HPD Neuro Quiz
1. What are the two parts of the nervous system?: Central Nervous System (CNS)
- Brain and Spinal Cord
Peripheral Nervous System (PNS)
- Cranial, Spinal, and Peripheral nerves
2. What are the 4 regions of the brain?: 1. Frontal lobe
2. Occipital lobe
3. Parietal lobe
4. Temporal lobe
3. What are the subdivisions of the brain?: 1. Cerebrum: outer layer of gray matter (cerebral cortex)
+ central white matter
- divided into 2 cerebral hemispheres
- each hemisphere divided into 4 lobes: frontal, parietal, temporal, occipital
- Cortex: outer layer (gray matter)
- subcortical structures (fornix, cingulate cortex, basal ganglia, and basal forebrain
2. Diencephalon: thalamus, epithalamus, subthalamus, and hypothalamus (sensory and homeostasis)
,3. Cerebellum: coordination, balance and complex motor function
4. Brainstem: midbrain, pons, and medulla (automatic function, movement coordination, sensory processing)
4. What are the segments of the spinal cord?: Cervical: C1-C7
Thoracic: T1-T12
Lumbar: L1-L5
Sacral: S1-S5
Coccygeal: C1
5. Describe the somatic and autonomic systems of the PNS.: Somatic
- muscle movement, response to touch and pain sensation
Autonomic
- controls automatic functions (digestion, HR, BP)
, Sympathetic: mobilizes organs under stress and arousal
Parasympathetic: conserves energy/resources during rest/relaxation
6. How many spinal nerves attach to the spinal cord at each level?: Cervical: 8
Thoracic: 12
Lumbar: 5
Sacral: 5
Coccygeal: 1
7. Where do the cranial nerves emerge from?: CNs I and II are white matter tracts and emerge
from the brain
CNs III-XII arise from the brain stem
8. How are cranial nerves numbered?: - numbered sequentially in rostral (anterior) to caudal
(posterior) order as they arise from the brain and brainstem
9. Where do the cranial nerves pass through?: - the cranial vault through skull foramina and
canals
10. Where do motor neurons send commands to and for which functions?: Send
commands from the brain to the muscles
