What happens when a neural signal reaches the neuromuscular junction?

What happens when a neural signal reaches the neuromuscular junction?
  1. Calcium ions are released into the sarcoplasm
  2. Cross-bridge formation between actin and myosin
  3. Release of neurotransmitter acetyl choline
  4. Relaxation of the muscle

Solution

When a neural signal reaches the neuromuscular junction, it releases a neurotransmitter (Acetylcholine) which generates an action potential in the sarcolemma.
