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.
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.
Do muscle contractions cause menstrual cramps?
No, not quite.Prostaglandins are produced which cause the uterine contractions to push out menstrual flow, in a healthy woman this should not be painful. It's when the prostagladins are overproduced that menstrual cramps occur as these cause blood vessels to contract so cut off oxygen to the muscle.
What and where are sarcomeres?
These are found in muscle cells. The action causes contractions. They cause a sliding or shortening movement.
Is sodium healthy for dogs?
Sodium is a vital nutrient for dogs (and all other mammals, incidentally, including humans). It is involved in maintaining normal cellular water balance as well as muscle contractions, nerve impulse conductions and heart muscle contractions. However, too much sodium in a dog with less than ideal kidneys can cause problems ranging from heart failure to water retention.
What the functions of cardiac muscle?
