4
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
• 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

• 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

• Epimysium - surrounding each muscle closely
• Perimysium - divides the muscle into fascicles
• around each bundle of muscle fibers
• Endomysium - surrounding each muscle fiber
