• The study of the muscular system

• Kinesiology
• Anatomy
• Myology
• Physiology

• To chemical signals, stretch, and electrical changes across the   plasma membrane

• Excitability

• Conductivity

• contractility

• extensibility

• elasticity

• Local electrical change triggers a wave of excitation that travels    along the muscle fiber

• extensiability

• contractility

• conductivity

• Excitability

• elasticity

• Shortens when stimulated

• • Contractility

• extensiability

• elasticity

• conductivity

• Capable of being stretched between contractions

• extensibility

• elasticity

• conductivity

• excitaability

• Returns to its original rest length after being stretched

• elasticity

• extensibility

• contractility

• conductivity

• excitability

• voluntary, striated muscle usually attached to bones

• alternating light and dark transverse bands

  • Results from arrangement of internal contractile proteins

• is a muscle fiber (myofiber)—as long as 30 cm

• muscle cell
• myocyte
• sarcomere
• myofiber

• connective tissue around muscle cell

• epimysium
• fascia
• endomysium
• perimysium
