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

What area of the brain has the greatest effect on visceral functions (e.g. heart rate and hormone production)?
Hormones: Please go online to Yahoo Images or something similar and look for images of the Pituitary Gland. There is usually a small comment with the images. Fell free to contact me again if there are things on the web you don't fully understand. You can of course also discuss these items with your doctor. ...Read more
Mri-cardiac morphology w/0 contrast and an mra -chest the report only mentions the aorta and its size. I have multi valve and function issues. Should the report discuss function, chamber sizes etc?
No particular size: Number of vaginal deliveries is a risk factor for pelvic organ prolapse. For example, a woman with 6 natural births will be more at risk for prolapse than a woman without any children. The relationship between baby weight and prolapse is still controversial. ...Read moreSee 1 more doctor answer

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
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
Vascular loops in close proximity to cisternal sgmnts of bilteral 7th and 8th cranial nerves without dformng contours. What does this mean?
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. Do not let anybody inject you with glyceraldehyde either please. Stay sharp lad...you can always redo the MRI down the road and see if it changes. A good GOOD neurologist can help you. ...Read more
Fm 49, all docs say trans-vaginal us can not cause prolapse to pelvic organs. What if procedure done roughly on narrow introitus with weak structure?
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 moreSee 1 more doctor answer

Is gray's anatomy the best reference book for me to learn about my body more in depth ? What's the physiology equivalent ?
Gray's anatomy: Was first published in 1858! our understanding of anatomy hasn't changed that much over the centuries whereas our knowledge of physiology has progressed very rapidly. As such i'm not aware of a "classic" physiology textbook, and i would simply recommend checking out user reviews on amazon or b&n. As for anatomy, i found netter's to be more approachable than gray's. ...Read more

As a dental surgery student should I study anatomy and physiology or it is not essential for my major ?!
Would i need to take college human anatomy and physiology to become a physical therapist? Even if the programs doesn't require it.
Absolutely: These two areas are so important to be a great and competent pt expert. It is actually fun. ...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. Best Wishes ...Read more
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 moreSee 1 more doctor answer
Yes: Yes, thc crosses the placenta. When pregnant women smoke marijuana, there is an increased risk for premature birth and lower birth weight, length and head circumference. Babies that are born prematurely or with low birth weight have higher rates of infant deaths, learning problems or other disabilities. ...Read more
