The neurotoxin tetanospasmin,which produces the condition tetanus,invades the central nervous system by
A) passing through the blood brain barrier.
B) traveling via anterograde transport along microtubules.
C) traveling via retrograde transport along microtubules.
D) traveling via retrograde transport along neurofilaments.

Question

Quizplus · Accepted Answer

Tetanospasmin enters nerve cells at the site of infection and travels along axons retrogradely towards the central nervous system. Retrograde transport is facilitated by binding to specific receptors on the membrane of nerve cells and then using the dynein motor proteins to travel down microtubules towards the cell body.
