When a nerve fiber is polarized, there is a difference in ion concentrations across its membrane, primarily involving sodium (Na⁺) and potassium (K⁺) ions. The inside of the fiber becomes negatively charged relative to the outside, as there is a higher concentration of K⁺ ions inside and Na⁺ ions outside. This polarization is essential for the generation and propagation of action potentials, allowing the nerve to transmit signals.
What else can I help you with?
True or false Fiber concentration is found only in the skins of fruits and vegetables?
While it's true that many fruits and vegetables have a greater concentration of fiber when consumed with the skin, some fruits and vegetables have a high fiber content even without it. For example, cantaloupes, grapefruit, bananas, spinach, and carrots all have high fiber content.
When a nerve fiber is polarized the concentration is what?
When a nerve fiber is polarized, the concentration of sodium ions is higher outside the cell, while the concentration of potassium ions is higher inside the cell. This concentration gradient helps maintain the resting potential of the neuron.
What is the food with the highest conentration of fiber?
the food that has the highest concentration of fiber is bran. Other foods high in fiber are corn, peppers, flax seeds, sesame seeds, tomatoes and soy beans.
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.
Why should electrolytic capacitors not to be used in AC circuits?
Electrolytic caps are polorized and are used for filtering and will charge up to a DC value as in power supplies.
Why is polarization good for sunglasses?
Polorized sunglasses will reduce glare!Example...if you wear polorized glasses to the lake...you will be able to see into the water instead of the glare on top of the water!The uv protection isn't better or worse with polorized.......it basically does the squinting for you!Most people that spend alot of time on the water will use polorized..fishing,etc!They are great for driving to...just becareful if your window is already polorized you wont see through it, if you have polorized glasses on..it will look distorted!you wont be able to read digital clocks and stuff as well!!
Are all polorized sunglasses made of glass?
Hey, no polarized sunglasses can be made of different materials. Not only glass, but also of plastic and Polycarbonate. Check this site www.smartbuglasses.com
What are the rough parts of fruits and vegetables called?
Fiber
What are A fiber B fiber and C fiber?
B-fiber are DULL PAIN!
How does nerve fiber become depolarized?
A nerve fiber becomes polarized when the resting potential of the membrane changes. It starts out with an unequal distribution of charges- the outside is more positive and the inside is less positive. (Sodium (Na+) is in a higher concentration on the outside of the membrane and Potassium (K+) is in a lower concentration on the inside of the membrane.) A stimulus changes the gradient- when more Na+ flows in, the resting potential changes and polarization occurs, allowing for an action potential to be propagated down the axon.
Why is it best to eat vegetables unpeeled?
While this is generally true, it isn't always true. The outer parts of some vegetables are richer in dietary fiber, can be richer in iron from the chromophores and contain other vitamins (like vitaman A) in higher concentrations than the inner parts of the vegetable. On the other hand a higher concentration of dietary fiber sometimes leads to leeching of iron out of the body as the iron binds tighter to the dietary fiber than to the transport proteins and as a result the iron is excreted along with the fiber.
What is orlon fiber?
