What is the physiology that explains how a high heart rate influences coronary artery perfusion and myocardial oxygen delivery?

What is the physiology that explains how a high heart rate influences coronary artery perfusion and myocardial oxygen delivery?

Circular question: By itself, a high heart rate will result in higher oxygen demand and utilization, but delivery should also increase to compensate. So everything should balance if the heart is healthy. If the heart isn't healthy to begin with a high heart rate is not desirable. ...Read more

What does the uterus is anteverted and in position measuring 9.2x6x5 CM . The uterus is regular and contour and heterogeneous in echogenicity mean ?

What does the uterus is anteverted and in position measuring 9.2x6x5 CM  . The uterus is regular and contour and heterogeneous in echogenicity mean ?

Anteversion just : Means tilt (normal) and the size of the uterus is normal. Heterogeneity is a nonspecific term that means not all of the uterus looks the same. The report should indicate what (if any) significance there is to this finding. Uterine heterogeneity can be seen with uterine fibroids and adenomyosis (both of which can be associated with pelvic pain and other symptoms). ...Read more

30 week ultrasound showed asymmetrical brain ventricles on fetus. Rest of the scan perfect. Is this a normal variant?

30 week ultrasound showed asymmetrical brain ventricles on fetus. Rest of the scan perfect. Is this a normal variant?

Not really.: No, this is not a normal variant and is usually indicative of some type of compromise and blood flow, to the side of the brain where the ventricle is more prominent. The good news, is that a fetus's brain is very resilient, and as long as all else goes well from here on in, the baby can develop normally. ...Read more

How can organisms similarities in anatomy and embryology provide evidence for evolution?

How can organisms similarities in anatomy and embryology provide evidence for evolution?

Ontogeny recapitul-: ates phylogeny. That means that during embryonic development, the embryo goes through physical forms that mimic your ancestors, rather than just develop right into a human. An early human embryo looks very much like our amphibian and then dinosaur (well, chicken, which is really the same thing) ancestors, and then many early structures wither and die, being replaced by more advanced species. ...Read more

Why don't physiology books show refraction at the anterior surface of the cornea?

Too specific.: A general physiology book already has a lot to cover without delving into physiologic optics. If you want to dig deeper, check out general optics texts to understand basics like indices of refraction, followed by eye anatomy and physiology texts. The bscs series volume on cornea is helpful. Finally, texts about corneal topography, higher-order aberrations, and lasik would be fun. War eagle! ...Read more

What is the function of fossa ovalis in embryonic human heart and why it becomes foramen ovale?

No function in adult: This is the adult anatomic footprint of the normal path of oxygenated blood from the uterus to bypass the fetal lungs & provide oxygen to the fetus's body. This path is in the wall between the fetus's left & right atria. At birth, this hole immediately closes, putting baby blood in the lungs. In adults, this closure may not be complete (patent for amen ovale) & blood may shunt across the atria. ...Read more

It means you should: NOT let a surgeon get near you with a 10 Foot Laser, tin foil, or anything else to try and cure your Facial or Ear discomforts until you've tried all possible conservative treatments and management strategies.

My fibroid uterusis 5.3cm with myomas in anterior wall and the ovaries are normal, what does that mean?

My fibroid uterusis 5.3cm with myomas in anterior wall and the ovaries are normal, what does that mean?

You have a fibroid!: Anyone can get a uterine fibroid, which is an overgrowth of muscle cells in the shape of a ball. Like moles on the skin, they come in different sizes/shapes; RARELY cancerous. You only need surgery if you have symptoms like pain/pressure/incontinence/bleeding/bloating. Size/location don't matter. Lupron (leuprolide) or embolization are ways to control w/out surgery. US follow up is very important. ...Read more

Had anatomy scan showed lowlying posterior placenta.19+3wks.Can this harm bub?Chances of moving?How can I help?I know c-sect is a possibility.worried

Do not worry: This is not an uncommon finding. Low lying placenta will not harm the baby. It is very likely that with advancing pregnancy, the placenta will no longer be low lying. Most likely your OB will advise a follow up ultrasound to check on this. Until then, as long as there is no bleeding (which can occur in some cases), no special precautions are necessary.

I came home from my 20 week rob anatomy ultrasound today, I brought home a cd with all of my pictures on it and stumbled across the preliminary report. It says I have anterior low lying placenta, what is this and should I schedule to see my doctor sooner

I came home from my 20 week rob anatomy ultrasound today, I brought home a cd with all of my pictures on it and stumbled across the preliminary report. It says I have anterior low lying placenta, what is this and should I schedule to see my doctor sooner

Relax!: Low-lying placenta at 20 weeks has >80% chance of moving out of the way as the pregnancy advances and the growing uterus expands higher up in your abdomen (placental migration). You do need another sonogram at 28 weeks and some instructions until then: avoid Aspirin and all nsaids (e.g. Motrin, advil, aleve) and only take regular tylenol (acetaminophen) for aches/pains; nothing per vaginam; no heavy lifting/sex. ...Read more
