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:
“... found myself
myself, smaller,
not thin but thinner, nervous,
who hurries without animal calm.”
—Denise Levertov (b. 1923)
“... women of the North, I ask you to rise up with earnest, honest purpose, and go forward in the way of right, fearlessly, as independent human beings, responsible to God alone for the discharge of every duty, for the faithful use of every gift, the good Father has given you. Forget conventionalisms; forget what the world will say, whether you are in your place or out of your place; think your best thoughts, speak your best words, do your best works, looking to your own conscience for approval.”
—Susan B. Anthony (1820–1906)
