4. Muscle Tissue Contractility Excitability Extensibility Elasticity
9/10/2019
Muscle Tissue
Contractility
ability to shorten
Excitability
receive and respond to a stimulus
Extensibility
ability to increase in length
Elasticity
return to resting form after being contracted

5. Purposes Movement Support Heat production
9/10/2019
Purposes
Movement
working together with nervous and connective tissue as well as bone
Support
maintain an upright posture as well as strengthen the frame
Heat production
75% of energy from contraction is lost as heat

6. Connective Tissue Coverings
9/10/2019
Connective Tissue Coverings
Fascia - broad band of collagen-based connective tissue
Tendons - connective tissue connecting muscle to bone
connects in the periosteum for strength
Aponeurosis - fascia of one muscle attaching to that of another muscle

7. Connective Tissue Coverings
9/10/2019
Connective Tissue Coverings
Epimysium - surrounding each muscle closely
Perimysium - divides the muscle into fascicles
around each bundle of muscle fibers
Endomysium - surrounding each muscle fiber
