How about the cardiac plexus? The RLN's have nerve fibers there.

Starting today August 7th, 2024, in order to post in the Married Couples, Courting Couples, or Singles forums, you will not be allowed to post if you have your Marital status designated as private. Announcements will be made in the respective forums as well but please note that if yours is currently listed as Private, you will need to submit a ticket in the Support Area to have yours changed.
Are you ever going to admit that the cardiac ganglion does NOT send motor information to the larynx? Or are your own sites used for 'support' also in error?
Yes - because there is no such thing as a "mechanical neuron".
You, and many others who argue with me, misconstrue my comments so that you will have something to argue about. If you read them carefully you would likely agree with me, or at the least not disagree.
Excessive breaking up posts is rude. And when corrected learn from your mistakes. Do you think that you can do that? If you can then may be we can have a discussion.
Always.
Hey hey my sagacious dear
That is cool and i think u r 2
I would like to properly, politely and respectfully ask you if you believe evolution is a random process and how do you define random process?
Cheers you
I have backed out of nothing. I gave you the long-standing scientific definition of "random" and provided a reputable source. I can't help it if that definition undermines your sophistical argument.
Your question is poorly formed random at what level?
There are random elements to it, but it is far from random.
Life will react to changing environments, that will change how life evolves.
But there are some similarities that are governed by environment. Look at the lizards known as ichthyosaurs. Fish sort oas Tuna and sharks, and mammals like dolphins. They all have similar shapes due to the environment that they inhabit, but very different interiors.
Questions such as this do not really have a "yes or no" answer.
Faith to me, is something that is personal and does not have independent outside evidence to support. That is how i use the term.
I dont need faith to trust or rely on science, because i enjoy the conveniences of science everyday
(as do you)
and the results keep producing the same results independent of my personal observations and are reliable.
You see, i dont need faith the light switch will turn the lights on when i flip the switch, because the is a proven track record of objective and reproducable results.
I do need faith, that i will win lotto one day, because a reliable track record or objective evidence this will happen, is scant.
What evidence do i need? I have indicated this numerous times; the claim of a christian god and the attributes applied to this god, is a pretty amazing claim. For me to believe this is true, will require an equal amount of amazing evidence and i dont mean, stories written by anonymous authors, decades after the events claimed to have happened, personal claims by people who talk about their belief, threats that those who dont believe are doomed (quite childish the threats).
Humans have manufactered god claims for thousands of years, nothing new there.
From a psychology standpoint, not difficult to see how some grab onto whatever god or religion that suits them, when they are presented with threats if they dont,
and eternal life if they jump onboard.
When we had little knowledge of the world,
you can see how faith and religious beliefs would bring comfort.
Dont worry though, no matter what anyone else thinks, you are free to believe what you believe.
I am not going to nitpick over definitions either, and unlike most creationists I am not afraid to admit that there are others here that know the topic better than I do. Of course I also can see that I do understand this better than our creationists here.Yes, abundant evidence.
I don't remember it and don't care in any case. As I have said repeatedly, I'm happy to tell you about evolution. I have no interest in debating definitions of words.
Same answer.
That is because you are ignorant of all things biological. 'Warning signal to the throat'? You thought it was the gut because you do not understand biology.So, when you're about to vomit it's the brain sending the warning signal to your throat? I thought it was the gut.
Gee, golly, I guess nobody ever thought about such a thing.How much research has been done on neural pathways during upchucking?
No I really wouldnt. I disagree very much with your abhorent values.
Of course, as an atheist, you would disagree with Christian values.
Whose Christian values? Not all Christians appear to have the same ones.
Maybe, values tend to be very individual regardless of religion or lack thereof.
There are only so many 'values'. It's how one exercises them that counts. Some believe in love, others in tough love. To the 'lover' tough love isn't love, but hate. It can be very confusing.
I really dont care, I just find yours abhorent, not christians in general.
That is because you are ignorant of all things biological. 'Warning signal to the throat'? You thought it was the gut because you do not understand biology.
Do you not even read the websites that YOU link to and quote?
"The “afferent” (flowing to the brain) parasympathetic information travels from the heart to the brain through the vagus nerve to the medulla, after passing through the nodose ganglion. The sympathetic afferent nerves first connect to the extrinsic cardiac ganglia (also a processing center), then to the dorsal root ganglion and the spinal cord. Once afferent signals reach the medulla, they travel to the subcortical areas (thalamus, amygdala, etc.) and then to the cortical areas."
Same for vomiting. My gosh - you have the Google, yes?
Google "vomiting center".
Gee, golly, I guess nobody ever thought about such a thing.
Obviously, the gut must send vocalization signals directly to the larynx via the RLN, what a grand Creation!
"The noxious stimulus may cause release of serotonin from enterochromaffin cells of the digestive tract, which activates visceral afferents. The vagus nerves mediate responses from the stomach and proximal small intestine and the splanchnic nerves and spinal cord mediate responses from the entire small intestine. Emesis-related afferents from the periphery terminate primarily in the nucleus tractus solitarius and area postrema."
Nucleus tractus solitarius
Area postrema
Isn't it amazing how much information is actually out there, should one care to actually look for it and LEARN about it, rather than pontificating in the dark?
Oh - don't forget:
What is the purpose of the heart sending signals directly to the esophagus?None, because it doesn't.
"The extrinsic cardiac ganglia, located in the thoracic cavity, have direct connections to organs such as the lungs and esophagus and are also indirectly connected via the spinal cord to many other organs, including the skin and arteries."Umm... This is sort of hilarious to me.
Does the heart have to communicate with the brain to both manage itself and the function of other organs?
A cautionary tale on drawing conclusions after reading things in fields you have no demonstrable skill, education, or experience in.
You see, "cardiac" means 'pertaining to the heart', and in this context, refers to a region, i.e., 'near the heart'. Extrinsic means 'external to'. These ganglia are outside of the heart, and provide innervation to the heart AND to other organs. The heart does not use them to "manage itself and the function of other organs". Victoria Station, for example, does not allow only Victoria to get on trains...
The stomach has a 'cardiac region' (aka, 'cardia') - do you think this means that the stomach has its own heart?
Weird that you apparently stopped reading that webpage after you found your quote - a bit later, we see:
"The “afferent” (flowing to the brain) parasympathetic information travels from the heart to the brain through the vagus nerve to the medulla, after passing through the nodose ganglion. The sympathetic afferent nerves first connect to the extrinsic cardiac ganglia (also a processing center), then to the dorsal root ganglion and the spinal cord. Once afferent signals reach the medulla, they travel to the subcortical areas (thalamus, amygdala, etc.) and then to the cortical areas."Nothing about stopping off at other organs. Or sending motor impulses to the larynx. Tell us - did you really just stop reading that when you got the quote you wanted, or did you read the whole thing and not understand it? or not think it mattered? Or hoped that nobody would be able to find it? I don't understand how you operate. It seems rather self-defeating.
