All types of muscle (cardiac, smooth, and skeletal) share the same four properties.
Excitability: Stimulation of myocytes from an electrochemical standpoint at the nerve-muscle junction in order to depolarize and allow contractions to occurs. (So the muscle can do it's job as a lever!)
Contractility: Once a muscle cell is excited (nervous stimulation above) it creates a change in ionic flow and protein binding to allow contraction from many myocytes. (All or nothing rule!)
Extensibility: This is their capacity to lengthen. Up to 3 times their contracted length before deformation or rupture occurs.
Elasticity: The ability for a muscle to recoil, or return, back to its resting length with resting tonus. A muscle with "slack" after a movement with no tension (tone) is unable to generate force.
