Question

what is synapse??????????

Answer 1

$\huge \textbf{hello}$

$\textbf{here \: is \: your \: answer}$

$\huge \underline \textbf{synapse}$


Synapse is the junction between two neurons or neuron -neuron contact is called synapse.


'OR'


The synaptic knob of one axon present in close contact with dendrite of other neuron this contact point is known as synapse.


'OR'

The contact between axon of one neuron and muscle cell or gland is also known as synapse.


*The Word Synapse was coined by
$\underline \textbf{Sir Charles Sherrington}$

$\underline \textbf{Synaptic cleft}$

Synaptic cleft is the space present between dendrite of one neuron and axon of other neuron.

Answer 2

$\huge\green{Hello there }$

__________

$\huge\blue{SYNAPSE }$

The junction between axon terminal of one neuron and tge dendrite terminal of another neuron , where infirmstion is being transmitted or relayed to another neuron , but there is no cytoplasmic connection between the two neurons instead a microscopic gap is present .

$\huge\red{TYPES OF SYNAPSE }$

1 ▪ Electrical synapse

2▪ Chemical synapse

$\huge\red{ELECTRICAL SYNAPSE }$

In electrical synapse impulse , which are specialized for rapid signal transmission , the cells are separated by a gap , the synaptic cleft , for only 0.2nm , so that an action potential arriving at the pre synaptic membrane directly trigger its action potential .

$\huge\pink{CHEMICAL SYNAPSES }$

The majority of synapses are chemical synapses where synaptic cleft has gap of more than 20nm , through these synapses information of impulsebfrom one neuron is transmitted to another by means of chemical messengers , the neurotransmitters .
