Aliivibrio fischeri, Pseudomonas sp, Vibrio altermonas and Vibrio alginolyticus.

Tetrodotoxin selectively blocks the pore of voltage-gated sodium channels, thus preventing the passage of nerve impulses. This blockage under a certain level is reversible.

The clinical picture is as follows:

* Impairment of the nervous system with oral and perioral paresthesia, nausea often accompanied by vomiting, sometimes with diarrhea and abdominal pain;

* Dizziness, pallor, feeling unwell, then ataxia and general numbness with the sensation of floating. * Tingling and tingling of the extremities preceding paralysis of the lower limbs and extremities;

* Changes in deep sensitivity, throat and larynx are affected very early causing dysphagia or complete aphagia, and dysphonia;

* Dilation of the pupils (mydriasis);

in the case of acute intoxication, bradycardia and hypotension, hypersalivation, hypothermia, hypersudation, asthenia;

* Cyanosis of the extremities and the lips, petechial haemorrhages on the body.
