What type of neurone carry electrical signal to the brain?
Afferent neurons (also called sensory neurons) carry signals to the central nervous system and the brain. Efferent neurons (also called motor neurons) carry signals from the brain.
How does your nervous system send signals to other body systems?
The basic signal in the nervous system is called an action potential. It is a rapid change in the surface charge of the cell membrane from a value around -70mV to 30 mV over several milliseconds controlled by the selective flow of sodium Na+, calcium Ca++ and potassium K+ ions (mostly).
Nervous tissue contains specialized cells called?
Neurons are the conducting cells of nerve tissue. The neurons transmit the electrical charges and chemical signals via the synapses.
An electrical charge in motion called?
An electrical charge in motion is called a current.
Nerves that transmits message from the rods and cones?
The nerves that transmit messages from the rods and cones are called optic nerves. Rods and cones are specialized cells in the retina of the eye that detect light and convert it into electrical signals. These signals are then transmitted through the optic nerves to the brain, where they are processed and interpreted as visual information.
How do the electrical pattern in electronics convey information?
With analog and digital signals.
What is the part of your eye that has cells to convert light images into electrical signals?
It is called the RETINA
What is the conversion of the vehicles kinetic energy into electrical energy called?
Dynamic breaking.
What procedure is involved in an electrophysiology study of the heart?
four to 10 electrodes are located on the end of the catheters, which have the ability to send electrical signals to stimulate the heart (called pacing) and to receive electrical signals from the heart
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.
Clustered in their heads sharks have sense organs called the ampullae of Lorenzini What do they detect?
Electrical signals
How the nerves transmit signals to the brain?
Nerves use electrical impulses to transmit signals to the brain. The gaps between the nerve endings are called synapses.
A testing instrument that's used to measure electrical signals in a circuit and display them as waveforms on a screen is called?
an oscilloscope
What are Irregular fluctuations which tend to obscure electrical signals or radio reception also called static?
White noise
What is Optical line terminal?
An optical line termination (OLT), is a device which serves as the service provider endpoint of a passive optical network. It provides two main functions: - To perform conversion between the electrical signals used by the service provider's equipment and the fiber optic signals used by the passive optical network. - To coordinate the multiplexing between the conversion devices on the other end of that network (called either optical network terminals or optical network units).
For radio broadcasts sound signals are converted to?
For radio broadcasting, sound waves are converted to electrical waves that are further transmitted. This transformation is done by a device called a transducer, which converts physical parameters into an electrical form (signals).
How do you record the electrical activity of the heart?
The electrical activity of the heart is recorded using an electrocardiogram (ECG or EKG) machine. This machine detects the electrical signals generated by the heart and produces a graphical representation of the heart's electrical activity called an ECG tracing. Electrodes are placed on the skin to capture these signals and can help diagnose heart conditions.
