What stress hormone is associated with chronic stress, resulting in detrimental effects like decreased bone density, GI issues, headaches, and systemic inflammation when released for lengthy periods of time?

What stress hormones are secreted during episodes of acute stress, resulting in vasoconstriction, increases in HR, CO, BP, and blood glucose, as well as increased alertness (select all that apply)?

Which of the following criteria is required for a diagnosis of PTSD (select all that apply)?

T or F:

The conduction sequence of the heart is as follows: AV node -> SA node -> Purkinje Fibers -> Bundle of His.

This structure is considered to be the "pacemaker" of the heart as it generates the heart's electrical signal, typically beating 60-100 bpm.

What portion of an EKG represents depolarization, or contraction, of the ventricles?

In this heart rhythm, everything is "doing what it should be doing" and is considered normal and healthy.

In this heart rhythm, the ventricles are quickly contracting but the atria are not. Due to this, the organs of the body are not being perfused. This rhythm is considered lethal and can lead to ventricular fibrillation if not corrected.

In this heart rhythm, the heart has completely stopped beating and no electrical activity is present. It is sometimes referred to as a "flat line."
