One type of poison arrow frog toxin binds specifically to nicotinic cholinergic receptors and causes tetanic paralysis of the muscle. Would the poison arrow frog toxin increase or decrease autonomic output? Explain your answer choice based on neurotransmitters and receptors on the pre-and postganglionic neurons in the sympathetic and parasympathetic nervous system.
