A neuromuscular junction is a chemical synapse between the muscle fibre and the motor neuron. It helps the motor neuron to send a signal to the muscle fibre, triggering contraction in the muscle.
One Muscle Fiber has oneneuromuscular junction in most skeletal muscles. A mature neuromuscular junction is innervated by one motor nerve terminal ; thus, the relationship between a given muscle fibre and motor neuron is one-to-one.
