1

what supplies the dark red? 

anterior spinal

2

what supplies the medial medulla?

anterior spinal a. 

3

what supplies the top lateral portion of the open medulla

pica

4

Blue?

top of Caudal medulla

Posterior spinal a. 

5

Green?

Vertebral a.

6

lateral protion from middle to rostral medulla (orange below)

Rostral Lateral medulla

PICA

includes spinal trigem, solitary nucleus, ALS, interior cerebellar peduncle

7

What supplies top of medulla until the fasciuli go away?

posterior spinal artery

 includes gracile nulcueus, cuneate fasiculus and nucleus

8

What supplies olivary complex in the caudal to middle medulla?

vertebral 

9

what supplies rostral medial medulla? until when?

paramedian branches of basilar. once you get to the mouse ears

10

when does the posterior spinal disappear from the medulla?

by the time its only cuneate nucleus

11

when does the anterior spinal replaced? what replaces it to feed middle rostral medulla?

when CN 8 comes in

replaced by paramedian branches of basilar

12

when does AICA first appear?

in rostral medulla when CN 8 comes in

in the medulla it just supples dorsal cochlear nucleus and the CN 8

13

What does AICA supply? until when?

AICA

lateral part of middle pons until the rostral pons section

14

purple

superior cerebellar artery  

supplies the superior cerebellar peduncle area throughout the pons 

15

What supplies medial midbrain? for how long? (green)

paramedian branches of the basilar artery supply the midbrain all the way up

16

What supplies lateral portion of midbrain (blue)? for how long?

PCA

all the way up

als, ml, crus cerebri

17

what supplies top part of midbrain? for how long?

superior cerebellar, all the way up

supplies notably the inferior and superior colliclus
