Also, there are few species which have a stronger venom that could potentially be fatal or at least make the bite victim quite ill. 1  So while tarantula bites are unlikely to be fatal, you still want to avoid being bitten and the best way to do this is to learn about spider behavior and treat the spider accordingly.
To consent is to give permission, which could have been withheld. It implies a power relationship where the consent is granted by the party with more power. There is the political theory that says, governments can rule only with the consent of the governed. That is, the people consent to be governed and thus grant their power to the government. To assent is to agree with a statement made by an equal. On the Supreme Court, one justice writes the opinion of the majority, to which other justices assent. Those that disagree are said to dissent, that is to disagree. So, consent = permission while assent = agreement.
Assent means that they agree to take part. They may also dissent, which means they do not agree. Unlike informed consent, assent is not always required by law, though IRBs may require it. To take part in the assent process, children must be mature enough to understand the trial and what they are expected to do. Some children as young as 7 years old may be able to take part.
