A derecho (/dÉËreÉªtÊoÊ/, from Spanish: derecho [deËÉ¾etÊo], straight) is a widespread, long-lived, straight-line wind storm that is associated with a land-based, fast-moving group of severe thunderstorms. Derechos can cause hurricane-force winds, tornadoes, heavy rains, and flash floods.
In human anatomy, a hamstring is one of the three posterior thigh muscles in between the hip and the knee. In quadrupeds, the hamstring is the single large tendon found behind the knee or comparable area.
Hamstring tendinitis is a disorder involving tissue inflammation and damage to one or more of the hamstring tendons. Hamstring tendinosis is a degenerative condition of the tissue involving little if any inflammation. The three hamstring muscles on the back part of the thigh have tendinosis insertions on the ishial tuberosity (sit bones) and the back of the lower knee (tibia and fibula).
