How Does Tetanospasmin Affect Motor Control

Question

How does tetanospasmin affect motor control?
A) It blocks the secretion of acetylcholine into the synaptic cleft.
B) It blocks the release of inhibitory neurotransmitters in the CNS.
C) It triggers the endocytosis of skeletal muscle cells.
D) It induces nervous system proteins to fold into abnormal shapes.
E) It is a pyrogenic toxin.

Accepted Answer

Tetanospasmin blocks the release of inhibitory neurotransmitters in the CNS, leading to increased muscle contraction and spasms. This occurs because inhibitory neurotransmitters normally prevent excessive muscle contraction.
