Chapters
1. Which division of the nervous system is responsible for voluntary muscle
movement?
A. Autonomic
B. Somatic
C. Sympathetic
D. Parasympathetic
The somatic nervous system controls skeletal muscles and is responsible
for voluntary movements.
2. The "mind-body problem" is primarily concerned with:
A. How the heart controls emotions
B. The relationship between the brain and consciousness
C. How mental states relate to physical brain states
D. The function of glial cells
, This philosophical issue explores how subjective experiences arise from
physical brain processes.
3. Which brain imaging technique measures blood oxygenation levels?
A. CT
B. PET
C. fMRI
D. EEG
fMRI (functional Magnetic Resonance Imaging) detects changes in blood
oxygen levels, indicating brain activity.
4. The blood-brain barrier is primarily composed of:
A. Neurons
B. Axons
C. Cerebrospinal fluid
D. Tight junctions between endothelial cells
These tight junctions prevent harmful substances in the blood from
entering the brain tissue.
5. The resting membrane potential of a neuron is typically:
A. +70 mV
B. 0 mV
C. -70 mV
D. -30 mV
A resting neuron maintains a -70 mV potential due to the distribution of
ions across its membrane.
,6. Which neurotransmitter is most associated with muscle contraction?
A. Dopamine
B. Acetylcholine
C. Serotonin
D. GABA
Acetylcholine is released at neuromuscular junctions, enabling muscle
movement.
7. An action potential is triggered when the membrane potential reaches:
A. -90 mV
B. -70 mV
C. -55 mV
D. 0 mV
The threshold for triggering an action potential is typically around -55 mV.
8. The limbic system is most associated with:
A. Vision
B. Emotion and memory
C. Language
D. Voluntary movement
Structures in the limbic system, like the amygdala and hippocampus,
regulate emotion and memory.
9. The "split-brain" studies primarily investigated the role of the:
A. Cerebellum
B. Corpus callosum
C. Hypothalamus
, D. Occipital lobe
The corpus callosum connects the two hemispheres; its severance helped
researchers study lateralization.
10.Which of the following is a major inhibitory neurotransmitter in the CNS?
A. Glutamate
B. Dopamine
C. GABA
D. Serotonin
GABA (gamma-aminobutyric acid) reduces neuronal excitability in the
brain.
11.Which brain structure regulates the circadian rhythm?
A. Hippocampus
B. Amygdala
C. Suprachiasmatic nucleus
D. Pituitary gland
The SCN in the hypothalamus synchronizes the sleep-wake cycle with the
external light-dark cycle.
12.What is neuroplasticity?
A. Formation of new neurons
B. Destruction of neurons
C. Brain’s ability to change structurally and functionally
D. Genetic coding of behavior
