|
Which vitamin is important in formation of neural tube and what happens if there isn't enough of this? |
Folic acid Neural Tube Defects |
|
|
True or false Anencephaly occurs because of neural pores not being closed at the caudal end. |
False, Improper closure occurs at the caudal end |
|
|
What causes spina bilfida? |
Improper closure of the neural tube |

|
What are the three meninges of the spinal cord called and in which order? |
- Pia meter - Arahoid - Duramater |
|
|
Which fluid flows in the central canal, brain ventricles and the subarachnoid space?
|
Cerebrospinal fluid (CFS) |
|
|
Which of these are true? a) CFS provides mechanical support for the brain b) CFS reduces the weight of the brain and spinal cord c) CFS fluid can be used to diagnose state of the CNS D) CFS can be obtained by a puncture between L1-L2 |
a - c are true d is false. CFS can be obtained from L3-L4. This is because there is no spinal cord here. It is finished developing before the body is developed. |
|
|
