Now, the axon terminal is right next to our cell membrane of the muscle cell. In this case, let's say it's a skeletal muscle found inside my bicep. So if we zoom in on a synapse, this is basically our neuromuscular junction. It's the synapse between our neuron, the motor neuron, and our cell membrane of that muscle. So if we zoom in, we basically get the following picture. So, we have the axon terminal of our somatic motor neuron, and we have the cell membrane of the skeletal muscle inside our biceps muscle.
