Should you, God forbid, need a heart transplant you will opt for a clump of cells that manifests some electrical activity or a fully formed 4-chambered heart ? Remember your reliance on a John Hopkins website in making your choice.
A childs bones havent fully developed when they are born, but we still call them bones. All a fully developed heart is, is a larger clump of cells that has completed its full journey. A developing heart is still a heart. Someone upthread refered to it as just cardiac activity. Definition of cardiac (Entry 1 of 2) 1a: of, relating to, situated near, or acting on the heart Also of note, a fully developed heart should not be our criteria. Hypoplastic left heart syndrome is a rare heart defect present at birth (congenital). In this condition, the left side of the heart is extremely underdeveloped. Hypoplastic left heart syndrome - Symptoms and causes
Just because the language hasn't developed a different word for something doesn't mean approximate shorthand for it changes what it is.
Medical science can't come up with a term for an undeveloped heart and actually use it? They have it for everything else. Thats where the argument is now lol. Eye Roll indeed.
No, they can and have but the ideas on public facing website need to be accessible to a broad spectrum of the public. I have struggled mightily to provide web content on technical subject matter much less complex than human development and it is hard. They could have provided a short course in embryology that would necessarily go into much irrelevant detail and go far beyond their mandates for word count and grade level comprehension or just shortcut things and call it a heartbeat.
Again, go look at who is saying there is a heartbeat at 6 weeks. Get back to me proving they are all wrong. I’m going with them over the keyboard doctor.
1 more: "Yes, virtually every hospital will call it a heartbeat in patient facing webpages. And when talking with expectant parents." OK, you've convinced me that first part of the sentence about a heartbeat was a dumb thing to say as well given that 99% of voters would be laypeople.
So you choose a clump of presumptive cardiac muscle cells over a fully formed heart for you transplant donor? Things are not going to go well for you. The heart beat heard when a stethoscope is placed on a persons chest is the lub-dub of heart valves closing. In a 6-week old fetus there is no heart and there are no valves. There is some electrical activity that we have developed the technology to produce a sound from. But there are no valves and there is no heart.
Again, an idiotic comment by Abrams. Why she is even making scientific comments about the formation of the heart of an unborn child when she supports no limits on abortion anyway makes no sense. Stacy Abrams has proven to be a poor politician and needs to learn sometimes it is best she keeps her mouth shut rather than speak out on a scientific subject of which she has absolutely no expertise.
And she will probably do it again although ironically she will most likely end up losing her own election.
https://www.washingtonpost.com/poli...at-further-inflames-tensions-abortion-battle/ So does a 6-week-old embryo have a heartbeat? Medical professionals note a distinction between the sound heard early in pregnancy compared with later further development of the heart. Nisha Verma, a member of the American College of Obstetricians and Gynecologists (ACOG), which supports abortion rights, puts it this way: A heartbeat is the sound created by the opening and closing of cardiac valves. But what people think of as a heartbeat in early pregnancy is actually created by electric impulses that are captured by an ultrasound machine and translated by the machine into the sound of a heartbeat — there are no cardiac valves, so there is no sound of them opening and closing. * * * ACOG’s Verma acknowledged that she and other physicians use the word “heartbeat” with their newly pregnant patients — and believes it’s perfectly fine to do so. She compared it to using the word “stomach bug” to refer to what is medically known as gastroenteritis. “That is language they connect with, they understand,” Verma said. “It doesn’t have to be medically precise.” ------------------------------------------------------- As a lawyer, the bold makes perfect sense. I sometimes have to explain legal concepts to laymen in presentations to the public or while speaking to the media. To do so effectively, I have to strip away some of the nuance to put it in terms people will understand. That oversimplification allows people to understand the concept, but it also means that it's not fully correct.
Again, Tilly posted 6 Major medical centers and a countries health agency showing there is a heartbeat at 6 weeks. It's ok to say "my bad" and move on. But continue going down with the ship. Funny to watch.
There is no heart and there are no valves to beat at fetal development of 6 wks.No amount of your snark changes that.
Ok Dr. Again, just let me know when Johns Hopkins, NYU Health, UF Health and the NHS change when a heartbeat starts. Don't know if it's ignorance or you just being obtuse. Funny to see though.
I am still not clear if the electric signals are actually producing a very, very faint "real" sound which is merely amplified (made louder) to be audible to human ears or if the machine is fabricating an artificial sound entirely when there is no sound at all at that stage of development.
