2. Calcification - Wikipedia

   en.wikipedia.org/wiki/Calcification

   One of the principal causes of arterial stiffening with age is vascular calcification. Vascular calcification is the deposition of mineral in the form of calcium phosphate salts in the smooth muscle-rich medial layer of large arteries including the aorta. DNA damage, especially oxidative DNA damage, causes accelerated vascular calcification. [11]

3. T-tubule - Wikipedia

   en.wikipedia.org/wiki/T-tubule

   T-tubules (transverse tubules) are extensions of the cell membrane that penetrate into the center of skeletal and cardiac muscle cells.With membranes that contain large concentrations of ion channels, transporters, and pumps, T-tubules permit rapid transmission of the action potential into the cell, and also play an important role in regulating cellular calcium concentration.

4. Cardiac muscle - Wikipedia

   en.wikipedia.org/wiki/Cardiac_muscle

   Cardiac muscle (also called heart muscle or myocardium) is one of three types of vertebrate muscle tissues, the others being skeletal muscle and smooth muscle. It is an involuntary, striated muscle that constitutes the main tissue of the wall of the heart .

6. Cardiac conduction system - Wikipedia

   en.wikipedia.org/wiki/Cardiac_conduction_system

   Cardiac muscle has some similarities to neurons and skeletal muscle, as well as important unique properties. Like a neuron, a given myocardial cell has a negative membrane potential when at rest. Stimulation above a threshold value induces the opening of voltage-gated ion channels and a flood of cations into the cell.

7. 8 Common Cardiovascular Diseases for Men & How to Prevent Them

   Dilated cardiomyopathy is when the muscle walls of your heart become stretched and can’t pump blood properly. It can be caused by inherited genes, chronic conditions, and unhealthy lifestyle habits.

8. Myocardial contractility - Wikipedia

   en.wikipedia.org/wiki/Myocardial_contractility

   Within an in vivo intact heart, the action/response of the sympathetic nervous system is driven by precisely timed releases of a catecholamine, which is a process that determines the concentration of calcium ions in the cytosol of cardiac muscle cells.

9. Sarcoplasmic reticulum - Wikipedia

   en.wikipedia.org/wiki/Sarcoplasmic_reticulum

   This shape change causes the cytosolic side of the pump to open, allowing the two Ca 2+ to enter. The cytosolic side of the pump then closes and the sarcoplasmic reticulum side opens, releasing the Ca 2+ into the SR. [6] A protein found in cardiac muscle, called phospholamban (PLB) has been shown to prevent SERCA from working. It does this by ...
