State of an unstimulated neuron's membrane?

An unstimulated neuron's membrane is polarized, with a negative charge inside the cell relative to the outside. This resting membrane potential is maintained by the unequal distribution of ions across the cell membrane, particularly sodium and potassium ions. The neuron is ready to generate an action potential when stimulated.


A small deviation from the resting membrane potential that makes the membrane more or less polarized?

This small deviation is called a graded potential. It can be either a depolarization, where the membrane becomes less polarized, or a hyperpolarization, where the membrane becomes more polarized. Graded potentials are important for transmitting signals over short distances in the nervous system.


What is the Electrical condition of a plasma membrane of a resting neuron?

The electrical condition of a plasma membrane of a resting neuron is polarized, meaning there is a voltage difference across the membrane with the inside being negatively charged compared to the outside. This resting membrane potential is typically around -70 millivolts.


What is a nerve membrane at rest called?

At rest, the nerve membrane is referred to as polarized, meaning there is a difference in electrical charge between the inside and outside of the cell. This difference is maintained by the sodium-potassium pump, which actively transports ions across the cell membrane.


What can stick to magnets?

anything that can become polarized such as metals


When a resting nerve fiber is polarized sodium and potassium ions is higher on the inside of its membrane?

A resting nerve fiber is polarized because the concentration ofNa+ is higher on the outside and K+ is higher on the inside.


How is the polarized membrane state maintained?

Because the voltage across a neural membrane is approximately -70mv, the inside of the membrane is negatively charged relative to the outside. Therefore, it is polarized; this polarization is maintained by retaining a low concentration of Na+ ion and a high concentration of K+ inside the cell (relative to the outside). Active transport helps this to occur, especially the Na+-K+ pump.THis was a question on my homework too. Hope i helped =).


How can sunlight be polarized?

Sunlight can become polarized when it interacts with the Earth's atmosphere, such as through scattering or reflection off surfaces. This causes the light waves to align in a specific orientation, creating polarization. Specialized filters, like polarized sunglasses, can then block out this polarized light to reduce glare.


Explain how polarized light is different from non-polarized light.?

In polarized light, the plane of the electrical (and magnetic) oscillations is the same for all photons (particles of light). For example, if the light is traveling away from you, all photons might have electrical oscillations that go up and down.


Why is sarcolemma polarized?

The sarcolemma is polarized because it has different concentrations of ions inside and outside the muscle cell. This creates an electrical potential difference across the membrane, known as the resting membrane potential. This polarization is important for muscle cell function, including the generation and propagation of action potentials.


What model is used to explain the componets and properties of plasma membrane?

The Fluid Mosaic Model is used to explain the components and properties of the plasma membrane. This model describes the plasma membrane as a dynamic structure composed of a lipid bilayer with embedded proteins that can move and interact within the membrane.


When there are fewer positive ions sitting on the inner face of the neurons plasma membrane than there are on the outer face of the tissue fluid that surrounds it said to be?

Polarized
