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.

Remove coolant recovery tank. 2  Remove heater core hoses. 3  Place a clean pan under the vehicle to catch any coolant spillage. 4  Plug the hoses. 5  Allow coolant in the core to drain into the pan.
