the stable attachment point
usually more proximal and larger surface attachment.
What are the four characteristics of muscle tissue and their function?
Elasticity-muscle returns to normal vestina length after being stretched or contracted.
excitability-ability of muscle tissue to receive and respond to stimulus.
extensibility-ability of muscle tissue to be stretched.
contractability- ability to become short and thick.
