What is the area of a chromosome pair that attatches to a fiber stretching across the cell during cell division?
centromere
The primary function of the myocardial working cell include a automaticit b regeneration contraction and relaxation impulse propagation?
CONTRACTION
Action potentials pass from one myocardial cell to another through areas of low electrical resistance called?
gap junctions
What does myocardial cell injury mean?
Myo means muscle and Cardial relates to heart. My educated guess would be that it is a damage in one of the cells in your heart muscle.
Does isotonic soultion cause a cell to shrink?
No. An isotonic solution would not cause a cell to shrink, because the concentration of water in the solution and inside the cell is the same. A hypertonic solution would cause a cell to shrink.
What is the thin filament of the myocardial cell?
Actin
Can heavy coughing cause an uncomplicated myocardial infarction?
No
What are the two cell populations in the body that do not undergo cell division?
Neurones in the CNS and cardiac/myocardial cells.
What will partial obstruction of coronary artery cause?

What ion is released within the myocardial cell with the depolarization and acts on the contractile proteins causing the cell to contract?
myosin?
How does stretching force work?
cause it does
Can a clot in the coronary artery cause a myocardial infarction?
Yes, a clot in the coronary artery can cause a myocardial infarction or a heart attack. Most heart attacks are caused by blood clots that come loose from the walls of the arteries.
Cause of vomiting in a case of myocardial infarction?
Its due to increase surge of catecholeamines cause by sympethetic nervous system....
Does stretching every couple of hours cause arthritis?
No the cause of arthritis is not clearly understood but stretching would be helpful if anything to keeping the joints free.
Why does pericarditis cause a reduction in cardiac output?
because the force of myocardial contraction weakens
The giant protein titin maintains the organizations of the?
The giant protein titin is a major player in myocardial mechanics, signaling, and disease. It maintains the organization of the A-B of a sarcomere assisting in muscle stretching.
