1: What separates the frontal lobe from the parietal lobe?
Correct Answer: Central sulcus
1. Central sulcus divides frontal (anterior) from parietal (posterior) lobes.
2. Precentral gyrus (motor) in front; postcentral gyrus (sensory) behind.
3. Key landmark for motor/sensory strip localization.
2: Which lobe is associated with object identification and auditory signals?
Correct Answer: Temporal lobe
1. Temporal lobe processes auditory information and object recognition.
2. Wernicke's area (language comprehension) located in dominant temporal lobe.
3. Hippocampus (memory) within temporal lobe.
3: Which part of a neuron receives the signal?
A. Axon
B. Axon Terminal
C. Dendrites
D. Soma
Correct Answer: C. Dendrites
1. Dendrites receive neurotransmitters from presynaptic neuron.
2. Signal travels dendrite → soma → axon → axon terminal.
3. Dendritic spines are sites of excitatory synapses.
, 4: Which area of the brain is associated with emotional regulation and perception of odors?
A. Amygdala
B. Basal ganglia
C. Prefrontal cortex
D. Wernicke's area
Correct Answer: A. Amygdala
1. Amygdala processes fear, anxiety, and emotional salience.
2. Olfactory cortex adjacent; smell strongly linked to emotion.
3. Hyperactivity in anxiety disorders.
5: Which neurotransmitter is considered the chief inhibitory neurotransmitter?
A. Serotonin
B. Histamine
C. Glutamate
D. GABA
Correct Answer: D. GABA (gamma-aminobutyric acid)
1. GABA is the primary inhibitory neurotransmitter in CNS.
2. Benzodiazepines and barbiturates enhance GABA-A receptor function.
3. Low GABA linked to anxiety, seizures, insomnia.
6: A client has elevated levels of which neurotransmitter if they present with anxiety, feeling frozen
in place, tachycardia, and difficulty sleeping?
A. Serotonin
B. GABA
C. Norepinephrine
D. Dopamine
Correct Answer: C. Norepinephrine
1. Norepinephrine regulates fight-or-flight response.
2. Elevated NE linked to anxiety, panic, hyperarousal.
3. Beta-blockers reduce somatic symptoms of anxiety.
7: SSRIs, SNRIs, and tricyclic antidepressants increase levels of which neurotransmitter?
A. Dopamine
B. Serotonin
C. GABA
D. Glutamate
Correct Answer: B. Serotonin (5-HT)
1. SSRIs block serotonin reuptake; SNRIs block serotonin and norepinephrine reuptake.
2. TCAs block serotonin and norepinephrine reuptake (plus other receptors).
3. Increased serotonin improves mood, anxiety, and OCD symptoms.
