12. pons

a. looks like a \butt\
b. thin covering over the entire brain
c. part of the brain found at the back, resembles cauliflower
d. raised ridges of the brain
e. fluid filled space above the thalamus and below the fornix
f. the nub just above the superior and inferior colliculi
g. fluid filled space between the corpus callosum and the fornix
h. nerves that cross each other on the underside of the brain
i. circular region in the center of the brain (relay station)
j. rounded part of the brain stem
k. separates the third ventricle from the lateral ventricle
l. \tree of life\ within the cerebellum

Explanation:

1. Arbor Vitae is the "tree of life" within the cerebellum.
2. Superior colliculi are related to visual - reflex functions and don't match the given "butt" description.
3. Lateral ventricle is a fluid - filled space above the thalamus and below the fornix.
4. Optic chiasma are nerves that cross each other on the underside of the brain.
5. Dura Mater is a thick, tough outer - covering of the brain, not a thin covering over the entire brain.
6. Pineal gland is a small endocrine gland in the brain, not well - described by the given options.
7. Thalamus is a circular region in the center of the brain (relay station).
8. Cerebellum is part of the brain found at the back, resembles cauliflower.
9. Fornix is a structure in the brain, not well - described by the given options.
10. Gyrus are raised ridges of the brain.
11. Third ventricle is a fluid - filled space, not well - described by the given options.
12. Pons is a rounded part of the brain stem.
