Neuro - Everything Flashcards
primary motor cortex
Brodmans 4
- sends neural messages to the muscles via pyramidal pathways
- modulated by extrapyramidal pathway
premotor cortex
- Brodmans 6
- initation and planning of skilled motor movements
Broca’s Area
- Brodmans 44,45
- programs pattenred movements of vocal apparatus for phonemes and words
prefrontal cortex
Brodmans 9,10,46
-contributes to abstract thinking, problems solving, judgment (EFs)
frontal lobe areas
- primary motor cortex
- premotor cortex
- broca’s
- prefrontal cortex
parietal lobe
primary soamtosensory cortex (postcentral gyrus)
- angular gyrus
- supramarginal gyrus
primary somatosensory cortex/ postcentral gyrus
Broddmans 3,1,2
-sensations analyzed, elaborated, connected with multiple stimuli from other parts of the brain
angular gyrus
Broddmans 39
-translating written words to internal monologue (readig), writing, and language functions
supramarginal gyrus
Broddmans 40
-same as angular, translates written words to internal monologue, writing, calculaton, right/left distinctions, and language functions like metaphors and abstraction
temporal lobe
primary auditory cortex
wernicke’s area
primary auditory cortex
Broddmans 41,42
-processes sound information
wernicke’s area
Broddmans 22
-developing ana;ysis of auditory stimuli to point of comprehension
Occitpital lobe
- primary visual cortex, Broddmans 17
- processes visual information
Limbic system
- cingulate gyrus, hippocampus, amygdala
- so it supports functions including emotion, behavior, long-term memory, olfaction
brainstem
-regulation of cardiac and respiratory functioning, consciousness, relaying info through cranial and spinal nerves
