Compared to the inside of the resting plasma membrane the outside surface of the membrane is?
The outside is slightly positive while the inside is slightly negative.
Electrical charge resulting from the difference between positive and negative ions outside and inside the brain cell membrane is called?
Membrane potential
When the inside of a cell is negatively charged while the outside of the cell is positively charged it is known as resting potential true or false?
True.
The state during which a neuron contains more negatively charged ions inside the cell than outside the cell and is not firing is referred to as the?
resting potential
In the absence of stimuli all cells in the body maintain a potential difference across the semipermeable membrane in which the inside of the cell is negatively charged in comparison to the outside?
resting membrane potential
Which channel is mainly responsible for the resting potential of a neuron?
Potassium leak channel
Are there more sodium ions inside or outside a cardiac muscle cell during the resting membrane potential?
Outside
When a neuron is resting the inside of the cell membrane is?
When a neuron is resting then inside of the cell membrane is more negative than outside.
A resting neuron is when?
A neuron is at rest when theinside is negatively chraged compared to the outside.
Compared to the inside of the resting plasma membrane the outside surface of the membrane is?
The outside is slightly positive while the inside is slightly negative.
What ion determines the resting membrane potential of nerve and muscle?
The concentrations on Na+ outside the cell and concentrations of K+ inside the cell determine the resting membrane potential.
Why is the resting potential value of a membrane negative?
The resting membrane potential is the difference between the inside of the cell relative to the outside. The outside is always taken as 0mv. The resting membrane potential is negative because there is a higher concentration of potassium ions outside the cell (because the membrane is more permeable to potassium ions) than inside. Since potassium ions are positively charged this leads to a negative value.
Is resting potential caused by a difference in the concentration of certain ions inside and outside the cell?
True
A resting potential is caused by a difference in the concentration of certain ions inside and outside the cell?
True
What can affect the amount of friction on an object?
the weight of the object, what its outside consists of, the nature of the surface it resting on.
What is the approximate resting potential of a neuron?
It is -70 millivolts. The resting potential of a neuron refers to the voltage difference across the plasma membrane of the cell, and is expressed as the voltage inside the membrane relative to the voltage outside the membrane. The typical resting potential voltage for a neuron is -70mV Resting potentials occur because of the difference in concentration of ions inside and outside of the cell, largely by K+ (Potassium ions) but some contribution is made by Na+(Sodium ions)
Is the resting potential of a neuron 50-100 mV with the inside of the cell more negative than the outside?
It depends on what the sign is before your number. A positive sign in front of the number indicates that the inside of the cell is more positive when compared to the outside; a negative sign in front of the number indicates that the cell is more negative compared to the outside. The resting potential of a neuron is always negative when compared to the outside of the neuron, and usually lies around -90mV. For different cells in the body, the resting potential may vary but it will always be negative :)!
