Lab 3 - Forebrain / Midbrain Flashcards
two parts of forebrain
telencephalon, diencephalon
cortex, basal ganglia, limbic system and for higher cognitive function/emotion/motor control
telencephalon
part of forebrain that includes thalamus/hypothalamus, relays information to different brai nregions
diencephalon
two parts of midbrain
tectum, tegmentum
part of midbrain for visual and auditory processing
tectum
part of midbrain for autonomic functions, reflexes, attention
tegmentum
function of this cortex is for cognition/consciousness, motor function, and sensory processing
cerebral
cerebral cortex is blank matter
gray
cerebral cortex is made up of mostly blank because its gray matter
cell bodies
lobe of cerebral cortex for sensory/visual processing
occipital
lobe of cerebral lobe for sensory/auditory processing
temporal
lobe of cerebral cortex for sensory/cognitive/integration of sensory info
parietal
cerebral cortex lobe for cognition/high level functions
frontal
divides left and right cerebral hemispheres
longitudinal fissure
usually where language functions are localized but not always and does vocabulary/grammar/maybe long term memories
left hemisphere
cortex means blank
bark
cerebral has blank layers
six
damage to occipital lobe causes blank blindness
cortical
thick band of white fibers that internally connects the two hemispheres
corpus callosum
separates the temporal lobe from the frontal and parietal lobes
lateral sulcus
separates the frontal and parietal lobes
central sulcus
in the frontal lobe and is the primary motor area (M1)
precentral gyrus
in the parietal lobe and is the primary somatosensory area of face and UE
postcentral gyrus
the blank is the primary somatosensory area for LE
posterior paracentral gyrus
the precentral and postcentral gyri are organized blank which means the body surface is laid out on the surface of the cerebral cortex
somatotypically
the blank cortex is in the temporal lobe
primary auditory cortex
uppermost gyrus of temporal lobe… damaging this results in impaired speech COMPREHENSION… aka blank
wernicke’s area, wernicke’s aphasia
olfactory nerve cannot be seen blank
grossly
primitive part of telencephalon
hippocampus
part of limbic lobe in the corpus callosum
cingulate gyrus
an important integrating center for autonomic functions and endocrine system and emotion
hypothalamus
gland hanging from hypothalamus via the blank
pituitary, infundibulum
part of brain for initiating motor output, posture, eye movement, balance,
basal ganglia
part of brain for emotion, forming long term memories, stress response, arousal
limbic system
damaging the hippocampus causes loss of the ability to blank
form new long term memories
these connect the brain and relay signals between brain regions
commissures
new blank can be grown in the blank
hippocampus
three commissures
anterior, posterior, corpus callosum
anterior pituitary is blank tissue
endocrine
infundibulum is made of blank tissue
neural (axons)
anterior pituitary is not connected to blank
brain
there is a blank vein in the blank pituitary
portal, anterior
major central hub of the brain (relay station)
thalamus
thalamus relays information from blank to blank
cortex, brainstem
sensation, perception, movement, awareness, are all important functions of the blank
thalamus
above the thalamus and relays information between limbic system and other brain regions like circadian rhythm, olfaction, and motor response
epithalamus
midbrain part that has the superior/inferior colliculi
tectum
colliculus for visual processing
superior
colliculus for auditory processing
inferior
