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.
The new leaf will contain 14 chromosomes, because during mitosis, a cell makes an exact copy of itself. Therefore, the number of the chromosomes in that cell stay the same.
