|
the area of the brain between the midbrain and the medulla
connects the cerebellum to the CNS |
|
Diencephalon
|
area of the brain between the cerebral hemispheres and the midbrain

|
Cerebellum means:
|
little brain
|
|
Dura matter is the:
|
thickest, toughest and outermost layer of the meninges
|
|
Matter means:
|
mother
referring to the protective function |
|
Dura:
|

|
Meninges has (3) layers:
|
Dura mater (outermost)
Arachnoid mater (middle) Pia mater (innermost) |
|
Arachnoid mater is the:
|
loosely attached to the deepest of the meniges by weblike fibers
allows space for movement of CSF between layers |
|
Pia mater is the:
|
innermost layer
attached to the nercous tissue of the brain/spinal cord |
