The action of polypeptides upon ion channels and receptor sites of excitable membranes through signal transduction causes the release of neurotransmitters which results in neuromuscular effects.

What is toxicological studies?

Toxicology studies are used to characterize the toxicity profile of a drug by identifying its impact on organ structure and / or functionality. This includes assessment of the severity and reversibility of toxicity, as well as dose ranges and their relationship to exposure.

No-observed-adverse-effect level (NOAEL) Greatest concentration or amount of a substance, found by experiment or observation, which causes no detectable adverse alteration of morphology, functional capacity, growth, development or life span of the target organism under defined conditions of exposure.

What are systemic poisons?

A systemic pesticide is any pesticide that is absorbed into a plant and distributed throughout its tissues, reaching the plant's stem, leaves, roots, and any fruits or flowers. Systemic pesticides are water-soluble, so they easily move throughout a plant as it absorbs water and transports it to its tissues.

What are physical toxins?

Physical toxicants are substances that, due to their physical nature, interfere with biological processes. Examples include coal dust, asbestos fibres or finely divided silicon dioxide, all of which can ultimately be fatal if inhaled.

What are the two types of toxicity?

The two types of toxicity are acute and chronic. Acute toxicity of a pesticide refers to the chemical's ability to cause injury to a person or animal from a single exposure, generally of short duration. The four routes of exposure are dermal (skin), inhalation (lungs), oral (mouth), and eyes.
