Question

i provide u 50 points please i need whole process of Impulse transmission at synapsis..? please don't google it googled answer will be deleted soon​

Answer 1

at synapse of two neurons . the electric impulse from one neuron setts off and releases a chemical . that chemical travels through synapse to the dendrite of next neuron and the next neuron use that chemical to generate electric impulse again .

then this process continues.

Answer 2

Hey mate here is yur ans...

●$\textbf{Impulse transmission at synapsis.}$

• $\textbf{Synapsis}$ are the joints of $\pink{neurone.}$ at synapsis the $\blue{1st neurone}$ is called $\textbf{Pre-synaptic neurone,}$ It's $\orange{membrane}$ is called $\textbf{Pre-synaptic membrane.}$

• $\pink{2nd\:neurone}$ is called $\textbf{post-synaptic neurone.}$It's $\orange{membrane}$ is called $\textbf{Post-synaptic membrane.}$

> $/textbf{Synapsis}$ are of 2 types.

▪ $\textbf{Chemical synapsis:-}$

◇ Discovered by $\green{sharrington,}$ ,Physiology of $\red{electrical\:synapsis}$ is discovered by $\red{Henry dale.}$

> In $\textbf{Chemical synapsis(C.S)}$ there is a gap b/w $\red{Pre}$ and $\pink{Post}$ Synaptic membrane. it is called $\textbf{Synaptic cleft.}$

• The $\red{axone terminal}$ of $\textbf{Chemical synapsis}$ of Pre-synaptic membrane consists many $\orange{Secretary vesicles}$ containing $\textbf{neurotransmitors.}$

• $\textbf{Post-synaptic membrane}$ of $\textbf{Post-synaptic neurone}$ bear many receptor sites containing receptor $\blue{proteins\:molecule.}$

> When impulse reached at the end of $\textbf{Pre-synaptic neurone,}$, $\red{Ca+2\:gated\:channels}$ also open along with $\pink{Na+ \:channels.}$ Ca+2 influx occurs from $\textbf{E.C.F}$ therefore $\textbf{I.C.F}$ of axone terminal.

> Ca+2 ions bind on the surface of $\textbf{Secretary vesicles}$ passing them towards $\red{Pre-synaptic\:membrane}$ $\textbf{Secretary vesicles}$ fused and released neurotransmitors into synaptic cleft by $\green{exocytosis.}$

> $\textbf{Neurotransmitors}$ are bind on $\orange{receptor\:molecules}$ of $\textbf{Post-synaptic membrane.}$ therefore This membrane also get excited, It's $\red{Na+\:channels}$ open,, $\textbf{Na+ influx}$ begin and $\yellow{depolarisation}$ occur at $\textbf{Post-synaptic neurone }$also.

> The intensity or amount of impulse in $\textbf{Post-synapyic neurone}$ is less or more than $\textbf{Pre-synaptic neurone.}$

> It depends on type of $\pink{neurotransmitors}$ and $\blue{receptor\:sites.}$

> $\textbf{impulse transmission}$ at C.S is $\red{unidirectional}$ that is from $\textbf{Pre to Post Synaptic neurone.}$

> C.S is formed in both C.N.s and P.N.s.
