Fear Affecting the Brain

How is fear a useful part of a person’s survival mechanism?

• Fear keeps us safe and without the fear response, people could walk into harm’s way and face serious danger.

• Fear makes a person's blood pressure rise.

• Fear keeps us from enjoying every day activities.

• Fear, if not treated, can become a phobia.

How does the “fight or flight” reaction work in the body?

• The 'fight or flight" reaction causes a person to develop a phobia.

• The "fight or flight" reaction creates memories.

• When faced with a threat, hormones are released, allowing the body to address the threat faced; which causes a person to either stay and fight or run away seeking safety.

• The "fight or flight" reaction can cause confusion in a person.

Which two sentences below are part of the body’s fear response according to the video?

• Sensory organs send information to the hypothalamus.

• The hypothalamus floods the body with adrenaline.

• A false alarm tells the brain to run away.

• The left side of the brain sends signals to the right side.

• The amygdala activates the freeze response.

The video shows how the threat alert helps the hippocampus, prefrontal cortex, and amygdala to —

• alert the body to stay still and freeze

• control the fight or flight response

• create a memory of the experience

• tell the body when to relax

The amygdala is also known as —

• the prefrontal cortex

• the creator of adrenaline

• the brain’s threat center

• the fight or flight response

According to the video, cells called neurons do what job in the fear response?

• They alert the amygdala that it needs to wake up.

• They tell your body when to produce adrenaline.

• They pass information between the brain and body.

• They tell your body when something dangerous is close.

The model of the brain in the video helps the viewer understand —

• the way the amygdala connects to the thalamus

• the role the amygdala plays as the brain’s threat center

• the role the hippocampus plays in the brain

• the way that the body recognizes a false alarm

The main purpose of the video is to —

• describe the role of the amygdala in the body’s fear response

• explain how the frontal cortex interacts with the amygdala

• teach us the function of the hippocampus in the brain

• explain the purpose of adrenaline in the fight or flight reaction

If something that first appeared as a threat turns out to be a false alarm, what can the body do?

• Run

• Relax

• Freeze

• Remember

Which of the following best describes the way the video portrays a person encountering a threat?

• A man on a hike gets scared and runs away.

• A model of the brain shows how the amygdala works.

• A picture of the thalamus shows how it connects to the frontal cortex.

• A man on a hike suddenly sees a snake in his path.
