Argument Episode on Understanding Brain and Nervous System ji

Then we entered into the very Interesting session of the discussion .

According to @Misbah and me neurons and nerve cells are the same .But @Ichha had opinion that both are different .According to @Ichha neurons are collectively called nerves .Then also @Smiti had a opinion that neurons and nerve cells are the same .
Also @Smiti tried to analysis the response of touch using hot object
According to @Smiti One neuron is involved in the whole process .
Like Hot object >One neuron > Spinal cord

But i think there are more neurons are there to carried out the transmission of signals.

Then @Tuba tried to explaining about the transmission of signals from one neuron to other .

In this picture we have 2 neurons ,Blue one is the pre-synaptic neuron and Red one is the post synaptic neuron .
In between there is a space called Synapse .Also in axon terminal there is a neurotransmitter which helpful for the transmission of electrical signal to chemical signal and then to electrical signal.@Tuba

Why such complication is there !?

What is the actual process there in synapse !?

According to @Ichha ⁩ there are more neurons ,So these synapse can also check if there any problems in the signal and also there by prevent the transmission .

But according to @Smiti one neuron is enough ,more neurons will cause the delay of signals.Touch response is a reflex action .So sudden response is possible only when there only one neuron that connect to spinal cord.

@KiranyadavR ⁩ also mentioned about the size of the neurons.

Size of the neuron is from several mm to m.

The longest neuron in the human body has a single threadlike projection (the axon), a few micrometers in diameter, that reaches from the base of the spine to the foot, a distance of up to one meter." For axon length of over a meter see Cavanagh (1984, PMID 6144984 p.1284 right column bottom paragraph:) " Length of neuron from base of spine to big to - Human Homo sapiens - BNID 104901

Also discussed about the neurotransmitter acetylcholine,According to me this is a protein but @Ichha ⁩ had a opinion that choline is something similiar to cholestrol. So that may be a lipids .

Yesterday we learned a lot from people who having different concept about neuron and its function, infront of a neuroscientist.

Questions still remaining

What is the actual process there in synapse !?

How many neurons taking part in a nervous system !?

Acetylcholine is a protein or lipid !?
