Document Summary

Under influnece of action potential, nerotransmitters are released into the synaptic gap. The neuro transmitter are no longer protected by cell membrane. The neurotranmitters are no longer pr neurotranmitters travel to post-synaptic neurons or muscle cells specialized receptors ca(cid:374) (cid:862)recog(cid:374)ize(cid:863) the che(cid:373)ical code of the (cid:374)eurotra(cid:374)s(cid:373)itter the neurotransmitter blinds to the post-synaptic receptors. Excitatory or inhibitry effects the neurottanmitter will have long-term effect unless its actions are terminated. An excitatory neurotransmitter will increase the likelihood that the post-synaptic cell will fire. An inhibitory neurotransmitter will decrease the likelihood that the post-synaptic cell will fire. Resting potential becones more ngatively charge than normal. Increase in the critical threhold for the firing the action potential of the post- synaptic neuron. Ach is generally excitatory on membranes of skeletal-muscle fibers. Nerve gas may block receptor site, or interfere with reuptake. Endorphins the nobel prize 1906 c. golgi & s. ramon y cajal.
