Quivering or spontaneous muscle contractions especially of the heart is called?
fibrillation
What Muscle cause contractions of the heart?
the lungs and the legs contract the heart for regular pulse that murmurs
Potassium poisoning causes and symptoms?
Arrhthmyia of the heart, problems with smooth and skeletal muscle contractions; hyperkalemia can even stop the heart muscle.
Why is it important that summation not occur in heart muscle?
Basic muscle summation -an increase in the frequency with which a muscle is stimulated increases the strength of contraction. With increased stimuli to the heart if summation occurred the contractions would keep increasing.
What are the effects of cardiotonics and anticoagulant merdication?
cardiotonics increase the strenght of the muscle contractions that pump blood from the heart.
What the functions of cardiac muscle?
the cardiac muscle is your heart. you tell me. ever heard of cardiac arrest? its also called a heart attack.
What is the function of the peacemaker?
a small group of cardiac muscle cells that "set the pace" for the heart as a whole and they begin each contractions.
Can you die from electric shock?
Yes. If strong enough, the electric current can cause intense muscle contractions. The muscle contractions can fatigue the muscle, depleting it of nutrients and electrolytes. When that happens, the muscle is incapable of functioning, and if the muscle happens to be your heart, you die. CPR can be helpful because it brings nutrients back to the heart muscle and provides sufficient blood flow to keep the individual alive until the heart can start again. In general, the effects of electric shock are immediate. If the voltage and current are high enough, an electric shock can burn tissue causing permanent damage.
During which 2 periods of the cardiac cycle do the heart muscle fibers exhibit isometric contractions?
Isovolumetric contraction and Isovolumetric Relaxation
What is the layer of the heart that produces its contractions?
The contractions start from a node in the myocardiumcalled the SA node (sino-atrial node), which produces the stimulatory signals in a rhythmic mode. As the stimulatory signals move throughout the myocardial muscle, it contracts.
What happens when summation occurs in cardiac muscle?
Basic muscle summation -an increase in the frequency with which a muscle is stimulated increases the strength of contraction. With increased stimuli to the heart if summation occurred the contractions would keep increasing.
What nervous system controls the skeletal muscle contractions?
The central nervous system supplies the body and muscle contraction. Striated muscle (skeletal muscle) contract voluntary with exception of the heart which is striated involuntary smooth muscle.
