The correct sequenceof impulse travel through neuronis cell body to axon
Axon
An axon, or nerve fiber, is a long, slender projection of a nerve cell, or neuron, in vertebrates, that typically conducts electrical impulses known as action potentials away from the nerve cell body. The function of the axon is to transmit information to different neurons, muscles, and glands. In certain sensory neurons, such as those for touch and warmth, the axons are called afferent nerve fibers and th…
What is the sequence of events of a nerve impulse?
sequence of events of a nerve impulse STUDY Flashcards Learn Write Spell Test PLAY Match Gravity Created by carotc Terms in this set (7) 1 Nerve impulse travels down axon of pre-synaptic nerve and sodium enters and cell depolarizes. 2 Impulse/depolarization opens channel proteins on the membrane allowing CA to enter. 3
What is the sequence of events in a neuron when it receives?
Sequence of events in a neuron when it receives a stimulus sufficient to reach threshold: Once threshold has been reached: 1) Cell depolarizes- Na+ ions move inside the cell leaving the inside of cell positive and outside negative 2) Cell repolarizes- K+ ions move outside of the cell, returning it to a negative charge
What happens in a neuron when it receives a stimulus?
Sequence of events in a neuron when it receives a stimulus sufficient to reach threshold: Once threshold has been reached: 1) Cell depolarizes- Na+ ions move inside the cell leaving the inside of cell positive and outside negative
What is the function of a synapse Quizlet?
Explanation: The synapse is a neuronal junction which acts as the site for transmission of nerve impulse between two neurons. This synapse along with its neurotransmitters acts as a physiological valve, directing the conduction of nerve impulses in regular circuits and prevents random and chaotic stimulation of nerves.
In which sequence does a neural impulse travel through a neuron?
The correct outline for the sequence of transmission of an electrical impulse through a neuron is dendrites, cell body, axon, axon terminal.
What are the 5 steps of a neural impulse?
Terms in this set (6)Resting neuron: The plasma membrane at rest is polarized. ... Action potential initiation and generation: A stimulus depolarizes the neurons membrane. ... Action potential initiation and generation: ... Propagation of the action potential: ... Repolarization: ... Repolarization:
What is the sequence of events of a nerve impulse?
Nerve impulse travels down axon of pre-synaptic nerve and sodium enters and cell depolarizes. Impulse/depolarization opens channel proteins on the membrane allowing CA to enter. Calcium prompts vesicles to open neurotransmitters in to synaptic cleft. Neurotransmitters bind to receptors of post-synaptic neuron.
What is the correct order for information to pass through a neuron?
A neuron is the functioning unit of the nervous system; specialized to receive, integrate, and transmit information. The flow of information moves in the following direction: dendrite to soma to axon to terminal buttons to synapse.
What are the 5 steps of an action potential?
What Are The 5 Steps Of An Action Potential?Resting potential.Threshold.Rising phase.Falling phase.Recovery phase.
How does a nerve impulse travel down a neuron?
A nerve impulse begins when a neuron receives a chemical stimulus. The nerve impulse travels down the axon membrane as an electrical action potential to the axon terminal. The axon terminal releases neurotransmitters that carry the nerve impulse to the next cell.
Which of the following sequences shows the pathway followed by a nerve impulse when one neuron communicates with another?
Thus, the correct answer is 'Cell body-Axon-Nerve terminal'.
What are the four steps of an action potential in order?
Terms in this set (4)Step 1 - Resting Potential. Sodium and potassium channels are closed. ... Step 2 - Depolarization. Sodium channels open in response to a stimulus. ... Step 3 - Repolarization. Na+ channels close and K+ channels open. ... Step 4 - Resting Conditions. Na+ and K+ channels are closed.
What is the correct sequence of events that occurs along an axon after the membrane reaches threshold?
When the membrane potential of the axon hillock of a neuron reaches threshold, a rapid change in membrane potential occurs in the form of an action potential. This moving change in membrane potential has three phases. First is depolarization, followed by repolarization and a short period of hyperpolarization.

Which of the following is the correct sequence for passage of sensory impulses through the cells of the retina?
So the correct option is 'Photosensorycells→Bipolarneurons→Ganglioniccells→Sensorynerves'.
How does information flow through a neuron quizlet?
In general, flow of information in a neuron occurs in the following manner. Signals are received at the dendrites, processed in the cell body, and passed to other neurons via the axon.
