Muscle tissue has four main properties: Excitability (ability to respond to stimuli) Contractibility (ability to contract) Extensibility (ability to be stretched without tearing) Elasticity (ability to return to its normal shape).
Excitability
effectors
Excitability = the ability to receive and respond to a stimulus Contractility = the ability to shorten Extensibility = the ability to be stretched Elasticity = the ability to resume normal length after contraction or having been stretched.

Muscle cells are irritable and respond to stimuli. Muscle twitch is defined as contraction and relaxation in the muscle cell. The stimulus needs to be above a certain threshold for the muscle fibres to react. The more the stimulus, the greater the strength of the contraction.
