3D. Cerebrum Flashcards
____________ ventricles for the production of cerebral spinal fluid
Lateral
Transverse cerebral fissure
The fissure that runs along the midline. Represented by a fold of dura, identified as the Falx Cerebri
longitudinal cerebral fissure
Helps to serve as a dividing landmark between various phylogenetic stages of development of the cerebrum
- separates Rhinencephalon from rest of cerebrum
Lateral Rhinal
Serves as a landmark for the motor cortex in the cerebrum
Cruciate
means smooth brain
Lissencephaly
Functional Associations of Cerebral Lobes:
Motor cortex and thought
frontal lobe
Functional Associations of Cerebral Lobes:
Sensory cortex (conscious awareness of various pathways and modalities)
parietal lobe
Functional Associations of Cerebral Lobes:
The portion of the cortex that processes auditory information and it is also the site where we have memory processing and tie-ins with the emotional system
temporal lobe
Functional Associations of Cerebral Lobes:
Processes visual information
occipital lobe
Rhinencephalon: paleocortex
is the dividing landmark
lateral rhinal sulcus
Olfactory system from most rostrally to caudal :
olfactory bulb
olfactory tract
piriform lobe
Is the cortical area where the actual sense of smell is perceived
piriform lobe
White matter fiber systems:
- ascending and descending tracts
Projection fibers
White matter fiber systems:
- short or INTRAlobar (within lobe or short) between adjacent gyri
- long or InTERlobar between lobes; example: cingulum
Association fibers
White matter fiber systems:
- cross the midline in both directions between hemispheres
- corpus callosum (largest bundle of fibers that cross between left and right halves)
- rostral commissure (smaller band of fibers that passes from right to left)
Commissural fibers
Smaller band of fibers that pass from right to left. are associated with the olfactory system
rostral commisure
Internalized Gyrus of the temporal lobe of the cerebrum
- functions in memory processing
- historic site for Negri Bodies examination (in order to diagnose rabies)
Hippocampus
White matter bundles that pass between adjacent gyri belong to which system of white matter fibers?
Short Association
Which feature divides the cerebellum from the rest of the cerebrum?
Transverse cerebral fissure
Olfaction is associated with which lobe of the cerebrum?
Piriform
The rhinencephalon process information related to which sensory system?
Olfaction
Vision is processed through which cerebral lobe?
Occipital
White matter bundles that pass between lobes belong to which system of white matter fibers?
Long association
Which feature divides the rhinencephalon from the rest of the cerebrum?
Lateral rhinal sulcus
