Answer:
<u> Neuromuscular Junction -</u> It is a chemical synapse formed by the contact between a motor neuron and a muscle fiber.
<u>Function- </u>As the motor neuron are <em>able to transmit the required signals</em> to the muscle fiber, which causes the muscle contraction.
Explanation:
<u>Steps in neuromuscular transmission:</u>
- nerve action potential.
- calcium entry into the presynaptic terminus.
- release of Ach quanta.
- diffusion of Ach across cleft.
- combination of Ach with post-synaptic receptors and Ach breakdown via esterase.
- opening of Na + /K + channels (cation channels).
- postsynaptic membrane depolarization (EPP).
- muscle action potential.
