Hello, there.
00:03
I see there are a list of questions.
00:05
So let's go over the first part where they want us to tell us what you know about pain, bare nerve endings or pain receptors that are lightly myelinated and are also recognized hot or cold or acids.
00:24
Well, there are four types of pain receptors.
00:28
So four types are here.
00:34
Mechanical receptors.
00:40
This is also including, this is also, including, including this is your pro pro pro pro pre receptors, i mean, exceptions.
01:02
This one, the next one is your nociceceptors, your thermal receptors, and your chemoreceptors.
01:22
So with these receptors, so your mechanical receptors, this is where they notice physical changes.
01:41
Then your neck nocice receptors, they're basically are sensitive to pain causing stimuli, such as heat, cold, excessive pressure, inflammatory chemicals.
01:55
Your chemo, your thermal receptors, of course, folks on temperature.
02:06
I did bring up like the no -siceptors.
02:14
They recognize pain, my bad, and your chemoreceptors, they respond to, oops, did not mean to do that.
02:23
They respond to chemicals such as smell, taste, and changes in blood.
02:30
Chemistry so that's what we know about that part where i can recognize all those things that's why there are different receptors and then about the bare nerve endings or like they like to call them free nerve endings so it depends on either or you want to use those up to you which one you choose to cause so you can say free nerve ending or you can say bare nerve ending like either way you could choose either or um it's basically um an unspecialized afferent fiber sending its signal to a sensory neuron and a afferent is basically it basically means like binding information from the body's um p -right furry um towards the brain periphery towards the brain so that's it that we can tell about with that um the next one they want to know how are pain fibers different um they are different because with pain fibers they're like how they are different of oh sorry did not mean to write that part okay they are different because the the unmyelated c fibers respond to thermal mechanical and chemical stimuli let me erase that's supposed to be an eraser and produce the sensation that's supposed to be a s it was there go because i wasn't supposed to connect sensation of do diffuse aching burning and delayed pain and and they have different types of pain fibers where you have a beta.
06:36
You have a beta.
06:38
Okay, beta.
06:40
Okay, a delta.
06:47
And c fiber.
06:53
So the different types.
06:54
So fiber a could be responsible for the sharp, well localized pain in human subject.
07:03
Well, fiber c could be responsible for the dull.
07:06
Pain radiating and other parts of the body.
07:10
So these two handle sharp pain...
