The effect of a neurotransmitter on the muscle cell membrane is to modify its ion permeability properties temporarll) True False Submit Request Answer

True! Neurotransmitters play a crucial role in communication between nerve cells and muscle cells. When a neurotransmitter binds to receptors on a muscle cell's membrane, it can lead to a temporary change in ion permeability. This allows ions like sodium and calcium to flow in or out of the muscle cell, triggering muscle contractions or relaxation. In real-world applications, understanding this mechanism is essential in fields such as medicine and physiology. For example, many anesthetics and muscle relaxants work by interfering with neurotransmitter activity at the neuromuscular junction, which can prevent muscle contractions during surgery and help manage pain.
