PRN1725 CCC4 Exam 1
1. Neuron does what?
reacts to stimuli, conducts impulses, and influences other neuron
2. Neurological System consists of...
CNS and PNS
3. CNS is made up of
brain and spinal cord
4. Brains 4 major regions
*cerebrum
-center of intellect and consciousness
*diencephalon
-thalamus: relay center between spinal cord and cerebrum
-hypothalamus: controls body temp., appetite, and water balance
*cerebellum
-coordination of movement, posture, and muscle tones that are for balance
*Brainstem
-midbrain: mediates visual and auditory reflexes
-pons: links connecting various parts of the brain and helps regulate resp.
-medulla oblongata: helps regulate HR, resp. and BP
, 5. Spinal cord extends from
medulla to first lumbar vertebra
6. Pyramidal tracts
conduction pathways that begin in cerebral cortex and end in spinal cord
7. Pyramidal tracts control
skeletal muscle movements
8. Extrapyramidal tracts control
muscle movements associated with posture and balance
9. PNS made up of
cranial and spinal nerves
10. Sensory impulses travel
ascending conduction pathway tracts
11. Motor impulses travel
descending tracts
12. Remember which nerves are sensory and which are motor.
