What are the electrical impulses in the heart that are relayed to the ventricles by what?
A junction box, also known as the AV node, is how electrical impulses in the heart are relayed to the ventricles. The ventricles help make the muscle contract and then pump the blood.
What carries electrical impulses across the heart and causes the ventricles contract?
SA node.
Phil has heart block His electrical impulses are being blocked from reaching the ventricles An electrical device that causes ventricular contractions at a rate necessary to maintain circulation is b?
The electrical device is a pace maker.
What is Wolff-Parkinson-White syndrome?
An abnormal, rapid heart rhythm, due to an extra pathway for the electrical impulses to travel from the atria to the ventricles.
Why electrical impulses are referred to as neural impulses?
Electrical impulses are referred to as neural impulses because a neural impulse cause electrical impulses. Neurons use electrical impulses to send messages.
How does the structure of a neuron reflect the function of transmitting messages or electrical signals?
the structure of the neutron allows for efficient transmission of electrical impulses in the body.
Are Nerve impulses electrical signaled?
Nerve impulses are electrical signals.
What is the precise amount of electrical pulses does the brain send the heart?
The brain does not send "electrical pulses" to the heart. Electrical impulses are actually generated within the heart itself (in the SA node), which travel through several intricate pathways from the atria down to the ventricles.
What is happening during a complete heart block?
Complete heart block is where the electrical impulses from the SA node of the heart cannot reach the ventricles along the normal pathway. Instead the atrial contract from the SA node singles and the ventricles contract from the ventricular cells
Why does the QRS complex have the largest amplitude?
More cells depolarize during this QRS complex(ventricular contraction). The reason is because the muscle mass of the atria is small compared with that of the ventricles. The ventricles have a larger muscle mass. Therfore the electrical impulses within the atria are shorter and are less. The ventricles are larger so there is a larger deflection of the ECG when the ventricles are depolarised this is called the QRS complex
What causes tinnitius?
Electrical impulses
What do electrical impulses of the brain cause?
Electrical impulses of the brain are the nervous impulses that the nervous system uses to control body functions. These impulses may be relayed within the brain, or may be carried to the peripheral nervous system.
