Question

How does tetanospasmin act?A) it is a pyrogenic toxinB) it blocks the release of inhibitory neurotransmitters in the CNSC) it blocks the secretion of acetylcholine into the synaptic cleftD) it induces nervous system proteins to fold into abnormal shapesE) it triggers the endocytosis of skeletal muscle cells

Answer 1

Answer: B) it blocks the release of inhibitory neurotransmitters in the CNSC)

Explanation:

Tetanospasmin is a neurotoxin it is associated with the inhibition of inhibitory neurotransmitter called as GABA (γ-aminobutyric acid). The GABA is a widely distributed neurotransmitter which is distributed to the neurons of the cortex. This is associated with the variety of clinical signs such as tetanus, muscular spasm, rigidity, lockjaw, tendon rupture, respiratory difficulty, dysphagia, difficulty in respiration and death.
