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 heater functions with the help of a healthy cooling system and the heater controls inside the passenger compartment. Depending on the symptoms, there are various reasons why your heater might not be working. Engine temperature gauge is normal, but I have no heat! First, check your engineâs coolant level. If the coolant level is low, air may become trapped in the heater core. Smooth coolant flow through the heater core is critical for heat output. While the vehicle is running, heat produced by the engine is absorbed by the engineâs coolant and flows through the heater core. The heater core is a little radiator usually located behind the dashboard in the passenger compartmentâit is the heat source for your vehicleâs climate control system.
