All Free Psychology MCQs with Answers

• A. visual, tactile, kinetic and auditory only
• B. olfactory and kinetic only
• C. kinetic and auditory only
• D. all sensory systems

Explanation: Afferent pathways carry sensory information toward the central nervous system, so they participate in every sensory system, including…

• A. adrenal medulla, epinephrine
• B. adrenal cortex, carbohydrate
• C. pituitary, somatotropin
• D. pancreas, insulin

Explanation: Diabetes commonly involves insufficient insulin production or ineffective insulin action; insulin is produced by the pancreas and…

• A. electrical and chemical
• B. spontaneous and stimulated
• C. hormonal and mechanical
• D. chemical and hormonal

Explanation: An action potential involves electrical changes in the neuron's membrane and accompanying chemical changes involving ion movement across…

• A. Alzheimer's
• B. Parkinson's
• C. Schizophrenia
• D. Down's syndrome

Explanation: Alzheimer's disease is associated with loss of cholinergic neurons and reduced acetylcholine activity, especially in memory-related brain…

• A. partial lobe
• B. cerebellum
• C. pons
• D. thalamus

Explanation: The thalamus is the major relay station that routes most sensory information toward the cerebral cortex.

• A. medulla
• B. pons
• C. midbrain
• D. corpus collosum

Explanation: The medulla, pons, and midbrain are the principal divisions of the brainstem.

• A. right cerebral hemisphere
• B. left cerebral hemisphere
• C. regular formation
• D. corpus collosum

Explanation: Language functions are usually lateralized to the left cerebral hemisphere, including Broca’s and Wernicke’s areas.

• A. TSH (thyroid stimulating hormone)
• B. ACTH (adrenocorticotrophic hormone)
• C. FSH (follicle stimulating hormone)
• D. all of the above

Explanation: The anterior pituitary releases TSH, ACTH, and FSH, among other hormones.

• A. temporal lobe
• B. parietal lobe
• C. frontal lobe
• D. none of these

Explanation: The occipital lobe lies at the posterior part of the cerebral cortex and is mainly involved in visual processing.

• A. understanding, production
• B. comprehension, formulation
• C. organizing, production
• D. production, comprehension

Explanation: Broca’s area is primarily involved in producing or organizing speech, whereas Wernicke’s area is associated with understanding language.

• A. agnosia
• B. apraxia
• C. aphasia
• D. hyperphagia

Explanation: The ventromedial hypothalamus is commonly described as a satiety centre.

• A. pons
• B. cerebral cortex
• C. hypothalamus
• D. midbrain

Explanation: The hypothalamus controls the pituitary through releasing and inhibiting hormones and through neural control of the posterior pituitary.

• A. rerouting of nerve impulses
• B. slower never conduction times
• C. cortical brain lesions
• D. faster never conduction times

Explanation: Myelin insulates axons and permits rapid saltatory conduction between nodes.

• A. sympathetic nervous system
• B. the para-sympathetic nervous system
• C. cerebral cortex
• D. corpus collosum

Explanation: The sympathetic nervous system activates the body for fight or flight by increasing heart rate, breathing, and alertness.

• A. nerve fiber pathways
• B. cell bodies
• C. cell centers
• D. cortical issue

Explanation: White matter consists mainly of myelinated nerve-fibre pathways, whose myelin gives the tissue its pale appearance.

• A. MRI
• B. CAT system
• C. EEG
• D. ECT

Explanation: An EEG records the brain's electrical activity through electrodes placed on the scalp, including changes in electrical potentials.

• A. visual processing
• B. auditory processing
• C. long-term planning
• D. spatial processing

Explanation: The parietal lobe integrates bodily sensations and is especially important for spatial awareness and judging the location of objects.

• A. frontal lobe
• B. pineal gland
• C. olfactory bulbs
• D. parietal lobe

Explanation: Odour information first reaches the olfactory bulbs, which receive signals from receptors in the nose and relay them to olfactory brain…

• A. frontal
• B. cerebellum
• C. reticular activating system
• D. brain stem

Explanation: The reticular activating system is a network involved in arousal and alertness, not one of the major anatomical divisions of the brain.

• A. pons
• B. hypothalamus
• C. thalamus
• D. midbrain

Explanation: The pons helps regulate breathing by coordinating respiratory signals with the medulla.
