Question

What is the correct order of a signal being transmitted across a neuromuscular junction? Neurotransmitter—neuron—receptor protein-motor end plate Neurotransmitter—receptor protein—motor end plate—neuron Neuron—receptor protein—neurotransmitter—motor end plate Neuron—neurotransmitter—receptor protein—motor end plate

Answer 1

The neuromuscular junction (NMJ) is the site of communication, a chemical synapse, between motor nerve axons and muscle fibers. This junction transmit ssignals from the motor neuron to the skeletal muscle fibre quickly and reliably. The goal is to ensure precise control of skeletal muscle contraction and therefore voluntary movement.  The correct order of a signal being transmitted across a neuromuscular junction is the following: Neuron-neurotransmitter-receptor protein-motor end plate.

Answer 2

Neuron—receptor protein—neurotransmitter—motor end plate
