What else can I help you with?
Does antegrade flow produce positive complex?
Yes, antegrade flow produces positive complex because it represents forward or normal flow of blood in an electrocardiogram (ECG). Positive complexes indicate depolarization traveling in the expected direction through the heart.
A wave of depolarization moves down the neuron?
A wave of depolarization occurs when there is a sudden influx of positive ions, typically sodium ions, into the neuron, leading to a reversal of the cell's membrane potential. This helps in transmitting electrical signals along the neuron through a process known as action potential propagation.
The opposition to current is called?
It is nothing but giving current in opposite direction (positive to negative andnegative to positive)
What current that does not reverse its direction of flow?
Direct current (DC) does not reverse its direction of flow. This means that the flow of electrical charge in a DC circuit always moves in one direction, from the positive terminal to the negative terminal.
What direction do the electrical charges flow?
Electrical charges flow from areas of higher potential (voltage) to areas of lower potential. This means that they flow from the positive terminal of a battery to the negative terminal in a closed circuit.
What does depolarization of the heart mean?
It is a positive wave in the hearts muscle cells, the process of electrical discharge and the flow of electrical activity.
What does the electrical charge on the inside of the axon become when depolarization occurs?
During depolarization, sodium ions rush into the axon, making the inside negative, and the outside positive.
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.
What are the major positive electrolytes responsible for depolarization?
The major positive electrolytes responsible for depolarization of a cell are sodium (Na+) and calcium (Ca2+). These ions enter the cell during the depolarization phase of an action potential, leading to a change in membrane potential and initiation of an electrical signal.
When a positive charge is applied to the inside of an axon what is the effect is called?
When a positive charge is applied to the inside of an axon, it creates a depolarization event known as an action potential. This change in electrical charge triggers the propagation of an electrical signal along the axon, allowing for the transmission of information within the nervous system.
What is the direction of electrical current flow?
Negative to positive.
What is depolorization?
Depolarization is a change in a cell's membrane potential, making it more positive, or less negative. In neurons and some other cells, a large enough depolarization may result in an action potential.
The greater influx of sodium ions results in what of the membrane?
The greater influx of sodium ions results in membrane depolarization. This is because sodium ions carry a positive charge, which leads to a decrease in the membrane potential towards zero or a positive value.
How is the electrical charge inside the neuron?
Neurons send messages electrochemically and all chemicals in the body are electrically-charged. When neurons inside the body are electrically-charged, they are called ions. When a neuron is at rest, or not electrically-charged, the inside is negative and the outside is positive.
Does antegrade flow produce positive complex?
Yes, antegrade flow produces positive complex because it represents forward or normal flow of blood in an electrocardiogram (ECG). Positive complexes indicate depolarization traveling in the expected direction through the heart.
A wave of depolarization moves down the neuron?
A wave of depolarization occurs when there is a sudden influx of positive ions, typically sodium ions, into the neuron, leading to a reversal of the cell's membrane potential. This helps in transmitting electrical signals along the neuron through a process known as action potential propagation.
What is the rapid change in a membreanes potential cause by the depolarization of a neuron?
The rapid change in membrane potential caused by the depolarization of a neuron is known as an action potential. During depolarization, voltage-gated sodium channels open, allowing sodium ions to flow into the cell, causing the inside of the neuron to become more positive. This shift in charge initiates the action potential, which is essential for the transmission of electrical signals along the neuron.
