1. The central nervous system (CNS) is made up of which two main
components?
A) Brain and peripheral nervous system
B) Brain and spinal cord
C) Spinal cord and peripheral nervous system
D) Sensory and motor neurons
Answer: B) Brain and spinal cord
Rationale: The central nervous system consists of the brain and spinal cord.
The peripheral nervous system includes the network of nerves that connect the
CNS to the rest of the body .
2. Phineas Gage, the famous railroad construction worker who survived a
traumatic brain injury, experienced significant damage to which brain
structure?
A) Temporal lobe
B) Prefrontal cortex
,C) Occipital lobe
D) Medulla
Answer: B) Prefrontal cortex
Rationale: Phineas Gage's injury resulted in significant damage to his
prefrontal cortex, leading to dramatic personality changes and difficulties in
executive functions, decision-making, and emotional regulation. This case
provided early evidence for the role of the frontal lobes in personality and
social behavior .
3. The primary visual cortex is located in which part of the brain?
A) Temporal lobe
B) Occipital lobe
C) Parietal lobe
D) Frontal lobe
Answer: B) Occipital lobe
Rationale: The primary visual cortex, also known as V1, is located in the
occipital lobe at the rear of the brain and is responsible for initial visual
processing .
4. Damage to the Broca's area of the brain is most likely to result in:
A) Difficulty understanding spoken language
B) Difficulty producing speech
C) Impaired visual perception
D) Impaired motor coordination
Answer: B) Difficulty producing speech
,Rationale: Broca's area, located in the left frontal lobe, is responsible for the
production and articulation of speech. Damage to this area can lead to
expressive language disorders such as Broca's aphasia .
5. Which brain region is primarily associated with regulating emotions and
forming long-term memories?
A) Hippocampus
B) Prefrontal cortex
C) Amygdala
D) Cerebellum
Answer: C) Amygdala
Rationale: The amygdala plays a key role in the processing of emotions,
particularly fear, and the formation of emotional memories .
6. Damage to which area of the brain is most likely to result in impaired motor
coordination and balance?
A) Occipital lobe
B) Temporal lobe
C) Parietal lobe
D) Cerebellum
Answer: D) Cerebellum
Rationale: The cerebellum is responsible for coordinating voluntary
movements and maintaining balance and posture .
7. The primary inhibitory neurotransmitter in the central nervous system is:
A) Serotonin
, B) GABA
C) Glutamate
D) Dopamine
Answer: B) GABA
Rationale: Gamma-aminobutyric acid (GABA) is the main inhibitory
neurotransmitter in the central nervous system, playing a crucial role in
reducing neuronal excitability .
8. Which region of the brain is responsible for coordinating voluntary
movement and maintaining balance?
A) Amygdala
B) Basal ganglia
C) Thalamus
D) Hypothalamus
Answer: B) Basal ganglia
Rationale: The basal ganglia are involved in coordinating motor movements,
maintaining balance, and facilitating smooth muscle control .
9. Which neurotransmitter is commonly associated with reward, pleasure, and
addiction?
A) Serotonin
B) Dopamine
C) GABA
D) Glutamate
Answer: B) Dopamine
