The region of the brainstem that plays a role in arousing you to a state of alertness would be the reticular formation. It is responsible in regulating the sleep cycles and in detecting sensory conditions. It consists of more than 100 neural network that are for various functions.
The basic structure of a muscle fiber is comprised of actin and myosin protein chains that straddle each other in a fusiform arrangement. The actin and myosin arrays interlock and move past each other to cause contraction of the muscle. They then move back to their initial positions in relaxation. This gives muscles their elasticity and distensibility. The muscle fibers are bundled, in their 10s to 100s up into myofibrils around an endomysium. Many myofibrils are also bound up in a perimysium to form a muscle fiber.
