Understanding the Stress Response System

The video explores the human stress response, starting with a scenario of being home alone and hearing a knock at the door. It explains the arrest and orient system, the brain's role in stress, and the functions of the thalamus and amygdala. The video also covers physical responses to stress, such as increased heart rate and blood pressure, and discusses the long-term effects of chronic stress on health.

What is the initial reaction of the body when it encounters an unexpected situation?

• Fight or flight response

• Arrest and orient response

• Relaxation response

• Freeze response

How long has the stress response system been developing in humans?

• 500 million years

• 300 million years

• 100 million years

• 50 million years

Which part of the brain is primarily responsible for detecting threats?

• Thalamus

• Hippocampus

• Cortex

• Cerebellum

What role does the amygdala play in the stress response?

• Manages memory storage

• Processes emotional experiences and detects threats

• Controls voluntary movements

• Regulates digestion

What happens to blood pressure during a stress response?

• It decreases

• It remains the same

• It increases

• It fluctuates randomly

Why does the body release more glucose during stress?

• To store energy for later

• To aid in digestion

• To provide immediate energy for action

• To reduce blood sugar levels

What is the purpose of increased sweating during stress?

• To increase body temperature

• To hydrate the skin

• To cool down the body

• To eliminate toxins

What is a potential long-term effect of chronic stress?

• Improved immune function

• Enhanced memory

• Increased energy levels

• Development of chronic diseases

How does chronic stress affect the immune system over time?

• It weakens it

• It strengthens it

• It has no effect

• It makes it more efficient

What is the main function of the stress response?

• To cause anxiety

• To prepare the body for action

• To induce relaxation

• To slow down metabolism
