what are the 10 functions of the hypothalamus
- Regulates sleep-wake cycles. Suprachiasmatic nucleus (biological clock)
- Thirst centers.
- Controls electrolytes and ions
- Regulates body temperature
- Autonomic control center for many visceral functions
- Produces hormones
- Controls the Endocrine system
- Blood pressure, rate and force of heartbeat,
- hunger center
- respiration
parkinsons is the ___ of the nuclei. it does/not have lots of dopamine
huntington/schizophrenia is the ___ of the nuclei it does/not have lots of dopamine
parkinsons = overactive nuclei, lots of dopamine
huntington = deterioration nuclei, low dopamine

what are the 3 organs of the brain stem?
midbrain, pons, medulla oblongata
The primary auditory cortex is located in
temporal lobe
What are the diencephalon structures? (11)
Thalamus
- Hypothalamus
- posterior pituitary gland
- mamillary bodies
- pineal gland

all sensory info is first relayed here
thalamus
function of the reticular formation
alertness
can trace picture but cannot recognize it. damage in the
visual association area
lymbic system function
emotion regulation
meningitis - usually in which layers?
inflammation of the meninges, usually in the pia & arachnoid mater
what is the function of the gyri and sulci?
increase SA
is cerebral cortex white or grey mater
grey
pituitary gland is related to the ___ thru the ___
hypothalamus, infundibulum
dorsal horn
lateral horn
ventral horn
contains what?
dorsal = interneurons lateral = visceral motor neurons ventral = somatic motor neuronss
spinothalmic tract is ascending or descending tract
ascending

flaccid paralysis
flaccid paralysis is damage in the upper/lower motor neurons
lower motor neuron
there are no ___ in CSF
RBC
this nerve bypasses the thalamus
olfactory
gustatory is which location of brain
insula
intelligence, abstract thinking in the ___ lobe
frontal
function of the occipital lobe
vision
the pyramidal tract (corticospinal) originates in the ___
cortex
helps maintain brains stable enviornment
blood brain barrier
hydrocephalus in adutls are critical because
bones dont expand so increases in cranial pressure damages the brain
language/math is dominant in which hemisphere
left
ascending pathways end in the
somatosensory cortex
