The cells of skeletal muscle are referred to as muscle fibers. Each fiber is surrounded by its own basement membrane, which is continuous with the endomysium. The fibers are long, tapering cells that contain many nuclei (i.e., multinucleated).he cells of skeletal muscle are referred to as muscle fibers.

When you turn on your carâs heater, the hot coolant flows from the engine to the heater core, which is located inside the carâs dash. A fan (the same one used by the air conditioner) blows air through the heater core, with the heated air then passing through the carâs vents and warming the interior. The Controls.
Enter the cooling system. The cooling system is used to keep the engine from overheating. It does this by keeping the temperature at a constant so it runs more efficiently. The cooling system uses coolant to do this. Coolant is a 50/50 mixture of water and antifreeze. When you start your engine, a water pump circulates the coolant through the engine and radiator. Once the engine has reached a certain temperature, a thermostat opens to control the flow of coolant through the radiator.
