Domain: Biological Bases of Behavior
1. Which structure is most directly involved in processing the emotional significance of a threat?
A. Amygdala
B. Cerebellum
C. Occipital lobe
D. Medulla
Correct Answer: A
Rationale: The amygdala helps detect and evaluate emotionally salient stimuli, including threat-related cues.
2. Which brain structure is essential for forming new explicit memories?
A. Hypothalamus
B. Hippocampus
C. Pons
D. Pituitary gland
Correct Answer: B
Rationale: The hippocampus is crucial for consolidating new declarative, or explicit, memories.
3. What is the primary function of myelin around many axons?
A. Produce neurotransmitters
B. Speed neural impulse conduction
C. Receive sensory input
D. Regulate blood glucose
Correct Answer: B
Rationale: Myelin insulates axons and enables faster, more efficient impulse transmission.
4. Which division of the autonomic nervous system prepares the body for action during an
emergency?
PSYC 140 Psychology Exam Evaluation 2026/2027
, A. Parasympathetic
B. Somatic
C. Sympathetic
D. Enteric
Correct Answer: C
Rationale: The sympathetic division mobilizes the body for action by increasing arousal and directing
resources toward immediate demands.
5. A neuron is most likely to fire an action potential when:
A. Its membrane reaches threshold
B. It is at resting potential
C. Sodium channels are permanently closed
D. Neurotransmitters are absent
Correct Answer: A
Rationale: An action potential is triggered when summed input depolarizes the membrane to its threshold.
6. Which neurotransmitter is most closely associated with skeletal-muscle activation at the
neuromuscular junction?
A. Dopamine
B. Acetylcholine
C. Serotonin
D. GABA
Correct Answer: B
Rationale: Motor neurons release acetylcholine at the neuromuscular junction to initiate muscle contraction.
7. Damage to Broca’s area would most likely impair:
A. Producing fluent speech
B. Recognizing faces
C. Maintaining balance
D. Regulating sleep cycles
Correct Answer: A
Rationale: Broca’s area is strongly associated with speech production; injury often produces effortful,
nonfluent language.
8. Which lobe of the cerebral cortex is most directly responsible for processing visual information?
A. Frontal
B. Parietal
C. Temporal
D. Occipital
Correct Answer: D
Rationale: The occipital lobe contains primary visual cortex and is central to visual processing.
9. The endocrine system communicates primarily by releasing:
A. Hormones into the bloodstream
B. Electrical impulses through axons only
C. Enzymes into synapses
D. Myelin into ventricles
Correct Answer: A
Rationale: Endocrine glands secrete hormones into the blood, allowing signals to affect distant target tissues.
10. The corpus callosum principally connects:
A. The cerebellum and spinal cord
B. The two cerebral hemispheres
C. The thalamus and pituitary
D. The retina and optic nerve
Correct Answer: B
Rationale: The corpus callosum is a large fiber tract that enables communication between the cerebral
hemispheres.
11. Which brainstem structure is especially important for basic functions such as breathing and
heart rate?
A. Medulla
B. Hippocampus
C. Basal ganglia
D. Insula
