bumps on head = personality traits (WRONG)
brain is divided into regions (CORRECT)
larger the region the more important (SORT OF CORRECT)
studpid dum dum
Frontal Lobe
moving and coordination
-short term memory
-planning
- motor control
Temporal lobe
hearing
- controls senses
- language
- memory
Occipital lobe
seeing
visual processing
cerebellum
motor function
Meninges (3)
dura matter - tough and flexi
Arachnoid - cerebrospinal
Pia matter - saran wrap
Ventricles
The blue part is the ventricles that secrets cerebral spinal fluid
empty space that flows down into spinal cord
Choroid plexus
produces and absorbes cerbrospinal fluid
what happens if there is an over production of cerebrospinal fluid
called HYDROcephalus
put pressure on the brain and can cause damage
Blood Brain Barrier BBB
regulation of blood that carries oxygen
Ischemic Stroke
BLOCKS BLOOD (clot)
pertaining to the stoppage of blood
Hemorragic stroke
BRAIN BLEED
pertaining to the rapid flow of blood
Brainstem
responsible for most of our uncoscious behaviors
Three regions
-diencephalon
-midbrain
-hindbrain
Brainstem: Pons (hindbrain)
Pons = “bridge”
processing in sleep
Brainstem: reticular formation (hindbrain)
inside the Pons
send signals to make you wake up
Brainstem: Cerebellum (hindbrain)
motor function
balance
Brainstem: Medulla (hindbrain)
heartbeat control
Brainstem: Tectum (midbrain)
Superior Colliculus - what?/visual
Inferior Colliculus - where?/auditory
Brainstem: Tegumentum (midbrain)
arousal
self-conciousness
Brainstem: Substantia Nigra (midbrain)
movement (parkinsons disease)
