Answer
Acetylcholine
Explanation
## Step 1:The question asks about the neurotransmitter that is released at the neuromuscular junction to activate receptors on the muscle cell membrane. The neuromuscular junction is the point where a motor neuron meets a muscle cell.## Step 2:Among the options given, we know that acetylcholine is the neurotransmitter that is primarily involved in the neuromuscular junction. It is responsible for transmitting signals from the motor neuron to the muscle fiber, which leads to muscle contraction.## Step 3:The other neurotransmitters listed - noradrenaline, dopamine, and serotonin - have different primary functions. Noradrenaline is mainly associated with the body's fight or flight response, dopamine is involved in reward and motivation pathways in the brain, and serotonin is involved in mood regulation. Therefore, they are not the primary neurotransmitters at the neuromuscular junction.
