Topic 19: Nervous System - CNS - Forebrain - Cerebrum Layers - cortex Flashcards
What are the 3 layers of the cerebrum?
- cerebral cortex
- tracts (white matter)
- basal nuclei
What are the functional areas of the cerebral cortex?
- motor areas
- sensory areas
where are the motor areas of the cortex?
- all in frontal lobe
What is the function of the motor area of the cortex?
- control skeletal movement
What are the 3 regions of the motor area of the cortex?
- primary motor area (precentral gyrus)
- premotor area
- Broca’s area (motor speech)
What are the 4 sensory areas?
- general sensory area (pain, touch, temp, pressure)
- vision
- auditory and olfaction
- taste and visceral sensation
Where is the genral sensory area?
- postcentral gyrus in parietal lobe
Where is the vision sensory area?
occipital lobe
Where is the auditory and olfaction sensory area?
- temporal lobe
Where is the taste and visceral sensation area?
insula
ex. full bladder
What do the associated areas of the cerebral cortex recognize?
- recognize info from memories
- in parietal, occipital, temporal lobes
Where is memory stimulated in in the cortex?
temporal lobe
note this is non-associated (remember smth not triggered by sensory)
Where is conscious intellect (personality, learning, ideas, judgement, etc.) controlled by?
prefrontal cortex
