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.
3. Describe the process of excitation-contraction coupling in skeletal muscle fibers. ACH is released at the end-plate potential. ACH diffuses into the sarcolemma, attaches to the receptors in the motor end plate and causes a change in the ions permeability that creates graded depolarization of the end-plate potential.
