The outermost meninge (the furthest) away from the brain and spinal cord is the:
Dura mater
The middle meninge surrounding the brain and spinal cord is called the:
Pia mater
What separates the arachnoid mater from the pia mater?
The subarachnoid space which contains the CSF.
The pia mater holds tight (hugs) to the:
Brain and spinal cord.
In the brain, the dura mater attaches to the:
Periosteum of the skull bone
In the spinal cord, the dura mater is found close to the walls of the:
Vertebral foramen
What fluid lies between the subarachnoid mater and pia mater?
Cerebrospinal fluid
What clear fluid is found in the ventricles of the brain?
Cerebrospinal fluid
Cerebrospinal fluid is made by what neuroglial cell?
Ependymal cell
What is the purpose of CSF in the brain?
• Bring nutrients such as glucose and protein to the brain’s cells. • Remove wastes created by neurons and neuroglial cells. • Cushions the brain and protects it from minor jolts or blows to the head
Inflammation of the coverings of the spinal cord and brain is called:
Meningitis
In addition to the CSF found in the meninges, what other brain structure contains CSF?
The ventricles of the brain
What neuroglial cell lines the ventricles and filters blood plasma to make cerebrospinal fluid?
Ependymal cells
What is the function of the BBB (blood brain barrier)?
Regulates what substances can move from the bloodstream into the brain’s tissue fluids.
What neuroglial cell maintains the BBB (blood brain barrier)?
Astrocytes
Chemotherapy for brain tumors is difficult because of the _____________________.
Blood brain barrier
Three letter acronym “CSF” stands for _______.
Cerebrospinal fluid
The chamber in the brain where CSF is found is called the _______________.
Ventricle
