The Nervous System Questions: Cerebrospinal Fluid?

Cerebrospinal fluid is formed by the capillary knots called 1.____, which hang into the 2.____ of the brain. Ordinarily, cerebrospinal fluid flows from the lateral ventricles to the third ventricle and then through the 3.____ to the fourth ventricle. Some of the fluid continues down the 4.____ of the spinal cord, but most of it circulated into the 5.____ by passing through three tiny openings in the walls of the 6.____. As a rule, cerebrospinal fluid is formed and drained back into the venous blood at the same rate. If its drainage is blocked, a condition called 7.____ occurs, which results in increased pressure on the brain.
Any answers would be appreciated, I left my physiology/anatomy book in my locker and it’s a study guide for a quiz tomorrow :\

Autonomic Nervous System? Please Please Help. Hard Questions…?

you do can you please e mail me? I have a study guide and I cannot figure out some of the questions and need help before my test tomorrow.
.
1) What nerve roots innervate the sympathetic division.
2) Which spinal segments have gray communicants?which have white rami?
3) which nerves carry most of the parasympathetic division?
4) What are the differences in the pre and post ganglionic fibers in each division? what are the difference in their ganglia?
also… where can I find a picture that allows me to trace a pathway through white and gray communicantes and the various ganglia
A picture that allows me to trace a preganglionic fiber from the spinal cord to the adrenal medulla
and finally a picture that will allow me to trace sympathetic innervation of the eye
