cerebral hemispheres Flashcards
the brain developed from the ______ composed of _______
neural tube, neuroepithelium
embryonic brain regions
forebrain midbrain hindbrain
forebrain derivatives
telencephalon diencephalon
midbrain derivatives
mesencephalon
hindbrain
metencephalon myelencephalon
what does the telencephalon form in the child/adult brain structure
cerebrum (includes cerebral cortex, white matter, basal nuclei)
functions of the frontal lobe
executive functions, thinking, planning, organizing and problem solving, emotions and beavioral control, personality
functions of the parietal lobe
perception, making sense of the world, arithmetic, spelling
function of occipital love
vision
function of the medulla oblangata
breathing, heart rate, respiration
–Last region in the cortex before motor information descends to lower regions of the nervous system
primary motor cortex
_______ is the first region in the cortex to receive sensory information
•Primary Sensory Cortex
Then sent to association areas for detailed processing
primary sensory cortex
cerebral lobe and cortical region where somatic motor happens
precentral gyrus in the frontal lobe (M1)
cerebral lobe and cortical region where somatosensation occurs
postcentral gyrus of parietal lobe (S1)
cerebral lobe and cortical region where speech/language occur
broca’s and wernicke’s area in the LEFT side of the frontal and temporal lobes
cerebral lobe and cortical region area where vision occurs
banks of calcarine sulcus in the occipital lobe
cerebral lobe and cortical region where audition happens
transvere temporal gyri in the temporal lobe
cerebral lobe and cortical region where olfaction happens
uncus and anterior temporal lobe in the temporal region
function of broca’s area and lobe its in
- language production
- speaking writing singing
- frontal lobe
broca’s aphasia
slowed, labored speech
- agrammatism, anomia
function of wernicke’s area and location
language comprehension
- speechm, written language, signed language
- temporal lobe
the dominant hemishphere for language processing
left
The _______ (Latin: curved bundle) is a bundle of axons that connects Broca’s area and Wernicke’s area in the brain
arcuate fasciculus
in the axonal pathway of the arcuate fasciculus, cell bodies are in the ______ and axon synapse are in the _____
Wernicke’s area
Broca’s area
nuclei of the basal ganglia
–Caudate nucleus
–Putamen
–Globus pallidus
–Substantia nigra
–Subthalamic nucleus
Tonotopic organization
Both hemispheres process auditory information from each ear!
3 parts of the telencephalon
- cerebral cortex
- white matter fiber systems
- basal ganglia
Thin, outer covering demarcated by gyri, sulci & fissures
–Cerebral cortex
What blood vessel supplies the leg region of the precentral gyrus on the right?
–Right ACA
What blood vessel supplies Wernicke’s area on the left?
–Left MCA
What blood vessel supplies the primary visual cortex on the right?
–Right PCA
