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.
The core is basically a small radiator. Most older cars used a heater valve to shut off the flow of hot coolant when heat was not desired. Most modern era cars circulate hot coolant all the time and airflow is diverted by small doors in the A/C/heater ductwork. There was a gasoline fueled heater option for the old air cooled VW buses.
