cerebral hemispheres Flashcards
what are the 4 lobes?
- Frontal
- Parietal
- Occipital
- Temporal
what seperates the L + R hemispheres?
the longitudinal fissure
what sperates the anterior + posterior parts of the hemispheres? (and lobes )
the central sulcus
seperates the frontal + parietal lobes
what seperates the temporal lobe from the parietal and frontal lobes
the lateral fissure
what sperates the parietal and occipital lobe
the lateral fissure
from a superior view: what are the 3 lobes anterior->posterior
anterior: frontal
parietal
posterior: occipital
list the areas of each hemisphere (12)
- Primary Somatic Sensory Cortex
- Somatic Sensory Associated Area
- Visual Cortex
- Visual Associated Area
- Wenicke’s Area
- Taste Area
- Auditory Associated area
- Primary Auditory Cortex
- Brocca’s Area (motor speech)
- Prefrontal Area
- Premotor Area
- Primary Motor Cortex
which areas are involved with speech?
werknicke’s area (sensory speech)
brocca’s area (motor speech)
Primary somatic sensory cortex
receives sensory APs from entire body
is divided up into different area which receive sensory info from different parts of the body
Somatic sensory associated cortex
receives + processes sensory APs
Visual Cortex
parasymphatetic
Visual Associated area
receives sensory visual info and translates APs to images
Werknicke’s area
sensory speech
taste area
sensory taste
Auditory associated area
translates sensory sound APs into sound menones and matches these to stored existing menones allowing for sound recognition + comparison
