Presentation Transcript
functions of muscle

Aid in movement

  • Provide and maintain posture
  • Protect internal organs
  • Provide movement of blood, food and waste products throughout the body
  • Open and close body openings
  • Produces heat
Functions of Muscle
muscle stimulation

Electrically

  • Mechanically
  • chemically
Muscle stimulation
vocabulary

Irritability or excitability: ability to respond to a stimulus

  • Contractility: ability to shorten
  • Extensibility: ability to stretch and lengthen
  • Elasticity: ability to recoil to its resting length
Vocabulary
skeletal muscle

Makes up 40 % of body weight

  • Increase in size and weight with exercise
  • Named according to:
    • Location
    • Related bones
    • Shape
    • Action
    • size
  • Looks striated under microscope
  • Tendons attach muscle to bone
Skeletal Muscle
units of muscle fibers

Sarcomere:

  • Causes contraction
  • Made up of actin and mysosin
Units of Muscle Fibers
3 parts of skeletal muscle

Origin: attached to the less movable part of bone

  • Insertion: attached to the more movable part of the bone
  • Body: middle part of the muscle
3 parts of Skeletal muscle

Flexion = decreasing joint angle

  • Extension = increasing joint angle
  • Abduction = movement away from midline
  • Adduction = movement towards the midline
  • Pronation = turning palms down
  • Supination = turning palms up
visceral muscle

Lines organs

  • Makes up walls of blood vessels
  • In the digestive system
  • Smooth – has no striations
  • Contracts when stimulated
  • Controlled by the autonomic nervous system
Visceral Muscle
cardiac muscle

Only in the heart

  • Striated muscle
  • Involuntary control
Cardiac Muscle
