BIOD 152 Lab 1 Practice Exam (100 Questions)
Instructions: This practice exam covers brain anatomy, cranial nerves, neuron
physiology, reflexes, and related concepts typically assessed in Lab 1. Bold
italic text highlights key terms. Each question includes the correct answer and
rationale.
SECTION 1: Brain Anatomy — Surface Features
1. The deep groove separating the left and right cerebral hemispheres is the:
• A) Central sulcus
• B) Longitudinal fissure
• C) Lateral sulcus
• D) Transverse fissure
Answer: B) Longitudinal fissure
Rationale: The longitudinal fissure is the deep groove that divides the brain into
left and right hemispheres.
2. The central sulcus separates which two lobes of the brain?
• A) Temporal and occipital
• B) Frontal and parietal
, • C) Parietal and occipital
• D) Frontal and temporal
Answer: B) Frontal and parietal
Rationale: The central sulcus is a prominent groove on the lateral surface of the
cerebrum that separates the frontal lobe (anterior) from the parietal
lobe (posterior).
3. The folds or ridges on the surface of the cerebrum are called:
• A) Sulci
• B) Fissures
• C) Gyri
• D) Folia
Answer: C) Gyri
Rationale: Gyri are the raised ridges of the cerebral cortex. Sulci are the shallow
grooves between them, and fissures are deeper grooves. Folia are the folds found
on the cerebellum.
4. The shallow grooves between the ridges of the cerebral cortex are called:
• A) Gyri
• B) Sulci
• C) Fissures
• D) Folia
Answer: B) Sulci
Rationale: Sulci are the shallow grooves that separate the gyri (ridges) of the
cerebral cortex.
,5. The folds on the surface of the cerebellum are called:
• A) Gyri
• B) Sulci
• C) Folia
• D) Villi
Answer: C) Folia
Rationale: Folia are the slender, parallel folds that characterize the cerebellar
surface, giving it a laminated appearance.
6. The white matter pattern inside the cerebellum that resembles a tree is
called:
• A) Arbor vitae
• B) Corpus callosum
• C) Corona radiata
• D) Internal capsule
Answer: A) Arbor vitae
Rationale: Arbor vitae ("tree of life") is the branching white matter pattern visible
in a sagittal section of the cerebellum.
7. The frontal lobe is primarily responsible for:
• A) Visual processing
• B) Auditory processing
• C) Motor planning and executive functions
• D) Sensory integration
, Answer: C) Motor planning and executive functions
Rationale: The frontal lobe contains the primary motor cortex and is responsible
for motor planning, personality, decision-making, and executive functions.
8. Injury to the parietal lobe would most likely cause impaired:
• A) Vision
• B) Hearing
• C) Interpreting of general senses
• D) Motor coordination
Answer: C) Interpreting of general senses
Rationale: The parietal lobe contains the primary somatosensory cortex, which
interprets general senses such as touch, temperature, and pain.
9. The temporal lobe is best described as the region responsible for:
• A) Motor coordination
• B) Hearing and smell
• C) Vision
• D) Executive function
Answer: B) Hearing and smell
Rationale: The temporal lobe contains the primary auditory cortex and olfactory
association areas, making it responsible for hearing and smell.
10. The occipital lobe is primarily responsible for:
• A) Vision
• B) Hearing
