Question 9

what supplies rostral medial medulla? until when?

Answer 9

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

Question 10

when does the posterior spinal disappear from the medulla?

Answer 10

by the time its only cuneate nucleus

Question 11

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

Answer 11

when CN 8 comes in

replaced by paramedian branches of basilar

in rostral medulla when CN 8 comes in

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