(31 cards)
what are the two lateral ventricles divided by
septum pellucidum
cerebral aqueduct
smallest part of ventricular system
associated with the midbrain
rhomboid fossa
located behind the pon
what CN comes off of the brain itself
I and II
what CN comes off of midbrain
III, IV
what CN come off of pons
V, VI, VII, VIII
what CN comes off of medulla
IV, X, XI, XII
pyramids
consist of long motor tracts running down from cerebrum to rest of body
where are cerebral peduncles located
above pons
what does interpeduncular fossa contain
CN III exit
mammary bodies
infundibulum
what is the infundibulum close to
optic chaism
what are the corpora quadrigemini
2 superior colliculi
2 inferior collilculi
where is epithalamus located
above colliculi
where does CN IV come out below
below the colliculi
middle cerebellar peduncle
connects cerebellum to pons
superior cerebellar peduncles
connect midbrain to cerebellum
inferior cerebellar peduncles
connect medulla to cerebellum
what is located in the rhomboid fossa
facial colliculus
what trigones are found in the medulla
hypoglossal and vagal
what tubles are located lateral to sulcus
gracile and cuneate
sulcus limitans
helps identify structures midline vs laterally
what is fourth ventircle assocaited with
pons
what is the central canacel associated with
medulla
tegementum
posterior to basialar region
assocaited with all 3 parts of brainstem
