The two major features that distinguishes nervous tissue is that selective permeability to ions is controlled by voltage and receptor controlled channels and that the density of ion pumps is much greater than that found on non-excitable membranes. The potential difference between the inside and and outside of a cell (most neurons are negative with respect to outside the cell) is the result of moving ions. So it is a change in the chemical composition inside the cell that results in an electrical change.

What energy can be transformed to kinetic chemical electrical or thermal energy?
Potential energy can be transformed into kinetic, chemical, electrical, or thermal energy depending on the system or process involved. Gravity, chemical bonds, or electrical potential can store potential energy that can be converted into various forms of energy when those bonds are broken or released.
Why is chemical energy the energy that is converted to thermal energy?
Various kinds of energy may be converted into thermal energy.In a fire it is chemical energy that is converted to thermal energy.However:In a nuclear reactor, nuclear energy is first converted to thermal energy, and eventually to electrical energy.In a fire chemical energy is also converted to light energy.In a battery chemical energy is converted to electrical energy.In braking systems kinetic energy is converted to thermal energy.
What is the major energy fuel for the central nervous system?
well, as we all know the central nervous system is fueled by chocolate milk. SO GO DRINK SOME.
What is the relationship between chemical potential and Gibbs free energy in a chemical system?
In a chemical system, the chemical potential is related to the Gibbs free energy. The chemical potential represents the energy required to add one molecule of a substance to the system, while the Gibbs free energy is a measure of the system's overall energy available to do work. The relationship between the two is that the change in Gibbs free energy of a reaction is related to the change in chemical potential of the reactants and products involved in the reaction.
Does the nervous system use electricity?
Yes, the nervous system uses electrical signals to transmit information throughout the body. Neurons generate electrical impulses called action potentials to communicate with each other and with other cells. This electrical activity allows for the coordination of various physiological processes and responses.
Cells that transmit electrical signals through the nervous system to various organs in the body are called?
Neurons are the cells that transmit electrical signals through the nervous system to various organs in the body. They are specialized cells that can receive, process, and transmit information via electrical and chemical signals.
Which system sends and receives messages within the body?
There isn't any. You're thinking of the nervous system - but the messages are all chemical. The electrical activity is a side effect.
Which system shows a transformation from chemical to electrical and light energy?
A system that demonstrates a transformation from chemical to electrical and light energy is a battery-powered LED flashlight. The batteries store chemical energy, which is converted into electrical energy to power the LED light, producing light energy as a result.
What is responsible for carrying information from the central nervous system to tissue?
Motor Neurons and the chemical and electrical interactions between them carry information from the central nervous system to tissues.
What nervous cell is 90 percent of the nervous system?
The neuron is the nervous cell that makes up about 90 percent of the nervous system. Neurons are the basic building blocks of the nervous system and are responsible for transmitting electrical and chemical signals throughout the body.
What is the energy transfer in a battery powered gaming system?
the energy transfer is from chemical to electrical to radiant
The process of receiving and representing stimulus energies by the nervous system is called?
The process of receiving and representing stimulus energies by the nervous system is called sensory transduction. This is where sensory receptors convert physical or chemical stimulus energy into electrical signals that can be transmitted and processed by the brain.
How signals move through the nervous system?
In the nervous system, electrical signals travel throughout the brain and into the body via nerves and nerve fibers. Electrical signals are how the brain tells the body what it should do.
Is the nervous system electrical?
Yes
What is the fundamental building block of the nervous system?
The fundamental building block of the nervous system is the neuron. Neurons are specialized cells that transmit information throughout the body via electrical and chemical signals. They play a crucial role in enabling communication within the nervous system.
What energy can be transformed to kinetic chemical electrical or thermal energy?
Potential energy can be transformed into kinetic, chemical, electrical, or thermal energy depending on the system or process involved. Gravity, chemical bonds, or electrical potential can store potential energy that can be converted into various forms of energy when those bonds are broken or released.
What system controls muscles and regulates body activity?
The nervous system controls muscles and glands by electrical impulses.
