What causes cell membrane to depolarize?
It's during the "rising phase" when the membrane potential becomes more positive.
What is the cell that converts vibrations into neurological impulses?
The hair cells of the organ of Corti vibrate and depolarize the neurons associated with them. used Hole's 11th edition of Health anatomy and physiology!
Does action potential invole the influx of negative ions to depolarize the membrane?
First one must outflux negative ions because the inner cell membrane is already slightly negative.
Involves the influx of negative ions to depolarize the membrane?
Action Potential
Proteins unwind or what when placed in extreme pH or temperature conditions?
depolarize
Does a neuron depolarize or hyperpolarize while you sleep?
Hyperpolarize
What effect will Raising the potassium ion concentration in the extracellular fluid surrounding a nerve cell have?
Both hyperpolarize it and decrease the magnitude of the potassium equilibrium potential.
Where is the cell body that causes SA node cells to depolarize faster?
Dr. Poe wouldn't like you to use this site!
What causes cell membrane to depolarize?
It's during the "rising phase" when the membrane potential becomes more positive.
Hyperkalemia have on the nervous system?
Hyperkalemia decrease a cell's membrane potential beyond the threshold value so it can't depolarize again.
Does an increase or decrease in potassium extracellular ions hyperpolarize a cell?
An extracellular increase of potassium (increase of intracellular Sodium) causes depolarization. The opposite, I presume, meaning high intracellular potassium (inside cell) and high extracellular sodium (outside cell) would be hyperpolarization
Neurotransmitters categorized as inhibitory would not be expected to?
Hyperpolarize the Membrane
Why increasing extracellular potassium ion reduces the net diffusion of potassium ion out of neuron through the potassium leak channel?
By increasing the extracellular K+ there is efflux and also influx into the cell which increases the tendency of the cell to depolarize.
When does a QRS complex occurs?
When ventricles depolarize
What is the cell that converts vibrations into neurological impulses?
The hair cells of the organ of Corti vibrate and depolarize the neurons associated with them. used Hole's 11th edition of Health anatomy and physiology!
What do node cells of the heart depolarize?
purkinje fibers
Does action potential invole the influx of negative ions to depolarize the membrane?
First one must outflux negative ions because the inner cell membrane is already slightly negative.
