|
|
Term
| the neural tissue of the brain is biochemically isolated from the general circulation by the: |
|
Definition
|
|
Term
| the layers that make up the cranial meninges are: |
|
Definition
| the cranial dura mater, cranial arachnoid mater, and pia mater. |
|
|
Term
| this cranial meninge consists of outer and inner fibrous layers with no epidural space superficial to itself. |
|
Definition
|
|
Term
| this cranial meninge consists of the arachnoid membrane (an epithelial layer) and the cells and fibers of the arachnoid trabeculae that cross the subarachnoid space to the pia mater. |
|
Definition
|
|
Term
| this cranial meninge sticks to the surface of the brain, anchored by the processes of astrocytes. It extends into every fold and accompanies the branches of cerebral blood vessels as they penetrate the surface of the brain to reach internal structures: |
|
Definition
|
|
Term
| a fold of dura mater that projects between cerebral hemispheres in the longitudinal fissure: |
|
Definition
|
|
Term
| protects the cerebellare hemispheres and separates them from those of the cerebrum. |
|
Definition
|
|
Term
| the _________ lies within the tentorium cerebelli. |
|
Definition
|
|
Term
| divides the two cerebellar hemispheres along the midsagittal line inferior to the tentorium cerebelli. |
|
Definition
|
|
Term
| what protects the brain in case of serious cranial trauma? |
|
Definition
| the cranial meninges and CSF |
|
|
Term
| at the _______ plexus, ependymal cells secrete CSF into ventricles. |
|
Definition
|
|
Term
| lateral apertures, median aperture, subarachnoid space |
|
Definition
|
|
Term
|
Definition
| "water on the brain" is a problem seen in infants that have a problem with the reabsorption of CSF. |
|
|
Term
| a cerebrovascular accident (CVA) happens when: |
|
Definition
| the blood supply to a portion of the brain is shut off. affected neurons begin to die in a matter of minutes. (aka a stroke) |
