Free General Psychology MCQs with Answers

• A. medulla oblongata
• B. hippocampus
• C. hypothalamus
• D. thalamus

Explanation: The hypothalamus regulates biological drives such as hunger, eating and satiety, along with temperature and endocrine functions.

• A. axon terminals
• B. dendrites
• C. glia
• D. action potentials

Explanation: Axon terminals release neurotransmitters into the synapse, allowing a neuron to communicate with a receiving cell.

• A. neurotransmitters
• B. plasmas
• C. syntactic structures
• D. adrenocorticoids

Explanation: Neurotransmitters are chemicals released by neurons that cross synapses and influence receiving cells.

• A. interneurons
• B. motor neurons
• C. sensory neurons
• D. neurotransmittersTry Nootropic Supplements

Explanation: Interneurons make up the vast majority of neurons and link sensory and motor neurons within the central nervous system.

• A. nerves
• B. synapses
• C. neurotransmitters
• D. action potential

Explanation: Neurotransmitters are chemical messengers released by neurons to communicate across synapses, much as hormones carry signals through the…

• A. the cerebellum
• B. the gonads
• C. the thyroid gland
• D. the adrenal medulla

Explanation: Excess secretion of thyroid hormones increases metabolic activity and can produce nervousness, restlessness, and hyperactivity.

• 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.
