Acetylcholine is the neurotransmitter that plays a crucial role in muscle stimulation at the neuromuscular junction. When a motor neuron sends a signal to a muscle fiber, acetylcholine is released from the nerve terminal into the synaptic cleft. This neurotransmitter then binds to specific receptors on the muscle cell membrane, leading to depolarization of the muscle cell and ultimately resulting in muscle contraction.

Understanding the function of acetylcholine is essential, especially in the context of muscular physiology and overall neuromuscular function. Its release and action are key to initiating movement and enabling muscle contractions in response to neural signals.
