WebThe neuromuscular junction is where an electric impulse travels to instruct the muscle system to make a move. A neuromuscular junction consists of an axon terminal of a motor neuron and the motor end plate of a muscle fiber. The axon terminal splits into multiple tiny branches, each ending in a bulblike structures, named the terminal button. WebDec 11, 2024 · Neuromuscular junction disorders are a group of conditions that cause muscle weakness. Their etiology can be autoimmune, congenital, metabolic, or toxic mediated.
