Question

Place the events in the transmission of an action potential in the correct order: 1) An action potential begins in the receiving neuron. 2) Neurotransmitters are released into the synaptic cleft. 3) An action potential arrives at an axon terminal. 4) Calcium ions enter the axon terminal. 5) Sodium ions diffuse into the receiving neuron. 6) Synaptic vesicles fuse with the plasma membrane. 7) Neurotransmitter molecules bind to the membrane of the receiving neuron.

Answer 1

Answer:

Ello mate, Here's you're answer !

The correct order is 3,4,6,2,7,5,1

Explanation:

Here are the events in the transmission of an action potential in the correct order :

3)An action potential arrives at an axon terminal. 4) Calcium ions enter the axon terminal.  6) Synaptic vesicles fuse with the plasma membrane.2) Neurotransmitters are released into the synaptic cleft. 7) Neurotransmitter molecules bind to the membrane of the receiving neuron.5) Sodium ions diffuse into the receiving neuron.1) An action potential begins in the receiving neuron.

Answer 2

An action potential can be defined as a sudden, fast change in electrical (voltage) potential with respect to the transmission of an impulse across a cellular membrane such as a nerve cell or muscle cell.

Basically, a neuron transmits electrical impulses down an axon across a cellular membrane of the body of a living organism through a process referred to as an action potential.

The correct order of events involved in the transmission of an action potential include the following:

• An action potential arrives at an axon terminal which causes the opening of the calcium channel.

• Calcium ions travels down the length of an axon terminal.

• Synaptic vesicles containing chemicals called neurotransmitters, fuse with the plasma membrane.

• These chemicals (neurotransmitters) are then released into the synaptic cleft between two neurons.

• The neurotransmitter molecules bind to the receiving neuron's membrane.

• Sodium ions are diffused into the receiving neuron.

• Finally, an action potential begins within the receiving neuron.

In conclusion, the correct order of events involved in the transmission of an action potential are: 3, 4, 6, 2, 7, 5, and 1.
