What else can I help you with?
What is the muscle that normally exhibits arrhythmic contractions?
The heart muscle is the muscle that normally exhibits arrhythmic contractions. These contractions are controlled by the heart's internal pacemaker system, which generates electrical signals to regulate the heart rate and rhythm.
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.
What is the difference between myogenic and neurogenic muscle?
Myogenic muscle contractions are initiated by the muscle cells themselves without external neural stimulation, such as in the heart muscle. Neurogenic muscle contractions require neural input to initiate and control muscle activity, such as in skeletal muscles controlled by the somatic nervous system.
What are the effects of cardiotonics and anticoagulant merdication?
cardiotonics increase the strenght of the muscle contractions that pump blood from the heart.
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 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 are digitalis drugs?
Digitalis drugs are a group of medications derived from the foxglove plant that are used to treat heart conditions like heart failure and irregular heart rhythms. They work by increasing the strength and efficiency of the heart's contractions. Digitalis drugs are sometimes called cardiac glycosides.
Which tissue has intercalated discs?
Cardiac muscle tissue has intercalated discs, which are specialized structures that help with communication and coordination of muscle contractions in the heart.
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.
Where does ventricular contractions start?
Ventricular contractions start in the Purkinje fibers, which are specialized muscle fibers located in the walls of the ventricles of the heart. These fibers rapidly conduct the electrical signals to synchronize the contraction of the ventricles and pump blood out of the heart.
