It was this accumulation of grievances that led to the burst of the Mongol attack on Islamdom from 1200 that culminated in the sack and slaughter at Baghdad in 1258 under Hulagu Khan who was egged on to this path by his Nestorian Persian Christian wife.
Type IIx are best known as fast-twitch muscle fibers. These are the muscle fibers primarily responsible for fast, explosive movements like sprinting. However, they lack the endurance-boosting ability of slow-twitch fibers and can only be used for short periods of time.Type IIa are what we call intermediate fibers. These are a blend between fast-and slow-twitch fibers.hese are the muscle fibers primarily responsible for fast, explosive movements like sprinting.

It is through this connective tissue that the force generated by the individual cells is transmitted to the bone. A group of muscle cells are bundled together by collagen to form a fascicle. Since muscle cells are elongated and cylindrical, each muscle cell is usually called a muscle fiber.In skeletal muscle, the muscle fibers are very large, multinucleated, and up to several millimeters in length.he contraction of a muscle fiber is triggered by an action potential conducting over plasma membrane of the muscle fiber. The action potential conducts from the surface of the muscle fiber into the interior via transverse tubules (T tubules).
