Questions and Answers

What is the role of acetylcholine in the neuromuscular junction?

  • It promotes the breakdown of ATP to provide energy for muscle contraction
  • It inhibits the release of calcium ions from the sarcoplasmic reticulum
  • It prevents the binding of myosin to actin filaments
  • It acts as a neurotransmitter that stimulates muscle contraction (correct)
  • What is the function of the sarcoplasmic reticulum in muscle cells?

  • It synthesizes ATP for energy production
  • It stores and releases calcium ions for muscle contraction (correct)
  • It controls the production of acetylcholine for neuromuscular transmission
  • It regulates the production of myosin and actin filaments
  • What is the primary function of the motor neuron in muscle physiology?

  • To transmit signals from the central nervous system to muscle fibers (correct)
  • To generate ATP for energy production in muscle cells
  • To regulate the production of neurotransmitters in muscle cells
  • To store and release calcium ions for muscle contraction
