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:
“All that is told of the sea has a fabulous sound to an inhabitant of the land, and all its products have a certain fabulous quality, as if they belonged to another planet, from seaweed to a sailor’s yarn, or a fish story. In this element the animal and vegetable kingdoms meet and are strangely mingled.”
—Henry David Thoreau (1817–1862)
“We have grasped the mystery of the atom and rejected the Sermon on the Mount.... The world has achieved brilliance without wisdom, power without conscience. Ours is a world of nuclear giants and ethical infants.”
—Omar Bradley (1893–1981)
