Drag each tile to the appropriate bin to indicate whether it shows the neuromuscular junction at rest or active (in the process of transmitting a signal).

Neuromuscular Junction  - It is a chemical synapse formed by the contact between a motor neuron and a muscle fiber.

Function- As the motor neuron are able to transmit the required signals to the muscle fiber, which causes the muscle contraction.

Explanation:

Steps in neuromuscular transmission:

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.

Hahaha good one. you ? & oop
