Write a brief answer for the question given.
Explain the process of signal transmission and muscle contraction.
The nervous system sends a signal to the muscle, the message is carried by a. The signal travels as an action potential and reaches the point where the neuron connects with the muscle fibre called the. At this location, the neuron releases a chemical messenger known as. This chemical binds to receptors on the muscle fibre membrane and initiates a chemical reaction inside the cell. As a result, special proteins present in the muscle fibres calledrearrange themselves, causing the muscle cell to shorten and produce movement.
