-
cerebral dominance
hemisphere dominant form language - left hemisphere 90% of ppl
-
This hemisphere is for visual-spatial skills, intuition, emotion, and artistic and muscial skills.
right hemisphere
-
This hemishphere is for control of language, math, and logic
left hemisphere
-
hemispheres communicate almost__________ via________and functional integration.
instantaneously , fiber tracts.
-
hemispheres are almost identical when?
when looking at them
-
these fibers horizontal, connect different parts of same hemisphere
association fibers
-
these fibers are horizontal, connect gray matter of two hemispheres
commissural fibers
-
these fibers are vertical , connect hemispheres with lower brain or spinal cord
projection fibers
-
what are the three parts of the diencephalon
thalamus, hypothalamus, epithalamus......retina of eye.
-
what is 80% of the diencephalon?
thalamus
-
this is the gateway to the cerebral cortex
thalamus
-
this sort edits and relays ascending imput which includes impulses from hypothalamus for regulation of emotion and visceral funtion
impulses form cerebellum and basal nuclei to help direct motor cortices
impulses form memory or sensory integration
mediates sensation, motor activietes cortical arousal, learning and memory
thalamus
-
This deals with temp. and controls endoctrine system
hypothalamus
-
controls autonomic nervous system - blood pressure, rate and force of heartbeat, digestive tract motilit, pupil size
has to do with perception of pleasure, rage, fear and biological rhythms and drives
hypothalamis
-
This regulates body temperature - sweating/shivering
hypothalamis
-
this regulates hunger and satiety in response to nutrient blood levels or hormones
hypothalamis
-
this regulates water balance and thirst
hypothalamis
-
regulates sleep-wake cycles and controls endocrine system
hypothalamis
-
suprachiasmatic nucleus
biological clock
-
controls secretions of anterior pituitary gland and produces posterior pititary hormones
hypothalamis
-
makes melatonine which helps regulated wake and sleep cycles
epithalamus
-
pineal gland body extends from the posterior border of this and secretes melatonin
epithalamus
-
this hormone helps regulate wake and sleep cycles and is produced by what
melatonin - pineal gland
-
what is the three regions of the brain stem
mid brain, pons medulla oblongata
-
this controls the automatic behaviors necessary for survival
brains stem
-
this has nuclei associated with 10 of the 12 pairs of crainal nerves
brain stem
-
in the midbrain the cerebral penduncles ventrally what?
contain pyramidal motor tracts
-
cerebral aqueduct what?
channel connecting third and fourth ventricals
-
Which ventrical seperates the pons and the cerebellum
fourth
-
the fibers of this connects the higher brain centers and spinal cord and relay impulses between motor cortex and cerebellum
pons
-
in this you have the origin of the cranial nerves V, VI, VII
pons
-
In this you have the orgins of the craial neves VIII, IX, X, XII
Medulla Oblongata
-
This controls the Cardiovascular center
Medulla Oblongata
-
These are part of what - Cardiac center_Vasomotor center
Cardiovascular center
-
This adjusts the force and rate of heart contraction
Cardiac center
-
This adjusts blood vessel diameter for blood pressure regulation
Vasomotor center
-
This controls the Respiratory centers
medulla Oblongata
-
This generate respiratory rhythm and controls rate and depth of breathing with pontin centers
respiratory centers
-
vomiting
hiccuping
swallowing
coughing
sneezing
medulla oblongata
-
deals with input from cortex, brain stem and sensory receptors and allows, smooth, coordinated movements
cerebellum
-
treelike patteren of cerebellar white matter
arbor vitae
-
all fibers in cerebellum are ipsillateral
cerebellar peduncles
-
Role in thinking, language, and emotion. May compare actual with expected output and adjust accordingly
cognitve function of cerebellum
