What is cerebral electrical stimulation?
cerebral electrical stimulation(CES).is a modification of Transcutaneous Electrical Nerve Stimulation (TENS). a low voltage signal applied to the body through the skin with the goal of replacing painful impressions with a massage-like sensation.
WhAT is an open space within a building called?
Atrium? plural: atria
What causes calcium ions to enter the synaptic bulb?
The nerve signal arrives at a synaptic knob and causes calcium channels to open. This allows the calcium ions to enter the synaptic knob. Calcium ions entry into the synaptic knob triggers exocytosis of synaptic vesicles, which release acetylcholine into the synaptic cleft.
Why does lightning come first?
Lightning comes first cause there is a discrepancy between areas of air between regions of warm and cold and this causes frictionals forces to build up,which sometimes create an electrical spark which is lightning.
Is plasma a gas with an electrical charge?
Yes, a plasma is a gas with an electrical charge.
What does an electrical signal cause the atria to do?
kn mn
What causes airbag deployment?
an electrical signal up to the airbag and it deploys
The p wave of the electrocardiogram is a signal from?
The P wave on ECG corresponds to electrical depolarization of the atria. It should be positive in lead II and negative in aVR when the P wave originates in the sinoatrial node.
Structure that carries the heart electrical impulse into the ventricle?
The atrioventricular (AV) node sends the signal to the AV bundle, where the wave of contraction travels from the atria to the ventricles.
What node triggers an im pulse that causes both atria to?
the atriventriculart node causes both atria to contract
When is an impulse an electrical signal?
When a stimulus causes positively charged ions to diffuse into the neuron.
Where is the electrical conduction of the atria located?
Purkinje fibers
What two components of the conduction system constitute the only electrical link between the atria and the ventricles?
The atrioventricular node and the bundle of HIS are the electrical conduction link between the atria and the ventricles.
What Node that triggers an impulse that causes both atria?
The Sinoatrial Node sends a wave of electric impulses through the heart, which causes both atria to contract.
What signal is the electrical equivalent of message signal?
Modulating Signal,
Does the fibrous skeleton of the heart serves as electrical insulation between the atria and the ventricles?
Yesh.
How audio signal convert into electrical signal?
microphone............
