Sentences with phrase «sending electrical impulses»

The nervous system can make very quick changes in a fraction of a second by sending electrical impulses through the spinal cord to the muscles, or it can make slow changes by sending chemical messengers, called hormones, into the blood to reach the tissues and the organs.

When a nerve cell is activated, it sends an electrical impulse down its axon to the terminal, which stimulates a vesicle within the terminal to migrate to the terminal's surrounding membrane.

Because nerve cells, which send electrical impulses and neurotransmitters (think serotonin and dopamine), are rich in DHA, omega - 3s protect nerve cells from damage and indemnify normal, healthy communication between brain cells and the body's nerves, which can impact mood and ha been linked to depression severity.

This electrical current stimulates the brain cells (neurons) in a targeted brain area and causes them to fire (or send an electrical impulse).

The alveoli in the lungs are literally «drowning» and this sends electrical impulses to the brain to initiate the cough mechanism in an effort to remove the «fluid».

Not exact matches

In 2004, surgeons placed a tiny 100 - electrode array in his primary motor cortex, the brain region that controls voluntary movement, to collect electrical impulses from nerve cells and send them to a series of signal processors.

In people with these conditions the retina's photoreceptors — which transform light hitting the eye into electrical impulses — are often damaged, preventing visual information from being sent to the brain.

Action potentials, also known as nerve impulses, are electrical messages sent from our brains to other organs and muscles; for instance, nerves in the brain transmit action potentials through neural networks to direct our arm muscles to contract in order to call into action our hands to lift or hold an item, a primary research focus at the Columbia Motor Neuron Center, to which both the Zhang and Wichterle labs are affiliated.

Researchers discovered a gene also found in humans helps zebrafish convert water motion into electrical impulses that are sent to the brain for perception.

These nerve cells, known as retinal ganglion cells (RGCs), use electrical impulses to send visual information — entering the eye through the optic nerve — to the brain where images are perceived.

The macula is densely packed with photoreceptor cells called rods and cones that react to light and send electrical nerve impulses to the optic nerve and into the brain.

Regardless of the machine, the devices work by sending tiny electrical impulses through the body and measuring how quickly those impulses return.

As the subjects were doing the exercises, researchers measured their muscle activity using electrodes that detect the electrical impulses sent to the muscle (which is, put simply, a way to measure how hard a muscle is working).

It also helps your nerves send the small electrical impulses required for nerve function, and it contributes to blood vessel function.

Instead of the SA node (the «spark plug») starting and coordinating the electrical signal, many areas within the atria send out electrical impulses in a rapid, disorganized manner.

Since these electrical impulses are generated in the neurons and are sent straight to target organs, the abnormal, uncontrollable, and uncoordinated firing of nerve impulses can be readily seen in the said organs.

During a seizure, tiny areas of your pet's brain begin sending out electrical impulses that are received by the nerve cells that adjoin them.

During an epileptic seizure random electrical impulses are sent from the nerve cells of your pet's brain to muscles throughout its body.

Gunnar Davis is a heavy weapons specialist with an assault rifle as a primary weapon and a pistol for a secondary weapon, while his special abilities include Shockwave which sends a powerful electrical impulse that knocks down enemies; Stasis projects a stasis field that stops time for enemies albeit while simultaneously protecting them from incoming fire, but could still be useful to strategically change position, finding cover or running past a large group of enemies; Barrier creates a protective energy bubble that prevents damage from being received by Gunnar; and Storm hits enemies with a lightning strike.
