When a person is anxious or fearful, the autonomic nervous system shunts blood away from peripheral veins to the core of the body - TRUE

  • Sympathetic stimulation of blood vessels causes arteries and arterioles (resistance vessels) to constrict, increasing vascular resistance and reducing distal blood flow.
  • The increased vascular resistance that results from this across the body raises arterial pressure.
  • When our bodies shift into superman mode, the second signal is transmitted to the hypothalamus, where it activates our autonomic nerve system,
  • which is in charge of the fight-or-flight impulse.
  • Our bodies receive an adrenaline boost as well as an increase in heart rate and blood pressure. When you are afraid, you get that rush.
