Action potentials are a fundamental aspect of nervous system function in many animals, including humans, but the specific mechanisms and characteristics of action potentials can vary between species.

Action potentials trigger the release of neurotransmitters, which bind to receptors on the muscle cell surface, initiating a series of chemical reactions that lead to muscle contraction.

While action potentials are primarily associated with nerve fibers, similar electrical impulses can also occur in muscle cells and other types of cells.

  • Resting potential: The nerve fiber maintains a stable negative charge.
  • Action potentials are generated when electrical impulses travel along the length of a nerve fiber, resulting in a rapid depolarization of the cell membrane. This process allows the nerve fiber to transmit signals to the muscles, instructing them to contract. The sequence of events involved in an action potential includes:
