Define PSSM.

Explanation:
PSSM refers to a muscular disorder in horses in which an abnormal amount of polysaccharide, including glycogen, accumulates inside muscle fibers. This excessive storage makes the muscles prone to exertional rhabdomyolysis, commonly seen as tying-up, muscle tremors, stiffness, and gait abnormalities after exercise. This description matches the established term Polysaccharide Storage Myopathy, which is the standard name for the condition. The other phrases do not describe this recognized condition and would not account for the characteristic muscle problems seen with PSSM.
