1.2 The Muscular System

• Outline the general characteristics common to muscle tissue

  • contractility

  • extensibility

  • elasticity

  • atrophy

  • hypertrophy

  • controlled by nerve stimuli 

  • fed by capillaries

• Distinguish between the different types of muscle

  • smooth

  • cardiac

  • skeletal (voluntary)

• Annotate the structure of a skeletal muscle

  • epimysium

  • perimysium

  • endomysium

  • muscle fibre
