3 divisions of brain |
cerebrum brainstem cerebellum |
|
|
Cerebral cortex |
outer section of brains hemispheres, controls intellectual activity |
|
|
Cerebral medulla |
lower part of cerebrum where nerve signals directed |
|
|
Right hemisphere controls? |
creativity, imagination, visual processing |
|
|
Left hemisphere controls? |
logic and reason used to form judgements and solve problems. Dominates language, speech functions |
|
|
Lobes of Cerebral cortex |
frontal, parietal, occipital, temporal |
|
|
Frontal lobe controls? |
Voluntary muscle movement Abstract thought problem solving planning, emotions |
|
|
Parietal controls? |
sensory messages of touch, pressure, pain, temp, vibration, orientation |
|
|
Temporal controls? |
visual memory, interpreting others emotions, hearing, speech, depth perception, sense of time |
|
|
Occipital controls? |
visual processing- eyesight, reading, colors, shapes |
|
|
contralateral |
control over opposite side of body |
|
|
Neuron |
cell in nervous sytem resp. for transmission, processing of info; nerve cell |
|
|
White matter |
In cerebral medulla, myelin insulated, resp for info transmission |
|
|
Gray matter |
basal ganglia, controls fine, gross motor movement If deteriorated, Parkinsons and Huntingtons can result |
|
|
Hippocampus |
Part of limbic system. records initial experiences |
|
|
Amygdala |
part of limbic system, deals w/emotional response |
|
|
Limbic system |
group of neurons, brain components that control behavior, emotion |
|
|
Components of brain stem |
medulla oblongata pons diencephalon |
|
|
medulla oblongata |
part of brain stem. Controls necessary function for life: cardiac, vasomotor, respiratory |
|
|
pons |
relays messages btwn cerebrum, cerebellum controls breathing rate Nerves originating from pons involved w/eye, facial movements, taste, hearing, balance |
|
|
Diencephalon |
includes thalamus, hypothalamus |
|
|
cerebrum, brainstem, cerebellum counterparts |
forebrain, midbrain, hindbrain |
|
|
Thalamus |
sends sensory messages about pain, temp, touch to parietal lobe of cerebral cortex Sensory messages also originate in eyes, ears, nose |
|
|
Hypothalamus |
In charge of many involuntary functions that enable homeostasis |
|
|
Medulla oblongata |
Uses white matter to control: heart breathing BP Key reflexes: swallow, cough, vomit, gag |
|
|
Cerebellum |
posture balance coordination Ipsilateral |
|
|
Reticular formation |
connects brainstem, cerebrum via excitatory or inhibitory nerve fibers Ex: caffeine stimulates excitatory fibers |
|
|
4 common neurotransmitters in brain |
ACH NE Dopamine Seratonin |
|
|
brainstem |
Primitive part of brain where involuntary functions take place |
