Question

Which of the following represents the path that an action potential travels as it moves from one neuron to another?

Axon of first neuron to axon of second neuronAxon, dendrites, and cell body of first neuron to axon of second neuronAxon of first neuron to dendrites, cell body, and axon of second neuron
A) True
B) False.
The influx of calcium ions at the synaptic terminal causes the fusion of synaptic vesicles with the terminal membrane and results in the release of neurotransmitters that bind to postsynaptic ion channels.

Answer 1

Answer (True)Axon of first neuron to dendrites, cell body, and axon of second neuron

(True)The influx of calcium ions at the synaptic terminal causes the fusion of synaptic vesicles with the terminal membrane and results in the release of neurotransmitters that bind to postsynaptic ion channels.

Step-by-step explanation:

The first answer explains the transmission pathway of action potential in a neuron with ELECTRICAL SYNAPSE at dendrites.

This is an exemple of SULTATORY CONDUCTION,because the action potential jumps from one Nodes of Ranvier to another along the axon.

The second answer explains transmission from pre-synaptic neuron ,with CHEMICAL SYNAPSE initiated by calcium ion in influx into the synaptic cleft at terminal ends; for transmission of action potential to the post synaptic neuron to induce inhibition or excitation of muscles.

The neurotransmitters released binds with the receptors on the post synaptic neuron to ensure crossing /transmission of action potential
