Document Summary
Neuron but because it does not occur in a neuron we do not call it such. *4 ap is a k+ channel blocker. So, epp is directly proportional to a postsynaptic. Quantal release is the smallest amount of nt that is ever going to be released. Each mepp is the smallest amount of nt that is ever going to be released. Quanta referred to the height of one mepp. you cause ap in presynaptic neuron . Each epp is a (cid:498)packet(cid:499) of multiple mepps. Number of quanta released = smallest change in postsynaptic cell"s voltage. *otto loewi"s experiment proved that there is a chemical message being released into the water in the first frog heart chamber that tells the heart to speed up or slow down. more ca2+. membrane. little longer. Due to higher concentration of 4 ap, there are more vesicles fusing to the plasma. When aps are being fired you can see the vesicles fusing with plasma membrane.
