1
Q
6 major areas of the CNS
A
- cortex
- basal ganglia
- limbic system
- cerebellum
- brain strem
- spia; cord
2
Q
Spinal cord
A
- connects to PNS
- protected by vertebrae
- spinal reflexes
3
Q
what is the spinal cord protected by
A
vertebrae
4
Q
the brain
A
- complex structure that demands huge amount of our bodily resources
- 1.4 kg of protein, fat, and fluid
5
Q
3 major regions of the brain
A
- forebrain
- midbrain
- hindbrain
6
Q
what is the forebrain compromised of
A
- cerebral cortex
- basal ganglia
- limbic system
7
Q
Cerebral cortex
A
- folds of cortex
- outer layer of the brain (divided into two hemispheres)
8
Q
what are the two hempispheres connected by
A
- the corpus callosum
9
Q
Left Hemipshere is responsible for
A
- fine tuned language skills
- actions
10
Q
Right hemispheres is responsible fore
A
- coarse language skills
- visuospaital skills
11
Q
lobes of the cortex
A
- frontal
- parietal
- temporal
- occipital
12
Q
Frontal lobe functions
A
- motor
- organization of other brain functions
- language
- memory
13
Q
Parietal lobe functions
A
- touch
- temperature
- pain
- perception
14
Q
Temporal lobe functions
A
- auditory processing
15
Q
Occipital lobe functions
A
- visual processing
16
Q
Basal Ganglia function
A
- critical for motor function
17
Q
disfunction or damage to the basal ganglia can result in
A
involuntary movements
18
Q
Limbic system function
A
- emotion
- memory
- learning
19
Q
the limbic system is made up of
A
- amygdala
- hippocampus
- thalamus
- hypothalamus
20
Q
function of the midbrain
A
- controls eye movements and coordination
21
Q
what is the most important area of the midbrain
A
reticular activating system (RAS)
22
Q
RAS function
A
- essential for conscious awareness and control of existence.
- also regulates sleep, wakefulness, and attention
23
Q
the hindbrain is comprised of
A
- medulla
- pons
- cerebellum
24
Q
divisions of the peripheral nervous system
A
- somatic nervous system
- autonomic nervous system
25
what are the two divisions of the autonomic nervous system
- sympathetic
- parasympathetic
26
both divisions of the autonomic nervous system work together to achieve
homeostasis
27
sympathetic nervous system
- activation function
- arousal
- fight or flight system
28
parasympathetic nervous system
- inhibits function
- decreases arousal
- feed and breed system
- rest and digest system
29
contraction of the pupil is done by what system
- parasympathitic
30
constricted bronchi is done by which system
parasympathetic
31
dialated pupils is done by what system
sympathetic
32
accelerated, strenghten heart beat is done by what system
sympathetic
33
relaxed bronchi is done by which system
sympathetic
34
slow heart beat is done by which system
parasympathetic
35
stimulated activity is the digestive organs is done by which system
parasympathetic
36
contraction of blood vessles is done by which system
sympathetic
37
inhibited activity is the digestive organs is done by which system
sympathetic
38
dialated blood vessels is done by which system
parasympathetic
39
somatic nervous system function
- voluntary muscle activation
