What does transcutaneous electrical nerve stimulation do?
Transcutaneous electrical nerve stimulation (TENS) uses a battery-powered device generating weak electrical impulses applied along the course of affected nerves to block pain signals traveling to the brain.
What pathway converts privates into lactate?
The pathway that converts pyruvates into lactate is actually part of the PA pathway. The total result of the PA pathway is to convert pyruvates into acetate, with conversion to lactate being one of the reactions along the way.
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).
Why does a message moving along nerve pathways take time to get to the brain?
because its lazy!!
What travels along the optic nerve from the eye to the brain?
Visual information in the form of electrical signals travels along the optic nerve from the eye to the brain. These signals are generated by the photoreceptor cells in the retina and are then transmitted through the optic nerve to be processed in the visual cortex of the brain, allowing us to perceive and interpret what we see.
How do you use strolling in a sentence?

What is a communications device that sends electrical signals along a wire?
telephone
What is neural pathway?
You can think of a brain pathway as a power line that connects two brain regions. Brain pathways are made up of interconnected neurons along which signals are transmitted from one brain region to another.
Why do you need both conductors and insulators in electrical appliances?
To make electricity go where you want it to go, so it will do what you want it to do, you have to provide a pathway along which it can travel, made of conductors, and barriers around that pathway, made of insulators, to keep it from leaking out of the desired pathway.
Along myelinated sections between nodes in a myelinated axon electrical signals are conducted by?
saltatorial conduction
What signal travels along the axon?
The high-speed signals that pass along the axon are called action potentials. They spread in a wave of depolarization.
Which types of electromagnetic waves can be used to send signals along optical fibers?
Only light is used to send signals along optical fibres. That's why this type of fibre is described as "optical". Fibres designed to conduct electrical signals are referred to as "wires".
What is the transmissor for the sense of taste?
The gustatory pathway has a more complicated course. There are more fiber tracts involved in the transmission of the neural impulses for taste. The facial nerve transmits gustatory signals or messages from the anterior two-third of the tongue. However, for the posterior one-third of the tongue,the glossopharyngeal nerve is responsible for the transmission of the gustatory signals along the pathway.
What are evoked potential studies?
Evoked potential studies measure the electrical activity in the brain in response to specific stimuli, such as visual or auditory signals. They can provide valuable information about the function of the nervous system, including detecting abnormalities in sensory processing or tracking the progression of diseases like multiple sclerosis. These studies are non-invasive and can help diagnose conditions affecting the brain and nervous system.
Guided versus unguided network?
Guided Media : Guided Transmission Media uses a "cabling" system that guides the data signals along a specific path. The data signals are bound by the "cabling" system. Guided Media is also known as Bound Media Unguided Transmission Media consists of a means for the data signals to travel but nothing to guide them along a specific path. In a guided medium signal passes through a physical pathway(s),while in an unguided medium signal passes through a vacuum, it is independent of a physical pathway.
What does transcutaneous electrical nerve stimulation do?
Transcutaneous electrical nerve stimulation (TENS) uses a battery-powered device generating weak electrical impulses applied along the course of affected nerves to block pain signals traveling to the brain.
What is Trancutaneous electrical Nerves Stimulator?
TRANSCUTANEOUS ELECTRICAL NERVE STIMULATOR IS ANY STIMULI (ELECTRICAL) THAT INDUCES THE THRESHOLD RESPONSE NECESSARY FOR NERVE 'firing' OR SENDING AN IMPULSE ALONG A NEUROLOGICAL PATHWAY ORIGINATING ON THE SURFACE OF THE SCAN AND TRAVELING THRU (the skin) hence the term trans or across (transcutaneous) the skin.
