Q1. Which three major categories describe cerebral white matter fibers?
- Dorsal, ventral, and lateral roots
- Gray, white, and reticular fibers
- Association, commissural, and projection fibers
- Sensory, motor, and autonomic nerves
Q2. What do association fibers connect?
- The spinal cord directly to skeletal muscle
- Only the two cerebral hemispheres
- Cortical areas within the same hemisphere
- The cerebellum to peripheral nerves
Q3. What do commissural fibers connect?
- The two cerebral hemispheres
- Only adjacent gyri in one hemisphere
- The cerebellum and vestibular apparatus
- The spinal cord and medulla
Q4. What do projection fibers connect?
- Only neighboring cortical gyri
- Cerebral cortex with deeper neural structures
- Only cerebellar folia
- Only the right and left hemispheres
Q5. What is the corona radiata?
- A layer of the cerebral cortex
- A commissure between occipital lobes
- Fan-shaped projection fibers between cortex and internal capsule
- A meningeal venous sinus
Q6. What is the internal capsule?
- A dural fold
- A compact concentration of cerebral projection fibers
- A ventricular recess
- A cortical sulcus
Q7. Which ventricular cavities lie within the cerebral hemispheres?
- Cerebral aqueduct
- Lateral ventricles
- Central canal
- Fourth ventricle only
Q8. Which deep gray matter structures are closely associated with the cerebrum and participate in motor and related circuits?
- Cerebellar nuclei only
- Cranial nerve nuclei
- Dorsal column nuclei
- Basal nuclei
Q9. Which arteries provide the principal arterial supply to the cerebral hemispheres?
- Basilar, facial, and lingual arteries
- Anterior spinal, PICA, and AICA only
- Middle meningeal, occipital, and maxillary arteries
- Anterior, middle, and posterior cerebral arteries
Q10. What is meant by cortical somatotopy?
- Random distribution of cranial nerves in cortex
- Separation of gray matter from white matter
- Arrangement of cerebral arteries around the brainstem
- Orderly cortical representation of different body regions
