There are four main characteristics of muscle tissue.
1. Contractility, which is the ability to shorten forcefully
2. Excitability, which is the capacity of muscle to repsond to stimulus.
3. Extensibility, which is the ability to stretch muscle tissue beyond normal resting length and still be able to contract.
4. Elasticity, which is the ability of muslce to recoil to ist original resting length post stretching. This is why patients develop rigor mortis, after they die, because the muscle naturally want to recoil back to their original lengths.
