Free General Psychology MCQs with Answers

• 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.

• A. serotonin
• B. endorphins
• C. dopamine
• D. insulin

Explanation: Insulin is primarily a hormone that regulates blood glucose, not a neurotransmitter used for rapid neuron-to-neuron signalling.

• A. pituitary gland
• B. parathyroid gland
• C. adrenal medulla
• D. parasympathetic nervous system

Explanation: The adrenal medulla releases adrenaline and noradrenaline during acute stress, preparing the body for fight or flight.

• A. at its resting potential
• B. in its absolute refractory period
• C. an afferent neuron
• D. in its relative refractory period

Explanation: The absolute refractory period is the brief interval after an action potential when voltage-gated sodium channels cannot be reactivated…

• A. a cell body
• B. septum
• C. myelin sheath
• D. dendrites

Explanation: A septum is a partitioning structure, not a standard part of a neuron. Neurons commonly have a cell body and dendrites, while myelin…

• A. synaptic reflex
• B. spastic movement
• C. monosynaptic reflex
• D. double innervations

Explanation: The knee-jerk response uses a single synapse between a sensory neuron and a motor neuron, making it a monosynaptic reflex.

• A. amygdala
• B. cerebellum
• C. thalamus
• D. medulla

Explanation: The amygdala helps regulate fear, aggression, and other emotional responses, so it is the structure most associated with pathological…

• A. thyroid
• B. adrenal
• C. pituitary
• D. pineal

Explanation: The pituitary is called the master gland because its hormones influence several other endocrine glands, including the thyroid, adrenals…

• A. Broca's area
• B. Nodes of Ranvier
• C. terminal buttons
• D. Wernicke's area

Explanation: Nodes of Ranvier are exposed gaps between sections of myelin, allowing the action potential to jump from node to node in saltatory…

• A. medulla
• B. midbrain
• C. cerebellum
• D. pons

Explanation: The medulla contains vital respiratory and cardiovascular control centers, so severe damage there can stop breathing.

• A. constriction of the pupils
• B. increased rate of digestion
• C. accelerated heart beat
• D. increased hormone production

Explanation: Adrenaline activates the sympathetic fight-or-flight response, which raises heart rate and redirects energy toward immediate action.

• A. ovaries
• B. testes
• C. pituitary gland
• D. hypothalamus

Explanation: Follicle-stimulating hormone is produced and released by the anterior pituitary, where it supports ovarian follicle development in females…

• A. afferent nerve, efferent nerve, neural modulator
• B. efferent nerve, interneuron, afferent nerve
• C. afferent nerve, interneuron, efferent nerve
• D. efferent nerve, afferent nerve, neural modulator

Explanation: Sensory information travels toward the central nervous system through an afferent neuron, is processed by an interneuron, and reaches…

• A. limbic activating system
• B. cerebral activating system
• C. reticular activating system
• D. thalamic activating system

Explanation: The reticular activating system in the brainstem regulates arousal and helps shift the brain from sleep to wakefulness.

• A. Johannes Muller
• B. Franz Gall
• C. William James
• D. Charles Sherrington

Explanation: Charles Sherrington is credited with inferring and naming the synapse, the junction through which neurons communicate.
