Answer 5

Surrounds optic chiasm

Question 6

Vertebral arteries

Answer 6

Meet at the midline along the ventral surface of the pons
Called the basilar artery
Top of basilar artery

Question 7

Answer 8

Supplies blood to posterior parts of the cerebellum

Question 9

Anterior inferior cerebellar artery AICA

Question 10

CSF is in…

Answer 10

Ventricles and around the brain

Question 11

Dura matter

Answer 11

tough collagenous membrane, firmly attached to the inner surface of the skull

Question 12

Pia

Answer 12

Thin layer that follows the contours of the brain

Question 13

Arachnoid

Answer 13

Thin layer of cells attached to dura

Question 14

In the subarachnoid space, strands of collagen connective tissue called trabeculae extend into pia forming a scaffolding that holds the brain in place

Question 15

Subarachnoid space

Answer 15

Subarachnoid space contains CSF as well as arteries that supply blood to the brain

Question 16

Dura matter separates into two

Answer 16

One along surface and other down into longitudinal fissure (b/w 2 hemispheres)

Question 17

Separation of dura matter

Answer 17

Falix cerebri

Question 18

CSF flows out through little opening

Question 19

Superior sagittal sinus

Answer 19

Separation of two leaflets form a triangular tube

Question 20

Superior sagittal sinus

Answer 20

Venous blood flows in caudally and converges with straight sinus at the confluence of the sinuses in the back of the brain and ultimately leaves the skull throught internal jugular vein

Question 21

Brian contains network fluid-filled spaces called ventricles

Answer 21

CSF produced in the ventricles by spcialized tissue called choroid plexus

Question 22

Lateral ventricle

Answer 22

anterior, posterior and inferior ventral horns

Question 23

How to lateral ventricles connect to the 3rd ventricles

Answer 23

foramen of Monro

Foramen of Lushka and Foramen of Magendie

Answer 25

CSF flows out of the 4th ventricle through lateral and caudal openings called

Question 26

Arachnoid villi

Answer 26

Superior sagittal sinus , valve-like structures that CSF flows into

Question 27

Arachnoid granulations

Answer 27

Villi cluster to form macroscopically visible structures
