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 radiator is linked to the engine by rubber hoses, and has a top and bottom tank connected by a core a bank of many fine tubes. The tubes pass through holes in a stack of thin sheet-metal fins, so that the core has a very large surface area and can lose heat rapidly to the cooler air passing through it.
