A Muscle Contraction Is Triggered When an Action Potential Travels Along the Nerves to the Muscles. Muscle contraction begins when the nervous system generates a signal. The signal, an impulse called an action potential, travels through a type of nerve cell called a motor neuron.
        
             
        
        
        
The idea it can describe is that it is the transfer of information from one neuron to another.
<h3>Transfer of information </h3>
The nervous system is part of the body systems that helps in the transfer of information from nerve to nerve and from nerve to muscle tissues.
The presynaptic nerve is the nerve that sends the information that is to be conveyed in form of action potential impulses.
The impulses led to the release of neurotransmitters from the terminal of the presynaptic nerve to the synapse. This binds to the receptor if the postsynaptic cell which receives the message.

Answer:
Metaphase is a stage in the cell cycle where all the genetic material is condensing into chromosomes. These chromosomes then become visible. During this stage, the nucleus disappears and the chromosomes appear in the cytoplasm of the cell
