Excitability: can respond to stimulus; nervous stimulation ? Contractibility: can shorten and thicken ? Extensibility: can stretch ? Elasticity: ability to return to original shape FunctionsofMuscle ? Motion: locomotion (skeletal); movement (cardiac and smooth) ? Maintenanceofposture: opposes gravity (skeletal) ? Stabilizingjoints: light constriction holds muscle tight and joint in place (skeletal) ? Heatproduction: arrectorpilli (smooth) SkeletalMuscle Composition (2+ tissues working together for single function = organ) ? Skeletal muscle fibers ? Blood vessels ? Nerve fibers ?
