What is the medical term meaning the sac that contains the heart?

User Avatar
The pericardium is a double walled sac that encloses the heart, and the proximal ends of the aorta, vena cava, and the pulmonary artery. The visceral layer is next to the heart, then a bit of fluid, and the parietal layer is outermost. In trauma, it can become filled with blood and impinge on the heart. Peri - means around, and - cardium means heart.

Can different music effect your heart rate and does it change by gender?

User Avatar
In a study out of Oxford University, Dr. P. Sleight and his investigators found that listening to music initially effects change of heart rate that is directly proportional to the tempo of the music and possibly to the complexity of the rhythm. They also found that the style of the music or the music preference of a subject appears less important than the tempo of the music, and that music with a slower rhythm and some short pauses or breaks in the music induces calm in the listener. Effect of Music on Heart Rate Obviously, music that has a faster tempo and louder will generally make a person's heart rate and blood pressure spike, probably because it releases adrenaline, similar to a stressful situation. Another ... This is according to Medscape Medical News The researchers found that compared with baseline, the subjects' mean flow-mediated dilation: Decreased 6% after listening to enjoyable music (P = .0002). Increased 26% after listening to anxiety-provoking music (P = .005). Increased 19% after watching a humorous video (P = .08). Decreased 11% after listening to a relaxation tape (NS). In your Heart, there is a sensor that receives pulses that dictate how fast the heart beats. Heavy and loud music, especially with a strong beat, can interfere with that sensor, causing the heart to beat in time to the music. Here is more from Wiki s contributors: I am doing a science fair project on this topic. My project actually includes the effect of music on the heart rate and blood pressure of a person. I have done some research and it really depends on what kind of music it is. For example, Heavy Metal and Rap REALLY gets the heart rate and blood pressure going, while Classical music lowers it. I am also doing a science fair project and I found that rock music really gets the heart rate going and the classical music takes the heart rate down by a lot. I put together a few years back, you will find answers as well as studies. Check the related link below. p.s this site is full of it ! they say nothing true!

Do girls have bigger hearts than men?

User Avatar
No--on average. Because they're smaller, their hearts will be smaller in turn. Think about it...you can't be the size of a housecat and have a pumper equivalent in size to a bull! Similarly it doesn't work the other way around either.

Can Straterra cause a sleep problem?

User Avatar
According to Eli Lilly's Strattera Web site, "problems sleeping" are a common side effect. I have found it really hard to fall asleep no matter when I take it. I have tried everything from eating and taking it at different times, nothing helps i am fairly new to all the meds, but have recently been dealing w/ my step-son taking Straterra. He is only 12 and it seems to make him want to sleep constantly. But i dont believe that it is given to him at the same time everyday and he also travels between parents home constantly which i dont believe helps. When I first started taking Strattera, I definitely had sleep issues. Though I can always fall asleep, I would have fitful sleep. I would dream vividly, but find myself unable to really exit the dream to wakefulness. And then at some point in the night, I would wake totally, and be unable to sleep for a while. At this point, I would worry about things. I would finally fall asleep and sleep fine for the rest of the night. I've been on Strattera now for nearly 8 months and I have found the fitful sleep to be much, much less. Occasionally I'll have those weird, vivid dreams, but not nearly as often as I did at the beginning. And while I still usually wake up, I have learned to ignore my worries, knowing that when I wake in the morning, those issues won't be there. But it has taken time to get to this point. I do find Strattera makes me tired during the day, but I will try what the other person has mentioned, about being strict on when the dose is given. I'm really bad about that, and I think I can point to the times when I get super tired during the day having to do with failing to dose within a certain window. For me; yes. I've been on Strattera 120 mg for 3 months, and my sleeping problems still get worse. Some nights I don't sleep at all. It makes me very frustrated. But the funny thing is; the pills are making me wide awake in the daytime. I feel that I don't need much sleep. But, of course, I do. So from time to time I have to use Xanor - I belive you call it Xanax in the US - to get some sleep. I'm now thinking about cuting down on my dosage. It's a shame really, because it works for my ADD. My son who is 12, has been on Strattera for 4 months now. For the first two he was fine,his concentration great, and loving all its effects. He took it in the morning at 7 am before school, but in the last several weeks, he has been very sleepy in the morning, and restless and insomniac at night, waking at 2 or 3 am. His concentration has gone down considerably, he even has aggressive outbursts again. He has taken melatonin before and done well but to take it on a constant basis seems odd for his age. The last two night we have changed the 7 am ritual for 5 pm, and by 9 pm he is falling asleep right away, with nothing additional. He tried biofeedback last week and not even that worked as well as the change of schedule. So who knows, I am still trying. It seems that if he gets poor sleep he´s adhd worsens no matter what dosage he takes. Anybody else doing this? I am 27 yrs old, and have been taking straterra at about 10pm(1-2hrs before bed)with some milk (for my stomach). I also take 3mg of Melatonin 1 hr before bed. I can sleep pretty well (say 4-6hrs soundly, the rest somewhat light). The worst time for me was taking straterra in the morning or afternoon. It makes me tired at first then wired and restless. If you take it after dinner it seems to be the least bothersome. Melatonin really helps and I don't plan on taking it forever.. its a lot better than taking ambian which makes me hungover.. i am 15 years of age and have been on strattera for at least a year and i find it extreamly hard to sleep and only get a maximum of 8 hours with out tosing and turning and continuosly waking up

What is the medical term meaning muscular layer of the heart?

User Avatar
The muscular walls of the heart consist of three major "layers." The bulk of the walls is made up of a layer of cardiac muscle and is called the myocardium. The muscle is enclosed on the outside by the epicardium and on the inside by the endocardium. The heart is also covered completely by a protective sac called the pericardium.

What part of the nervous system is responsible for accelerating the heart rate in an emergency?

User Avatar
The sympathetic nervous system also known as fight or flight or the stress system, will increase heart rate quickly. In an emergency it over rides the medulla oblongata section of the brain stem which is in charge of cardio control.

How do polar heart watches work?

User Avatar
When your heart beats, it releases a tiny electrical charge that goes to the skin. This electrical charge is picked up by a heart watch or monitor, and is used to measure heart rate, and by extension, how many calories your body is burning.

What does 'consent to rate' mean on a workman's comp bill?

User Avatar
Consent to Rate means that the insurance company must have the consent of the insured (i.e. by a signed form) to charge higher than the filed (with the State, if applicable in your state) rate. **** More information** To elaborate on the above answer, Florida is a good example of a state that allows Consent to Rate - these forms must be signed prior to binding. the resons for consent to rate would be Unable to Obatin Coverage at the filed rate, Unfavorable loss experience, unusual hazards or claims activity and such.

Why is systems auricle medicine related to the great changes of 21st century?

User Avatar
Auricular Medicine is a scientific medical system which can diagnose and treat many different diseases of the body and the mind solely through the ears. After more than 40 years of research and practice. Dr. Li-Chun Huang, an internationally renown physician, and Dr. William S. Huang founded this unique art of healing. This practice can as of date, diagnose and assist in the healing of over 700 ailments. Massive positives of this method are; -Low cost, and high efficiency -No need for costly, and hard to procure medical instruments -Very little risk of malpractice -No injections, medications, drugs etc These changes have helped shift much scientific thought awayf ROM the traditional "western" healing methods, and now much research is being put into simpler, cheaper, and more readily available treatment methods.
Asked in Heart

What heart chamber receives blood from pulmonary circulation?

User Avatar
The circulatory system is composed of the heart and blood vessels, including arteries, veins, and capillaries. Our bodies actually have two circulatory systems: The pulmonary circulation is a short loop from the heart to the lungs and back again, and the systemic circulation (the system we usually think of as our circulatory system) sends blood from the heart to all the other parts of our bodies and back again.

Asked in Nervous System, Heart, Nerves

What would happen if the heart did not have nerve tissue?

User Avatar
The muscles in the heart respond to an electrical stimulus to contract (beat). If there were no nerve tissue, the heart would not beat and a person would cease (or fail) to exist. Failure of the nerve stimuli, if nerve tissue is there (but for whatever reason there is a malfunction of the signal getting to where it needs to be), results in a condition called "Heart Block" and that can necessitate the implantation of a Pacemaker to produce the missing electrical stimulus constantly or intermittently as needed.
