What does myocardial cell injury mean?
Myocardial cell injury refers to damage or harm to the cells that make up the heart muscle (myocardium). This can be caused by various factors such as lack of oxygen, toxins, inflammation, or physical trauma. Myocardial cell injury can lead to heart conditions such as heart attacks or heart failure.
What is the area of a chromosome pair that attatches to a fiber stretching across the cell during cell division?
The area of a chromosome pair that attaches to a fiber stretching across the cell during cell division is called the centromere. The centromere plays a crucial role in ensuring equal distribution of genetic material to daughter cells during cell division, as it serves as the attachment point for spindle fibers that assist in separating the chromosomes.
Myocardial cells can generate action potentials spontaneously because they have?
Myocardial cells can generate action potentials spontaneously due to the presence of funny (If) channels that allow for a slow influx of sodium ions, as well as T-type calcium channels that contribute to the depolarization phase of the action potential. These channels, coupled with the unique organization of ion channels in the myocardial cell membrane, enable automaticity in these cells.
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 can cause a cell the divide out of control?
Abnormalities in genes that control cell growth and division, such as mutations, can cause a cell to divide out of control. This uncontrolled division can lead to the formation of a tumor.
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?
myocardial infraction
What describes when the myocardial cells recovers electrically?
The process by which myocardial cells recover electrically after depolarization is called repolarization. During repolarization, the cell's membrane potential returns to its resting state as potassium ions exit the cell. This phase prepares the myocardial cells for the next electrical impulse.
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....
Why does pericarditis cause a reduction in cardiac output?
because the force of myocardial contraction weakens
What does myocardial cell injury mean?
Myocardial cell injury refers to damage or harm to the cells that make up the heart muscle (myocardium). This can be caused by various factors such as lack of oxygen, toxins, inflammation, or physical trauma. Myocardial cell injury can lead to heart conditions such as heart attacks or heart failure.
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.
What is the thin filament of the myocardial cell?
The thin filament of a myocardial cell is composed primarily of actin, tropomyosin, and troponin proteins. These proteins play a crucial role in regulating the contraction and relaxation of the heart muscle by interacting with the thick filament during the process of muscle contraction.
