what are the openings in the fourth ventricle called?
aperatures
how does the cerebral spinal fluid form and travel through the brain?
forms and flows through lateral ventricles, third ventricle, fourth ventricle, and then out the little holes in the fourth ventricle to the subarachnoid space in the meninges and down the central canal of the spinal cord
what are the functions of the cerebrospinal fluid?
buoyancy
protection
chemical stability
What are the three parts of the brain stem?
midbrain
pons
medula oblongada
Which lobe of the brain is responsible for motor function?
frontal
in which lobe is the premotor cortex (motor association area) found?
frontal lobe
What is the premotor cortex responsible for?
planning of voluntary movements
where does the premotor cortex send impulses?
primary motor cortex
where do the upper motor neurons originate?
primary motor cortex
name pink highlighted gyrus
primary motor cortex
name pink highlighted part
premotor cortex
name pink highlighted part
central sulcus
what is the gyrus name for the primary motor cortex?
precentral gyrus
In sensory areas of the brain, does the information go to the primary or assocation area first?
primary
In the motor control areas of the brain, does the information go to the association area or the primary area first?
association
name the pink highlighted region.
what happens here?
primary visual cortex
receives signals from the eyes
name the pink highlighted region.
what happens here?
Visual association area
where we make sense of what we are seeing
name pink region
what signals does it receive?
what is its gyrus name?
primary somesthetic cortex
sensory - touch, pain , temp
post central gyrus
name sensory pink highlighted region
what does it do?
sensory association area
processes the sensory input - texture, shape, etc
what is the temporal lobe responsible for?
emotions
senses
memories
what areas of the cortex are involved in language?
Broca’s area
Wernicke’s area
name the pink highlighted region
what happens here?
Wernicke’s Area
recognize language
name the pink highlighted region
what happens here?
Broca’s Area
creates the motor program to say the word
primary motor cortex is when the word is spoken
what is the prefrontal cortex responsible for?
personality
what are the three cerebral white matter tracts?
projection
commissural
association
name the cerebral white matter tract
what does it do?
projection tracts
into and out of the brain to and from the spinal cord
name the cerebral white matter tract
what does it do?
commissural tract
go from left to right across hemispheres
name the cerebral white matter tract
what does it do?
association tracts
goes from gyrus to gyrus or lobe to lobe in the same hemisphere
what are the basal nuclei
what do they do?
masses of gray matter
smooths motor movements
what can damage to the basal nuclei cause?
issues like tremors in parkinsons
name the blue part of the brain stem
what is located here?
diencephalon
thalamas
name the red part of the brain stem
what stimuli does it process?
midbrain

name the green bulge in the brain stem
what stimuli does it regulate??
pons
respiration
name the green shaft at bottom of brain stem
what stimuli does it control?
medulla
consciousness and arousal
what section of the brain receives all sensory information
what order neuron is it?
thalamas
2nd order neuron
