That specific vein which is large and superficial that are located on each side of the neck is called the common carotid artery. In addition, the main function of this type of artery is to let the oxygenated blood flow through our head through the neck. This artery can be easily be felt by placing our fingers on it.

Answer:
The best answer to the question, would be: The reaction that is now generated in Steve whenever he enters his AP History class as now he associates it not with fear, stress and insecurity, but rather, with good feelings and a sense of empowerment.
Explanation:
Classical conditioning is a theory in psychology that attempts to explain how human beings adapt and respond to their environment. Classical conditioning has become best known for the "Little Albert" experiment, in which a child was exposed to a series of stimulus to condition his fear response. As the stimuli were presented in succession, accompanied by a second stimulus that generated fear, it was seen that little Albert now associated, and responded, to similar stimulus as the ones that generated fear, without having to be prepared for it. The response had been conditioned into him. In the case of Steve, the process is almost the same, but the response that becomes ingrained in him is a positive one. He first fears his AP class because he does not have the conditions the others do. However, the positive remarks, and constant praise from the teacher, finally transforms Steve´s reaction of fear into one of security and comfort and in the end, now he does not need his teacher to say anything; he already feels secure in his class because he has associated his teacher´s praise with the class itself.
The SA Node is the heart's normal pacemaker. When the SA Node depolarizes, electrical signal spreads through the atrial muscle causing contraction.
Explanation:
Inherent rhythmicity / automaticity - The property of the pacemaker cells of the heart to start electrical sequence of depolarization and repolarization.
SA Node or Sino-atrial Node generates the electrical signal.
The electrical signal passes through internodal pathways, atrial fibres, atrioventricular node (AV Node), the bundle of His, Purkinje fibres, right bundle branch, left bundle branch.
Systole - Contraction of cells when the electrical signal of depolarization reaches the contractile cells.
Diastole - Relaxation of cells when the electrical signal of repolarization reaches the myocardial cells.
