Question

When the nerve signal reaches the axon terminal, what happens next? a. The muscle contracts. b. The synaptic vesicles release neurotransmitter. c. An electrical signal is formed that jumps the synaptic cleft. d. H+ is pumped into the synaptic cleft. E. Myosin is released from the axon terminal.

Answer 1

Answer:

b. The synaptic vesicles release neurotransmitter.

Explanation:

As the action potential would be reaching the terminal of the motor neurons, there would be opening of the calcium channels . This opening of the calcium channels would be allowing entry of calcium in the axon terminals . Because of this entry, the synaptic vesicles would be releasing neurotransmitters such as acetylcholine , through the process of exocytosis .
