Brain Neuroanatomy Flashcards
What does the brain consist of?
Cerebrum (R and L)
Cerebellum
Brain stem
What is the brain composed of?
Gray matter on outer surface, white matter tracts inside
What are the supportive structures of the brain?
Skull/cranium
Meninges
What supportive structure has 3 layers of membranes all continuous with membranes that cover and protect the spinal cord?
Meninges
What are the three types of meninges membranes?
Dura mater
Arachnoid
Pia mater
What is the outermost meninges layer known as “tough mother”?
Dura mater
What meninges is a thick, fibrous membrane that adheres to the cranium?
Dura mater
Where is the epidural space located?
area between the dura mater and the skull
What is the middle meninges layer?
Arachnoid
Where is the subdural space located?
The area between the dura mater and arachnoid layer
What meninges is the innermost layer, adheres to the brain itself, and contains cerebral circulation?
Pia mater
Where is the subarachnoid space located?
Area between the arachnoid and pia mater layers
What bathers the brain and circulates within the pia mater?
Cerebrospinal fluid (CSF)
What is the highest center of the CNS and largest part of the brain?
Cerebral cortex
What is a large information storage area?
Cerebral cortex
What is termed gray matter?
Cerebral cortex
What are the two halves of the cerebral cortex called?
Hemispheres
What are the grooves in the cortex called?
Fissures or sulci
What are the lobes of the cerebral cortex?
Frontal lobe
Occipital lobe
Parietal lobe
Temporal lobe
Where is the frontal lobe located?
frontal part of the cortex
Where is the occipital lobe located?
