name the 4 regions of the brain
|
cerebrum
cerebellum diencephalon Brain stem |
|
all regions of the brain have grey matter on the outside except for the
|
brainstem
|
|
name the two halves of the cerebrum
|
left and right hemisphere
|
|
name the 5 lobes that each cerebral hemisphere is divided into
|
Frontal
Parietal temporal Occipital insula |
|
Controls conscious thought; damage can result in mood changes
|
Frontal lobe
|
|
plays important roles in integrating sensory information from various senses, and in the manipulation of objects; portions of the parietal lobe are involved with visuospatial processing
|
Parietal lobe
|
|
controls sense of sight; lesions can produce hallucinations
|
Occipital lobe
|
|
Controls senses of smell and sound, as well as processing of complex stimuli like faces and scenes.
|
Temporal lobe
|
|
a portion of cortex in between and covered by the temporal and parietal lobes. Many sources consider it a separate lobe, and some group it with limbic structures deep in the brain into a limbic lobe
|
Insula
|
|
links sensory input with motion; this is especially involved with maintaining balance.
|
Cerebellum
|
|
allows the two lobes to communicate information to each other
|
Corpus callosum
|
|
outward folds in the brain
|
gyri (gyrus)
|
|
shallow depressions between Gyri
|
sulcus
|
|
irregular shaped clusters of neuron cell bodies within the white matter of the brain
|
cerebral nuclei
|
|
structures that protect the brain
|
bony cranium
meninges Cerebrospinalfluid (CSF) Blood brain barrier |
|
3 layers of meninges from superficial to deep
|
duramater
piamater arachnoid layer |
|
tough membrane composed of two fibrous layers. is the strongest of the meninges
|
duramater
|
|
name the 2 layer that make up duramater
|
periosteal layer (attached to cranial bones)
meningeal layer (fused to the periosteal layer) |
|
areas where the meningeal layer separates from the periosteal layer to form large, blood filled spaces called _____
|
dural venous sinuses
|
|
composed of a web of collagen fand elastic fibers that forms a web like structure
|
arachnoid
|
|
space between the duramater arachnoid space
|
subdural space
|
|
space found deep to the arachnoid
|
arachnoid space
|
|
inner most of the cranial meninges. is a thin layer of delicate connective tissue that tightly adheres to the brain and follow every contour of the brain surface
|
pia mater
|
|
mambranous partition of duramater that extends as flat partitions deep into the cranial cavity.
|
cranial dural septa
|
|
name the 4 areas of cranial dural septa

|
glial cell that secretes CSF
|
ependymal cells.
