Witryna3 sty 2024 · The neuromuscular junction is the point at which motor neurons connect with skeletal muscle. It is at this juncture that the chemical messenger, known as a … WitrynaAnswer: The neuromuscular junction is the area where a motor nerve sends signals (impulses) to muscles, which causes the muscle to contract in response. Some examples of its importance are: 1. If a signal sent out by the nervous system does not make it to the muscle, we have paralysis. 2. If a s...
