central nervous system
diencephalon
CNS protection
brain stem
cerebellum
spinal cord
cerebrum
post central gyrus
Broca areas
Wernicke areas
three tracts
insula
pre central gyrus
Parietal lobe
Temporal lobe
Occipital lobe
Frontal lobe
vision
auditory and olfactory cortex
receives sensory information and process it.
attention planning decision making
understand speech name object
record words
control motor movement of speech
gustation cortex for taste general visceral sensation
memory emotions smell hearing
sense of touch , sounds and body parts. awareness of somatic division
stretch discomfort pain
primary somatosensory cortex
primary motor cortex
commissural
projection
association
connect parts in same hemisphere
connect parts indifferent hemisphere
sensory information goes up motor cortex goes down
thalamus- multi nucleated
hypothalamus
epithalamus
pineal gland
melatonin prepare us for sleep
control endocrine
regulate the secretion of pituitary hormones.
autonomic system
relay station
all sensory signals to cerebral cortex
except olfactory and orbit
amplify or tone down the signals
regulate temperature
emotional for behavior and sex
regulate food and water intake
visceral function
regulate sleep and wake
memory formation
medula oblongata
pons
midbrain
cerebral peduncles
pyramidal motor tracts from cerebrum to spinal cord
corpora quadrigemina
superior colliculi
inferior colliculi
visual reflex
auditory reflex
middle cerebral peduncle
reticular formation nuclei
connect cerebellum to cerebral cortex
autonomic behavior
structures
unconscious functions
vasomotor center- blood pressure
respiratory center- breathing rate
cardiac center - heart
decussation pyramid
cranial nerve nuclei
pyramids
sensory tracts
cortex of pre central gyrus- motor output through pyramidal tract
cross over from one side to another
all ascending sensory information
all parts of brain stem,
cranial nerve connect with brain
ascending afferent
cerebellar peduncles
cerebellum
coordinate body movement
maintains upright posture
superior
middle
inferior
connect mid brain to cerebellum
connects pons to cerebellum
connects medulla oblongata to cerebellum
cauda equina
filum terminale-within cauda equina
conus medullaris
posterior root
anterior root
end of true spina cord
anchors conus medullaris to coccyx
nerve roots extending below conus medularis
carry visceral and somatic unipolar sensory to the CNS
carry visceral and somatic multipolar motors to the PNS
dural mater - dense fibrous connective tissue
epidural space only in spinal cord
arachnoid mater (delicate than dura mater)
pia mater - gentle fibrous connective tissue
sub arachnoid space
consist of adipose tissue
periosteum layer - only on brain
meningeal layer
dural sinuses
vascular and capillary rich
contains cerebral spinal fluid
in between dural mater layers
filled with deoxygenated blood which goes to internal jugular vein.
