How can i trace an impulse through the myocardium?
You can trace an impulse through the myocardium by using various techniques such as electrocardiography (ECG), which records the electrical activity of the heart. Another method is by using invasive procedures like cardiac catheterization or electrophysiological studies, which can directly measure electrical activity within the heart. These methods help to visualize the propagation of the impulse through different regions of the myocardium.
What is the difference between impulse conduction and transmission?
Impulse conduction refers to passage of impulse within the same cell. Where as transmission as the name implies, is concerned about passage of impulses either chemical or electrical from one cell to another.
What is the membrane of a nerve cell is comprised of?
Its main function is to propagate the action potential (the 'impulse') along the length of the axon.
The depressant effect of alcohol does not interfere with the conduction of the electrical impulse of the heartbeat?
Although alcohol is a depressant that can slow down the central nervous system, including heart rate, it does not directly interfere with the conduction of the electrical impulse of the heartbeat. However, excessive alcohol consumption can lead to irregular heartbeats, known as arrhythmias, due to electrolyte imbalances and other metabolic factors. If someone experiences abnormal heart rhythms while drinking, they should seek medical help.
What is the impulse conduction through a reflex arc?
nociceptors and mechanoreceptors (respond to touch, temp and pain)
What portion of the cardiac conduction system passes the impulse across the myocardium of both ventricles?
The portion of the cardiac conduction system that passes the impulse across the myocardium of both ventricles is the Purkinje fibers. These fibers distribute the electrical impulse rapidly throughout the ventricular myocardium, ensuring coordinated and efficient contraction of the ventricles. This system allows for synchronized beating of the heart, critical for effective blood pumping.

Is the velocity of a nerve impulse greater than electrical conduction's?
yes
Can the depressant effect of alcohol interfere with the conduction of the electrical impulse of the heartbeat?
false

When does the human heart rest?
The electrical impulse reaches all the muscle tissue in the ventricles, and the ventricles contract. This electrical conduction pattern occurs approx. every 0.8 seconds.
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 tissue type functions in impulse conduction?
Nervous tissue functions in impulse conduction. It consists of neurons that transmit electrical signals or impulses throughout the body. The specialized structure of neurons, including dendrites, axons, and synapses, enables them to rapidly transmit information.
What is impulse conduction?
Party of nervous
What is impulse conduction is fastest in neurons?
Impulses that travel along myelinated neurons are the fastest.
The speed at which a neural impulse travels is increased when the axon is encased by an?
insulating layer called myelin sheath. This myelin sheath helps to speed up the conduction of electrical impulses along the axon by allowing the impulse to jump between nodes of Ranvier, known as saltatory conduction.
