Order the following events that occur in a neuron in response
to a stimulus
Sodium Potassium Pumps and Potassium Leak Channels re-establish the resting potential Voltage Gated Potassium channels close The inside of the cell becomes more negative than the original resting potential V Voltage Gated Sodium channels open Sodium ions rush into the cell The inside of the cell becomes temporarily positive Votage Cated Potatalum channels open which causes potassium to flood out of the cell

ID: C 22 Sensory neurons transmit messages to the spinal cord or brain. from the central nervous system to a muscle or gland. from the brain to the spinal cord. d. All of the above 23. Which of the following statements about the resting potential of a neuron is true? Sodium ions are in balance inside and outside the neuron b. There are fewer potassium ions inside the neuron than outside. There are...
how are the sodium potassium pump and action potential related? as far as I know, the sodium potassium atpase pumps potassium in & sodium out, yet with the action potential sodium is pumped in (depolarization) and potassium is pumped out (repolarization). please explain how they are related?
A polarized neuron in its resting state has A. high potassium & high sodium ion concentratio inside the cell membrane B. High potassium ion concentration on the outside of the cell membrane and high sodium ion concentration on the inside of the cell membrane C. High sodium and high potassium ion concentrations outside the cell membrane D. high sodium and high potassium ion concentrations outside the cell membrane
What is a resting potential? Is it positive or negative? The resting potential is mainly due to the main _____-charged large molecules stuck inside the neuron. The Na+/K+ pump pushes Na+ _____ of the cell and K+ ____ of the cell (in or out for each ion) Where is K+ concentrated, inside or outside of the neuron? Where is Na+ concentrated, inside or outside of the neuron? The action potential starts with an rise in membrane voltage. This is due...
Question 17 3 pts Neurons cells are found in the nervous system and provide direct protection and physical support to the neurons. One protein made by these cells is myelin that is essential in neurological function as seen in epilepsy where the degeneration of the protein is observed and patients experience neurological symptoms. J Oection 10 Ante Question 15 2 pts Which one of the following establishes and maintains the resting potential of cells across the cell membrane? Na+ leak...

IDENTIFY THE NEURON TYPE PAGE 398 MARIEB Dendres Peripheral Cell body process Central Where do you find the cell body of neuron in #8? Inside or outside the CNS? Page 399 Marieb Where do you find the cell body of neuron in #197 Inside or outside the CNS? Resting membrane potential. Page 402. Which type of channels establish resting membrane potential?
Question 16 1.5 pts If a neuron is treated with a substance that inhibits the sodium-potassium pump, what would be the most immediate effect on the cell? the cell's membrane potential would immediately depolarize to 0 (zero) millivolts the cell's resting potential would slowly depolarize the cell would quickly run out of ATP the cell's osmotic balance would be disrupted and the cell would begin to swell no change at all
Hello, I need help in a MCQ question. Thank you. Which one of these processes causes the neuron to return to the "resting potential" from the state of "action potential"? 1) Ion channels allow positively charged ions to flow out of the neuron. 2) Sodium-potassium pumps remove positively charged ions from the inside of the neurons until the "polarized state" is restored. 3) Enzymes dissolve the positively charged ions in the cells. 4) Negatively charged ions flow into the neuron...
Neuroglia cells will make myelin in the nervous system. True False QUESTION 17 Sodium (Na+) will enter the neuron just before the action potential (nerve impulse) begins. True False QUESTION 18 Neurotransmitter permits nerve impulses to go between neuron cells. True False
