Some versions in Mexico use rehydrated dry chiles such as anchos or pasillas. In the United States, chiles rellenos are usually filled with asadero, asiago, or Monterey Jack cheese, but can also be found with cheddar or other cheeses. The chile is then dipped in an egg batter and either pan-fried or deep-fried.
â¢ The neuromuscular junction is the place where the terminal portion of a motor neuron axon meets a. muscle cell membrane, separated by a synaptic cleft. â¢ An action potential arriving at the axon terminal brings about the release of acetylcholine, which. leads to depolarization of the motor end plate.verview of Neuromuscular Junction Activityâ¢ The muscle cell, including the T Tubules are polarized. Stimulation of the motor end plate on amuscle cell by acetylcholine triggers depolarization resulting in contraction of the sarcomeres.Page 6.
The neurotransmitter at excitatory synapses depolarizes the postsynaptic membrane (of a neuron in this diagram). 1  Binding of acetylcholine to its receptors on the postsynaptic cell opens up ligand-gated sodium channels. 2  These allow an influx of Na + ions, reducing the membrane potential.he junction between the axon terminals of a neuron and the receiving cell is called a synapse. (Synapses at muscle fibers are also called neuromuscular junctions or myoneural junctions 1  .). Action potentials travel down the axon of the neuron to its end(s), the axon terminal(s).
