excitability : muscle cells are sensitive to stimuli From nearous
or chemical messages chomies

Contractivity : ability to shorten +
generate face when stimulated
↳ allows muscle to
pull on bone/structures to create movement
Extensibility : muscle tissue has different degree of
flexibility

↳
helps body adapt to many positions + moveners

Elasticity Once: stretched, tissue wants to return to its
original length

smoom , coordinated movement
