Question 17

The optic nerves pass through which foramina?

Answer 17

optic canal

Question 18

the optic chasm is superior to which bone of the skull?

Answer 18

Sella turica

Question 19

dura mater

Answer 19

the outermost of the meninges, very strong membrane which is firmly attached to the inside of the skull and contains blood vessels which nourish the bone

Question 20

fall cerebri

Answer 20

a missagittal fold of the dura mater, extends to the longitudinal fissure of the cerebrum and prevents lateral or side-to-side movement of the cerebral hemispheres within the skull.

Question 21

tentorium cerebelli

Answer 21

horizontal fold of the dura mater, extends into the horizontal fissure which separates the occipital loves of the cerebrum form the cerebellum, supporting the wight of the occipital loves and limiting vertical movement of the brain.

Question 22

arachnoid mater

Answer 22

middle layer, bridges over sulk of the cerebral cortex but follows the surface of the brain into larger fissures

Question 23

pia mater

Answer 23

the deepest of the three, firmly attached to nervous tissue of the brain and follows all of its convulsion into and out of sulk and fissures

Question 24

epidural space

Answer 24

lies between the bone of the skull and the dura mater

Question 25

the subdural space

Answer 25

lies between the dura mater and the arachnoid mater

Question 26

subarachnoid space

Answer 26

lies between the arachnoid mater and the pia mater, contains cerebrospinal fluid

Question 27

three layers of meningitis and three related space in order

Answer 27

``` epidural space dura mater subdural space arachnoid mater subarachnoid space pia mater ```

Question 28

neural plate

Answer 28

flattened region of cells in the developing embryo

Question 29

neural tube

Answer 29

the neural plate invaginate and folds over to form the neural tube

Question 30

flow of CFS

Answer 30

1. secreted by choroid plexus in lateral ventricle 2. flows through the inter ventricular foramina into third ventricle 3. choroid plexus in the third ventricle adds more CSF 4. flows down the cerebral aqueduct to the fourth ventricle 5. choroid plexus in fourth ventricle adds more CSF 6. flows out two lateral apertures and one median aperture 7. fills subarachnoid space 8 arachnoid villi reabsorbs into venous blood of dural sinuses.

Question 31

what connects the brain to the pituitary gland?

Answer 31

infundibulum
