Abstract:
In this study we demonstrate expression of the N-methyl-D-aspartate receptor NR1 subunit in the rat neuromuscular junction of skeletal muscles of different functional types (extensor digitorum longus, soleus, and diaphragm muscles) using fluorescence immunocytochemistry. Electron microscopic immunocytochemistry has shown that the NR1 subunit is localized solely on the sarcolemma in the depths of the postsynaptic folds. These findings suggest participation of the glutamatergic signaling system in functioning of the adult mammalian neuromuscular junction.

When an action potential reaches the axon terminal, it depolarizes the membrane and opens voltage-gated sodium channels. Sodium ions enter the cell, further depolarizing the presynaptic membrane. This depolarization causes voltage-gated calcium channels to open.
