Hello everyone, so here we are given a series of questions which is of lengthy question.
00:07
So the first question here asked is, a josh who ran in the new york city marathon, he noticed while his legs were moving in normal automatic rhythm, he was still able to relax and think about other matters.
00:21
So here in the case of josh, there is the muscular movement, also there is the coordination of thinking i .e.
00:37
He is able to think about some other matters.
00:41
So we are here asking, what part of the brain is most likely in charge of the movement of his legs as he left his mind wander? so the part of the brain which is responsible for this muscular movement along with the other basic functions is the medulla.
01:02
The part of the brain which is known as medulla is responsible for coordinating both the muscular movement along with the basic functioning such as heartbeat, breathing etc.
01:15
Now 19th question here asked is, saltatory conduction is seen in dash axons and is caused by the action potential occurring in dash.
01:33
So the saltatory conduction is usually seen in myelinated axon and is caused by the action potential which is occurring in the rod of ranvir.
01:57
Actually it is not rod, it is nod of ranvir.
02:01
So by chance there is a mistake in the question, our answer will be nod of ranvir.
02:08
Now next question here asked is, which is marked as question no.
02:14
22.
02:15
The release of an activating neurotransmitter from one pre -synaptic neuron is most likely to cause an epsp reaction.
02:49
Epsp means excitatory post -synaptic potential.
03:04
This is the epsp reaction.
03:05
So the epsp reaction is the activation of the neurotransmitter potential...
