Answer 5

Interventricular foramen of MONRO

Question 6

Answer 6

Third ventricle

Question 7

The 3rd ventricle communicates with the 4th ventricle via the…

Answer 7

cerebral aqueduct of Sylvius

Question 8

This located between in the pons and MEDULLA?

Answer 8

Fourth ventricle cavity

Question 9

What is continuous with the central canal of the medulla, which, in, turn, is continuous with the central canal of the spinal cord?

Answer 9

Forth ventricle

Question 10

The 4th ventricle opens by means of one median and two lateral apertures into the __________________. These apertures are the only means by which the CSF formed in the ventricles enter the ________________________.

Answer 10

Subarachnoid space

Question 11

What produces CSF?

Answer 11

CHOROID PLEXUS

Question 12

Certain sites in the ventricles are lined with ___________________?

Answer 12

CHOROID PLEXUS

Question 13

What is clear, colorless, acellular fluid, similar to blood plasma?

Answer 13

CSF

Question 14

What are the function of CSF?

Answer 14

1) To cushion and support the brain and spinal cord
2) As a lymphatic system
3) As an environment for neurons

Question 15

What is the course of CSF follows?

Answer 15

1) CSF is formed in the two lateral ventricles by the CHOROID PLEXUS
2) It passes through the interventricular foramen of Monro
3) It joins the CSF produced in the 3rd ventricle
4) It passes through the cerebral aqueduct of SYLVIUS
5) It joins with the CSF produced in the 4th ventricle
6) It passes through the apertures of the fourth ventricle into the SUBARACHNOID SPACE
7) it then travels upward around the brain and downward around the spinal cord
8) the fluid circulates and eventually enters the arachnoid granulations, where CSF is reabsorbed and passes through the lateral lacunae to drain into the SUPERIOR sagittal sinus and finally into the venous system of the body
