At its simplest, the neuromuscular junction is a type of synapse where neuronal signals from the brain or spinal cord interact with skeletal muscle fibers, causing them to contract.
The activation of many muscle fibers together causes muscles to contract, which in turn can produce movement. The neuromuscular junction then, is a key component in the body’s ability to produce and control movement. Amazingly, processes at the neuromuscular junction take place at speeds that allow movements to occur with no appreciable delay or lag.
This article will discuss the anatomy and function of the neuromuscular junction.
