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.
A North American block heater cord and plug. A block heater warms an engine to increase the chances that the engine will start as well as warm up the vehicle faster than it normally would in extremely cold weather.The most common type is an electric heating element in the cylinder block, connected through a power cord often routed through the vehicle's grille.The block heater may replace one of the engine's core plugs.In this fashion, the heater element is immersed in the engine's coolant, which then keeps most of the engine warm. There is no pump with this type of heater. They may also be installed in line with one of the radiator or heater hoses.Block heaters that run on the vehicle's own gasoline or diesel fuel supply are also available; these do not require an external power source.here is no pump with this type of heater.
