Question

Put the following statements about a synapse in the correct order.

= Vesicles filled with neurotransmitters move to the end of the axonal terminal
= Neurotransmitters attach to the sodium channels on the dendrite.
= Action Potential reaches the Axonal terminal
= Sodium channels open
= Neurotransmitters are released into the synaptic cleft
= Sodium moves into the Dendrite
= Action potential travels through the dendrite

Answer 1

Action Potential reaches the Axonal terminal

Vesicles filled with neurotransmitters move to the end of the axonal terminal

Neurotransmitters are released into the synaptic cleft

Neurotransmitters attach to the sodium channels on the dendrite.

Sodium channels open

Sodium moves into the Dendrite

Action potential travels through the dendrite

Step-by-step explanation:

The process of transmission of action potential across a synapse ( a junction between two neurons) begins with the arrival of an action potential from the presynaptic neuron. The steps are given below:

Action Potential reaches the axonal terminal of the presynaptic neuron

Vesicles filled with neurotransmitters move to the end of the axonal terminal of the presynaptic neuron

Neurotransmitters are released into the synaptic cleft

Neurotransmitters attach to the sodium channels on the dendrite of the postsynaptic neuron

Sodium channels open

Sodium moves into the dendrite of the postsynaptic neuron.

Action potential travels through the dendrite towards an effector or another neuron.
