A group of heart muscles that specialize in conducting electric to transfer this impulses to the apex point of fascicular branches from the AV node, is known as HIS bundles. It is located in the "right and left branches" in the interventricular septum.
The filament fibres produced by the branches transports the impulse to the muscles of ventricular to make it contract. It takes a time period of 0.03-0.04 seconds for the impulses to flow to the ventricular.
The blunde of His is an agruppation of neurons that are localized on the ventrical walls of the heart. It's mision is to transmit the nervous signals that come from the sinoatrial node that is located on the left atria of the heart, to the muscles that form the vertix of this organ, making them contract.
The answer is C: a collection of heart muscle component specializing in electrical conduction that allow the ventricles to contract.
While doing upper-body exercise routine, fatigue of target muscles can be safely achieved within<span> the short time-frame of about 1.5 minutes (the time-frame for anaerobic pathways) by simply performing 8 to 12 </span>repetitions<span> at a moderate movement speed.</span>
When you exercise, your body releases chemicals called endorphins. These endorphins interact with the receptors in your brain that reduce your perception of pain. Endorphins also trigger a positive feeling in the body, similar to that of morphine.
