Cerebral cortex Flashcards
The two hemispheres are separated by the…
longitudinal fissure
The sulcus that separates the frontal lobe from the parietal lobe is the…
central sulcus
The sulcus that in found in the occipital lobe on its medial surface is the….
calcerine sulcus
From which view is the parieto-occipital fissure is best seen
medial
The precentral gyrus functions as this center of the brain
primary motor cortex- the beginning of the corticospinal (voluntary) pathway
What cells make up the beginning of the corticospinal pathway
pyramidal cells
The pathway for pain, temperature and crude touch, tickle, itch
spinothalamic
The pathway for discriminative touch, pressure, vibration and proprioception
dorsal columns
This means that each region of the body has a specific location for its cells bodies for motor or termination site for sensory pathways
somatotopic arrangement
In which lobe is Broca’s speech area located
frontal (left)
This region feeds information to the precentral gyrus prior to the activation of the corticospinal pathway
supplementary motor cortex
The primary function of the parietal lobe
perceiving and interpreting sensory information (like taste!)
the primary auditory cortex and Wernicke’s area is found in this lobe
temporal
What is the arcuate fasciculus?
the white matter pathway connecting Wernicke’s (temporal) and Boca’s (frontal) areas
where does the visual pathway terminate
on the area surrounding the calcarine fissure
