1Which division of the human nervous system is responsible for initiating the fight-or-flight response during an acute threat?
A.Sympathetic nervous system
B.Parasympathetic nervous system
C.Somatic nervous system
D.Central nervous system
Explanation: The sympathetic nervous system is a branch of the autonomic nervous system that activates physiological arousal (increased heart rate, pupil dilation, inhibition of digestion) in response to stress or perceived danger.
2Which lobe of the cerebral cortex contains the primary somatosensory cortex responsible for processing tactile sensations such as touch, temperature, and pain?
A.Parietal lobe
B.Frontal lobe
C.Occipital lobe
D.Temporal lobe
Explanation: The parietal lobe, located behind the frontal lobe, houses the primary somatosensory cortex which receives and processes bodily sensations including touch, pressure, temperature, and pain.
3What primary function is carried out by the myelin sheath surrounding a neuronal axon?
A.Insulating the axon to speed up neural impulse transmission
B.Synthesizing neurotransmitters for release into the synaptic cleft
C.Receiving incoming chemical signals from adjacent presynaptic neurons
D.Anchoring the neuron to surrounding glial cells in the cerebral cortex
Explanation: The myelin sheath is a fatty layer of tissue that wraps around the axons of many neurons. It insulates the electrical signal, enabling saltatory conduction across the nodes of Ranvier, which significantly increases signal transmission speed.
4Which brain structure acts as a relay station, receiving incoming sensory information (except smell) and routing it to the appropriate regions of the cerebral cortex?
A.Thalamus
B.Hypothalamus
C.Amygdala
D.Cerebellum
Explanation: The thalamus is situated at the top of the brainstem and functions as the primary sensory relay station, directing signals for vision, hearing, touch, and taste to their respective cortical destinations.
5During deep Stage 3 NREM sleep, which EEG brainwave pattern predominates in a healthy adult?
A.Delta waves
B.Beta waves
C.Alpha waves
D.Theta waves
Explanation: Stage 3 NREM (slow-wave sleep) is characterized by high-amplitude, low-frequency delta waves (0.5–4 Hz), indicating deep, restorative physical sleep.
6Which area of the left temporal lobe is primarily responsible for language comprehension and constructing meaningful speech?
A.Wernicke's area
B.Broca's area
C.Primary motor cortex
D.Prefrontal cortex
Explanation: Wernicke's area, located in the left temporal lobe, is crucial for understanding spoken and written language. Damage results in receptive aphasia, where speech remains fluent but lacks meaningful content.
7Which major inhibitory neurotransmitter in the central nervous system works to reduce neuronal excitability and prevent overstimulation?
A.GABA (Gamma-aminobutyric acid)
B.Glutamate
C.Dopamine
D.Acetylcholine
Explanation: GABA is the chief inhibitory neurotransmitter in the human brain. It hyperpolarizes postsynaptic membranes, making neurons less likely to fire an action potential and promoting calming/inhibitory effects.
8What is the role of the hormone melatonin in human biological rhythms?
A.Regulating the sleep-wake cycle by signaling darkness and promoting sleep onset
B.Increasing blood glucose levels during acute muscular exertion
C.Stimulating muscle repair and protein synthesis during heavy physical training
D.Triggering the immediate release of adrenaline during environmental danger
Explanation: Melatonin is secreted by the pineal gland in response to decreasing light levels (monitored via the suprachiasmatic nucleus), helping to regulate circadian rhythms and induce sleepiness.
9A patient suffered a head injury and can understand spoken sentences but struggles to produce fluent speech, uttering slow, labored words. Which region was most likely damaged?
A.Broca's area in the frontal lobe
B.Wernicke's area in the temporal lobe
C.Primary visual cortex in the occipital lobe
D.Somatosensory cortex in the parietal lobe
Explanation: Broca's area, situated in the left frontal lobe, governs expressive speech production. Injury leads to Broca's (expressive) aphasia, where comprehension is intact but speech production is slow, fragmented, and deliberate.
10How does the hypothalamic-pituitary-adrenal (HPA) axis differ from the sympathetic-adreno-medullary (SAM) pathway during stress exposure?
A.The HPA axis releases cortisol for sustained energy management, while the SAM pathway releases adrenaline for rapid emergency response
B.The HPA axis operates instantaneously via electrical nerve fibers, whereas the SAM pathway relies exclusively on slow pituitary hormonal transport
C.The HPA axis lowers blood pressure and heart rate, whereas the SAM pathway elevates body temperature and digestion
D.The HPA axis is activated only during pleasant excitement, whereas the SAM pathway responds exclusively to traumatic distress
Explanation: The SAM pathway is an immediate neuro-endocrine response that secretes catecholamines (adrenaline/noradrenaline) for rapid fight-or-flight actions. The HPA axis is a slower neurohormonal cascade ending in adrenal cortex secretion of cortisol, maintaining energy mobilization during chronic stress.
