What are the 3 major structures of the nervous system? - ✔✔CNS, PNS, Crossed
Representation
What is involved in the CNS? - ✔✔Brain + spinal chord, and upper motor neurons
What is involved in the PNS? - ✔✔All nervous tissue outside the CNS, spinal + cranial nerves,
and lower motor neurons
What is "crossed representation"? - ✔✔Left side of the brain communicates with the right side
of the body
What is the nervous system responsible for? (4) - ✔✔Various senses; speech, memory,
emotions, thought; control body movements; regulates internal organs (maintaing
homeostasis)
What are the 3 basic functions of the nervous system? - ✔✔1. Sensory
2. Integrative
3. Motor
What is the function of the Sensory, Integrative & Motor areas of the nervous system? - ✔✔1.
Sensory = detect stimuli
2. Integrative = process information, then decides what to do
3. Motor = activation of muscles/glands
What are the 4 main areas of the brain? - ✔✔Cerebrum, thalamus + hypothalamus, cerebellum,
and brain stem
,What areas are included in the cerebrum? (3) - ✔✔Hemispheres, cerebral cortex, basal ganglia
What are the functions of the cerebrum? - ✔✔-Ability to speak
-Math calculations
-Remember the past, plan the future
-Gives us our intelligence
Does the cerebral cortex contain grey or white matter? - ✔✔Outer grey layer (grows faster than
white matter, increases surface area, looks bumpy)
What are the names of the cerebral cortex lobes? (4) - ✔✔1)Frontal
2)Parietal
3)Occipital
4)Temporal
What is the the main function of the frontal lobe? What important area is located within it? -
✔✔-Voluntary movement
-Broca's area
What is the function of the parietal lobe? - ✔✔Primary sensation center
What is the function of the occipital lobe? - ✔✔Primary visual receptor center
What is the function of the temporal lobe? What important area is located within it? - ✔✔-
Interprets information (makes sense of)
-Wernicke's area
, What type of aphasia is caused by damage to Wernicke's area? Explain. - ✔✔-Receptive aphasia
-Can hear you but can't understand you ("word salad")
What is the function of the basal ganglia and where is it located? - ✔✔-Controls automatic
movements
-Within the cerebrum
What is the main function of the thalamus? - ✔✔Major relay station
What is the main function of the hypothalamus? - ✔✔Regulates hormones, temperature
appetite, pleasure, pain, sleep/wake cyle ("hub between mind and body")
What is the cerebellum responsible for? (2) - ✔✔-Skilled movement
-Posture/balance
What 3 structures are involved in the brain stem? - ✔✔1. Midbrain
2. Pons
3. Medulla Oblongata
What is the function of each: midbrain, pons, medulla oblongata? - ✔✔-Midbrain = connects
spinal card to thalamus
-Pons = ascending/descending fibre tracts
- Medulla Oblongata = vital + other centers; continuation fibers
What structure is considered the "main pathway"? - ✔✔Spinal cord
What is the difference between grey matter & white matter? - ✔✔Grey = size of integration,
White = dozens of sensory/motor tracts
