Correct answer is: 1970s
Q.6 Which immune cells are directly affected by stress hormones like cortisol?
Red blood cells
T-lymphocytes
Platelets
Epithelial cells
Explanation - T-lymphocytes, essential for adaptive immunity, can be suppressed by elevated cortisol levels during stress.
Correct answer is: T-lymphocytes
Q.7 Which psychological factor is most likely to enhance immune function?
Positive emotions
Chronic worry
Sleep deprivation
Isolation
Explanation - Positive emotions have been linked to stronger immune responses, while negative states like chronic stress impair immunity.
Correct answer is: Positive emotions
Q.8 Which physiological system is considered the mediator between psychological stress and immunity?
Endocrine system
Digestive system
Respiratory system
Muscular system
Explanation - The endocrine system releases hormones like cortisol that mediate the effects of psychological stress on the immune system.
Correct answer is: Endocrine system
Q.9 Which of the following is an example of a psychoneuroimmunological study?
Measuring antibody levels after exam stress
Tracking calories burned during exercise
Studying genetic inheritance of eye color
Analyzing rainfall patterns and mood
Explanation - This study examines how psychological stress (exam) influences immune function (antibody levels), a core psychoneuroimmunology concept.
Correct answer is: Measuring antibody levels after exam stress
Q.10 Which of the following best describes cytokines?
Proteins involved in immune signaling
Hormones controlling metabolism
Enzymes for digestion
Neurotransmitters for movement
Explanation - Cytokines are signaling proteins released by immune cells that communicate and regulate immunity and inflammation.
Correct answer is: Proteins involved in immune signaling
Q.11 Which mental health condition has been linked to altered immune responses?
Depression
Color blindness
Astigmatism
Dyslexia
Explanation - Depression is associated with increased inflammation and altered immune functioning, illustrating psychoneuroimmunology principles.
Correct answer is: Depression
Q.12 Which lifestyle factor can negatively influence both mood and immune function?
Chronic sleep deprivation
Regular meditation
Balanced diet
Moderate exercise
Explanation - Lack of sleep elevates stress hormones and weakens the immune system, increasing susceptibility to illness.
Correct answer is: Chronic sleep deprivation
Q.13 Which type of stress is more likely to suppress immune function?
Acute stress
Chronic stress
Eustress
Exercise-induced stress
Explanation - Long-term, chronic stress maintains high cortisol levels, which suppresses immune function over time.
Correct answer is: Chronic stress
Q.14 How can social support influence immune health?
By reducing stress and boosting immune response
By increasing caloric intake
By promoting vitamin deficiencies
By enhancing hair growth
Explanation - Social support lowers stress, reduces cortisol, and enhances immune functioning.
Correct answer is: By reducing stress and boosting immune response
Q.15 Which of these is a common method to assess immune function in psychoneuroimmunology research?
Measuring white blood cell count
Measuring heart rate only
Measuring IQ scores
Measuring skin pigmentation
Explanation - White blood cell counts and activity levels are common indicators of immune function in psychoneuroimmunology studies.
Correct answer is: Measuring white blood cell count
Q.16 Which area of the brain is heavily involved in stress responses affecting immunity?
Hypothalamus
Occipital lobe
Cerebellum
Medulla oblongata
Explanation - The hypothalamus activates the HPA axis during stress, which influences cortisol release and immune function.
Correct answer is: Hypothalamus
Q.17 Which term refers to beneficial stress that improves immune function?
Eustress
Distress
Hypostress
Hyperstress
Explanation - Eustress is positive stress that can enhance alertness and, in some cases, temporarily boost immune function.
Correct answer is: Eustress
Q.18 Which of these interventions has been shown to improve immune response in stressed individuals?
Mindfulness meditation
Prolonged isolation
High sugar diet

Explanation - Mindfulness and relaxation techniques reduce stress hormones and can strengthen immune function.
Correct answer is: Mindfulness meditation
Q.19 Which psychoneuroimmunology concept explains why stress worsens autoimmune conditions?
