How do you convert electrical impulse in to electrical energy?
if it acts on a charged particle
When is an impulse an electrical signal?
When a stimulus causes positively charged ions to diffuse into the neuron.
How are hormones similar to neurotransmitters?
A neural impulse is similar to an electrical signal in three ways: 1. there are electrical voltages involved in the movement of the neural impulse; 2. an electrical signal can convey information, as can a neural impulse; 3. an electrical signal can cause an action, like a car starter switch starting the engine, and a neural impulse can cause a muscle to contract to move a limb. (note that with respect to the voltages involved in the neural impulse, the voltages are created by the movement of chemicals, charged particles called ions, somewhat similar to how batteries produce voltages.) (also note that the neural impulse is the signal which moves along the axon, as an action potential.)
Describe the path a nerve impulse travels through?
When an impulse travels to the brain, it is first received by sensory receptors, then sent through the neurons by an electrical current. When the neuron receives the signal from a sensory receptor or from another neuron, the nucleus processes the impulse and then sends it down the axon. When a neuron is resting, the inside of the cell has a negative charge caused by active transport of NA and K molecules. This is called the resting potential. When the impulse hits the axon, the electricity causes NA pumps to open, allowing a flow of positively charged the molecule into the cell, causing the charges to switch. This is called the action potential. As the impulse passes, the K pumps open, restoring the original charge. When the impulse reached the end of the axon, neurotransmitters chemically pass the impulse to the next neuron. ;
What are the factors involved in the transmission of a nerve impulse?
action potational. volage change, threshold etc
In coronary conduction the electrical impulse is released at what level of the coronary electrical system?
With Wolff-Parkinson-White Syndrome, the heart has an extra nerve, or "accessory pathway" that electrically connects the _____ to the _____.
What does it mean when an object is electrically polarized?
Before an impulse is received, a resting neuron is polarized with different charges on either side of the cell membrane. The exterior of the cell is positively charged with a larger number ofsodium ions present compared to the interior of the cell. The interior of the cell is negatively charged since it contains more potassium ions than the exterior of the cell. As a result of the differences in charges, an electro-chemical difference of about -70 millivolts occurs.IT means that electrical charges on the outside of the membrane is positive while inside is negative
You could locate sites involved in transmitting a nerve impulse by finding the?
You could locate sites involved in transmitting a nerve impulse by finding the synapses. They are defined as a junction between two nerve cells, consisting of a minute gap across which impulses pass by diffusion of a neurotransmitter.
You could locate receptor sites involved in transmiting a nerve impulse by finding the?
Synapse? Dendrite? Dendritic spine? Or, "You could maybe a better answer to your question get if you re-stated it less confusingly as?" ie, perhaps, "Where are the receptor sites involved in transmitting a nerve impulse LOCATED?"
What two minerals are involved in nerve impulse and conduction?
Not minerals, it is ions. Calcium ions and sodium ions.
What is meaningful sentence of impulse?
impulse is impulse
How do frontal lobe injuries affect personality?
Usually a person with a frontal lobe injury has very little impulse control, they tend to be more emotionally charged.
