Paralysis in The Animal World
Many animal species use paralyzing toxins to capture prey, evade predication, or both. It was shown that in stimulated muscles the decrease in frequency of the miniature potentials runs parallel to the decrease in postsynaptic potential as well as to the decrease in muscle contraction. This clearly indicates that Microbracon venom causes paralysis of the neuromuscular system by acting at a presynaptic site. Philanthus venom inhibits the fast as well as the slow neuromuscular system at identical concentrations. It causes a decrease in the frequency of the miniature potentials without affecting their amplitude significantly

Famous quotes containing the words animal and/or world:
“The moose will, perhaps, one day become extinct; but how naturally then, when it exists only as a fossil relic, and unseen as that, may the poet or sculptor invent a fabulous animal with similar branching and leafy horns ... to be the inhabitant of such a forest as this!”
—Henry David Thoreau (1817–1862)
“If I had influence with the good fairy who is supposed to preside over the christening of all children, I should ask that her gift to each child in the world be a sense of wonder so indestructible that it would last throughout life.”
