Which hormone is primarily responsible for the 'fight or flight' response?

Epinephrine

Explanation

Epinephrine triggers the 'fight or flight' response by increasing heart rate and blood pressure.

What is the name of the stress hormone released by the adrenal glands?

Adrenaline

Explanation

Adrenaline, also known as epinephrine, is released in response to stress, increasing heart rate and energy.

Which hormone regulates the sleep-wake cycle and can be affected by stress?

Melatonin

Explanation

Melatonin governs the sleep-wake cycle and can be disrupted by stress, affecting sleep patterns.

Which organ is primarily responsible for the production of cortisol?

Adrenal glands

Explanation

The adrenal glands, situated atop the kidneys, produce and release cortisol in response to stress.

Which gland produces the hormone oxytocin, which plays a role in social bonding and stress regulation?

Pituitary gland

Explanation

The pituitary gland secretes oxytocin, promoting social bonding and reducing stress levels.

Which part of the brain is crucial for regulating stress responses?

Hypothalamus

Explanation

The hypothalamus coordinates stress responses by releasing hormones that activate the adrenal glands.

What is the primary function of cortisol in the stress response?

To mobilize energy reserves

Explanation

Cortisol increases blood sugar levels to provide the body with immediate energy during stress.

Which of the following is NOT a physiological response to stress?

Decreased blood glucose levels

Explanation

Stress typically elevates blood glucose levels to provide energy for the body's response.

Which system of the body is responsible for the long-term stress response?

Endocrine system

Explanation

The endocrine system regulates long-term stress responses through hormone release.

#10

Which neurotransmitter is associated with relaxation and reduced stress?

GABA

Explanation

Gamma-aminobutyric acid (GABA) inhibits nerve transmission, promoting relaxation and reducing stress.

#11

What is the term for the body's ability to resist the damaging effects of stress?

Allostasis

Explanation

Allostasis refers to the body's ability to maintain stability through change, adapting to stressors.

#12

Which part of the brain plays a key role in interpreting and evaluating potential stressors?

Prefrontal cortex

Explanation

The prefrontal cortex assesses stressors, regulating emotional responses and decision-making.

#13

Which neurotransmitter is associated with the regulation of mood and can be influenced by chronic stress?

Serotonin

Explanation

Serotonin regulates mood and emotional stability, with chronic stress often depleting serotonin levels.

#14

What is the term for the phenomenon where exposure to a moderate level of stress can enhance performance?

Eustress

Explanation

Eustress refers to positive stress that motivates and enhances performance without causing harm.

#15

What is the term for the physiological changes that occur during the stress response?

Sympathetic arousal

Explanation

Sympathetic arousal involves physiological changes such as increased heart rate and respiration during stress.
