The ligament on the outside of the ankle (lateral ligament) is made up of three separate bands: one at the front (anterior talo-fibular ligament), one in the middle (calcaneo-fibular ligament) and one at the back (posterior talo-fibular ligament). The front and middle bands are the ligaments injured in a sprain.

Understanding Load-sensing Control. When things go awry with a piece of hydraulic equipment, the maintenance technician is usually the first on the scene. For the technicianâs troubleshooting efforts to be effective, he or she must understand how the equipment operates. One type of hydraulic control system in widespread use, but not well understood, is load-sensing control. Load-sensing describes a type of variable pump control used in open circuits. It is also termed this because the load-induced pressure downstream of an orifice is sensed and pump flow is adjusted to maintain a constant pressure drop (and therefore flow) across the orifice.
