Another toxin that also blocks neurotransmitter release is tetanus toxin; however,it primarily affects inhibitory interneurons of the spinal cord that negatively regulate motor neurons.Which would be symptoms of tetanus toxin poisoning?
A)flaccid paralysis
B)spastic paralysis
C)slowed action potential conduction
D)pupil dilation

Question

Quizplus · Accepted Answer

Tetanus toxin primarily affects inhibitory interneurons, leading to an excessive activation of motor neurons and muscle spasms, which is characteristic of spastic paralysis. Flaccid paralysis is generally caused by toxins that primarily affect motor neurons themselves, such as botulinum toxin. Slowed action potential conduction and pupil dilation are not typical symptoms of tetanus toxin poisoning.
