the site where a motor neuron excites a skeletal muscle fiber is called the neuromuscular junction. this activity will test your understanding of the sequence of events that occur at the neuromuscular junction.

The correct order of occurrence from left to right of the events that occur at the neuromuscular junction after the action potential reaches the axon terminal is as follows:

  • Ca²⁺ enters the axon terminal.
  • Synaptic vesicles release ACh.
  • ACh binds to ACh receptors.
  • Ligand-gated cation channels open.
  • Na+ enters and K⁺ exits.
  • Membrane potential is less negative

What is the neuromuscular junction?

The neuromuscular junction is described as a synaptic connection between the terminal end of a motor nerve and a muscle. It is the site for the transmission of action potential from the nerve to the muscle.

The neuromuscular junction  has three basic components which include

  • presynaptic motor nerve terminal,
  • synaptic space (synaptic cleft), and
  • the postsynaptic surface of the skeletal muscle fiber.
