What is the sudden and immediate cessation of cardiac contractions?
I'm not sure what kind it is but its called an arrhythmia.
How many muscles in the heart?
Your heart is a cardiac muscle which means it never stops and works on its own.
Can the heart contain smooth muscle?
No, they are not. Cardiac muscle is a type of involuntary striated muscle found only in the walls of the heart.
This is a specialized muscle that, while similar in some fundamental ways to smooth muscle and skeletal muscle, has a unique structure and with an ability not possessed by muscle tissue elsewhere in the body. Cardiac muscle, like other muscles, can contract, but some of the cells have the ability to generate an action potential, known as cardiac muscle automaticity. Meaning that some of the cells can beat on their own without any nerve stimulation.

What is the difference between the muscles of heart and the muscles of leg?
The structure of the leg muscle is similar to the heart muscle in their makeup. There are studies that have shown that leg muscles can be injected into the heart.

lungs, for one.
heart, lungs, and tongue.
Which layer of the heart wall contracts and is composed primarily of cardiac muscle tissue?
Yes. For future refference myo as a prefix generally means it has something to do with muscle contraction. Cardi odviously means is has something to do with the heart.
Why does the heart muscle need oxygenated blood?
the heart is a muscle, and every muscle needs blood because the blood caries oxygen to the cells of that muscle which is then converted into energy and this is what makes our bodies work. your heart however is a special muscle that pumps your blood to all of the muscles in your body.

What type of muscle is found only in the walls of the heart?
Cardiac muscle forms the muscular wall of the heart. Cardiac muscle is involuntary muscle.
What three types of tissue make up your heart?
epicardium = the top layer that is actually 2 layers
myocardium= the middle layer also the muscle
endcardium= the inner most layer that seperates blood from muscle
There are a number of different phrases and names that have the acronym AVM. For instance, arteriovenous malformation, a medical issue in which arteries and veins have problems connecting, has the acronym AVM. Automated vehicle monitoring, automated valuation model, and application value management are also phrases that could be abbreviated with the acronym AVM.
What are the three types of microphone?
o good overview is at http://www.soundonsound.com/sos/1995_articles/jun95/microphones.html here the broken down list: dynamic microphones: mesh ball on a stick, used in live sound-- inexpensive and hard-wearing capacitor microphones: more sensitive than the dynamic, picks up high-frequency sound, needs electric source to receive electrical charge electret microphones: similar principle as capacitor microphones, except its diaphragm uses an insulating material-- as a result, it has a permanent electrical charge
Why does death of heart muscle cells happen?
Many reasons - but most commonly due to a lack of oxygen secondary to blockage of a coronary artery.
How would the thickened muscles on the left ventricle affect the function of the heart?
If the left ventricle is weak, it causes the volume to back up. The increase volume, over time, will result in ventricular dilation.
What muscles are used for playing basketball?
The precise answer is: •Traipses, calf, biceps, trapezius, anterior deltoids, posterior deltoids, pectorals, hip, and quadriceps are the primary muscles used in volleyball.
There are a variety of muscles used to play volleyball. There are several different types of actions in volleyball that use different musclesin different ways. Serving- If you are serving from the ground (not jumping) then the muscles used are the bicep tricep and shoulder muscles. You also use the muscles in your forearm and wrist as well as some support from the abdomen. If you add a jump (jump serve) then you would include all of the major muscles groups in the lower body, Gluts, Calves, Hamstrings and Quads. Hitting/Spiking/Blocking- You use several different muscles here as well for the arm motions you use the same muscles as you would for serving. Except for here you use the midsection as well. The leg portion uses the major muscle groups Passing/Setting- The power from setting comes from the shoulders wrists and legs- Specifically the calves in the legs. Passing uses the shoulders and the legs specifically the quads. IF this question is asking what muscles are used so I can build up strength in the most important ones then the answer is this- The quads, shoulder muscles, pectorals and the Abdomen are places I would focus on. The higher you can jump the better volleyball player you will be. Most people use weight training and plyometrics to build their lower body.
What body cavity is the aorta in?
The descending aorta is divided into two portions, the thoracic and abdominal, in correspondence with the two great cavities of the trunk in which it is situated.
The descending thoracic aorta is located in posterior mediastinum.
How does music improve brain development?
Yes they do. Recent research in child development shows that classical music stimulates the higher thinking while rap appeals to the reptile brain. A child's brain before they are 4-5 years olds learns information and develops faster than at any age in their life. As the brain develops new synapse more and more is learned. The research compared the brain activity of child and the type of music and it showed that the brain activity with classical music formed new synapse. While working with preschoolers and in classrooms I have always used music with my students. New research shows that music correlates to math thinking and reading skills.
What kind of muscle is responsible for the heart pumping action?
The heart itself is a muscle, however the heart all is made up of different muscles. The muscle knows as the MYOCARDIUM makes up the largest portion of the Heart Wall. The myocardium is made up of the cardiac muscle tissue, which is responsible for the pumping action.
What are the themes Sundiata uses in the poem blink your eyes?
SOME OF THE THEMES IN SUNDIATA ARE LOVE, RESPECT, HONOR, FAMILY, JEALOUSY AND TRADITION
How does atmospheric pressure affect arthritis and muscular aches and pains?
Absolutely.
While those "Professionals" called Doctors swear there is no "scientific evidence" to prove that low pressure affects arthritis, old injuries, migraines, etc., those of us who have these problems know better. I'm pretty much a hermit hibernating in the wintertime because of the lower pressure systems in our area during that time of year.
Migraines are another good example - now as the weather has been changing, and low pressure systems are becoming more prevalent, my migraines have increased in intensity as they always do during this time of year. My other problems (from old injuries, surgeries, etc.) are hurting more as well, as is my arthritis.
Trust your own heart on this one - you wouldn't have asked if you didn't believe there was a connection, and deep down you know that it does affect you, as the rest of us already know it affects us.

What are examples of voluntary and involuntary muscle?
a voluntary muscle is a muscle that move when you tell it to
Muscles in our hands (skeletal muscle) are called voluntary, because these muscles act according to the impulses (orders) given by our conscious brain.
Heart (cardiac muscle) is an example of an involuntary muscle. It works all the time with impulses from our brain stem, which is involuntary.
some more examples of voluntary muscles in our body are, muscles of the chest, neck, abdomen, etc. and those of involuntary muscles are, muscles of the digestive system, smooth muscles etc.
