what supplies the dark red?
what supplies the medial medulla?
anterior spinal a.
what supplies the top lateral portion of the open medulla
top of Caudal medulla
Posterior spinal a.
lateral protion from middle to rostral medulla (orange below)
Rostral Lateral medulla
includes spinal trigem, solitary nucleus, ALS, interior cerebellar peduncle
What supplies top of medulla until the fasciuli go away?
posterior spinal artery
includes gracile nulcueus, cuneate fasiculus and nucleus
What supplies olivary complex in the caudal to middle medulla?
what supplies rostral medial medulla? until when?
paramedian branches of basilar. once you get to the mouse ears
when does the posterior spinal disappear from the medulla?
by the time its only cuneate nucleus
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
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
What does AICA supply? until when?
lateral part of middle pons until the rostral pons section
superior cerebellar artery
supplies the superior cerebellar peduncle area throughout the pons
What supplies medial midbrain? for how long? (green)
paramedian branches of the basilar artery supply the midbrain all the way up
What supplies lateral portion of midbrain (blue)? for how long?
all the way up
als, ml, crus cerebri
what supplies top part of midbrain? for how long?
superior cerebellar, all the way up
supplies notably the inferior and superior colliclus
What can be damaged with AICA obstruction in the pons?
What supplies blood to the pons?
1. Basilar branches
2. Superior cerebellar artery
What features in the pons do the (paramedian) basilar branches supply blood to?

2. pyramidal tract
5. reticular formation, raphe n.
6. abduscens nuclei
What features in the pons do the superior cerebellar artery supply blood to?
superior cerebellar peduncle
mesecenphalic trigem n.
some medial lemniscus
What features in the pons does AICA supply blood to?
1. facial nucleus
2. spinal trigeminal nucleus and tract
3. vestibular nucleus
