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.

The major energy fuel for the central nervous system?
ATP
Contrast Chemical energy and mechanical energy?
chemical energy is when the energy that is released when a chemical compound reacts to produce new compounds. A mechanical energy is the sum of the kinetic and potential energy of large-scale objects in a system.
When was Chemical energy first used?
Chemical energy is used by any system that converts energy by combining or decomposing chemical bonds. Chemical energy was first used when the first molecule was formed, billions of years ago.
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 potential energy is energy of chemistry or?
Potential energy is the energy due to position of a body in a force field. There is a type of potential energy called Chemical Potential energy for example energy stored in fuels.
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.
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 is the energy transfer in a battery powered gaming system?
the energy transfer is from chemical to electrical to radiant
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
How does the heart get energy for functioning?
Most likely from the central nervous system. The brain fires off electrical pulses making the heart beat. The energy in the brain is generated from chemical energy, the body works off of a type of biological battery. It gets its potential energy differences from food, water and air.
Cells that transmit electrical signals through the nervous system to various organs in the body are called?
This is the nervous system.
What system controls muscles and regulates body activity?
The nervous system controls muscles and glands by electrical impulses.
What advantage does the nervous system have over the endocrine system?
The messages of the nervous system are relayed by nervous impulses, which are very fast and short-acting. In contrast, the messages of the endocrine system are sent via chemical messengers (hormones) distributed by the circulatory system. This distribution in your blood is much slower than the electrical impulses of the nervous system.
Which system shows a transformation from chemical to electrical and light energy?
A car battery causes the headlights to shine
What is an e word for the nervous system?
eglomerate, electrical
What part of the autonomic nervous system that conserves body's energy?
The parasympathetic nervous system.
