Primary and Secondary Vesicles of the Brain and Differentiation Flashcards
primary vesicles of the brain
prosencephalon, mesencephalon, rhombencephalon
prosencephalon gives rise to
telencephalon and diencephalon
telencephalon gives rise to what structures CN
forebrain, CN I
telencephalon neural canal regions
lateral ventricles separated by septum pellucidum
diencephalon gives rise to structures and CN
thalamus, hypothalamus, pineal, retina, mam body, post pit CN II
diencephalon neural canal regions
foramen of monroe (aka interventric foramen) = 1&2 to 3rd ventricle
mesencephalon structures and CN
midbrain CN III, IV
mesencephalon neural canal regions
cerebral aqueduct of sylvius
rhombencephalon gives rise to
metencephalon and myelencephalon
metencephalon gives rise to structures and CNs
PONS and cerebellum CN V, VI, VII, VIII
myelencephalon gives rise to ? structure and CNs
medulla oblongata CN IX, X, XI, XII
met and myelencephalon neural canal regions
4th ventricle
median aperture (1)
foramen of magendie
lateral apertures (2)
foramina of luschka
arterial anastomosis around the pituitary gland and optic chiasm supply of blood between forebrain and hindbrain
circle of willis
arteries which supply circle of willis
internal carotid and vertebral arteries
arteries which make the circle of willis
anterior and posterior cerebral, anterior and posterior communicating
MC location for cerebral vascular accident (CVA); carries more blood than other arteries (~800mL/min)
middle cerebral artery
aka anterior spinal artery; sends 200 branches into ventral aspect of cord
anteromedial longitudinal artery trunk AMLAT
aka posterior spinal artery; branches provide blood to posterior roots of spinal cord
posterolateral longitudinal artery trunks (PLLAT)
