Development of the brain Flashcards
there are initially 3 vesicles name them?
prosencephalon, mesencephalon, rhombencephalon
these vesicles need to bend to fit the skull, name the bends?
cervical fissure (between the spinal cord and the rhombencephalon) and the cephalic flexure (between the rhombencephalon and the mesencephalon)
the rhombencephalon splits into the?
metencephalon and myelencephalon
the prosencephalon splits into the?
telencephalon and diencephalon
the 4th ventricle comes form? the 3rd ventricle comes from?, the two lateral ventricles come from? What ventricle is missing from here?
the rhombencephalon. the diencephalon. from the telencephalon. the mesenephric aqueduct of silvias
the purpose of the ventricular system is?
to produce CSF whoch fills the ventricles and the sub arachnoid space
the brain stem is made of 3 parts, name them
medulla oblongata (from the myencephalon), the pons (metencephalon), the mesencephalon
the location of the cerebellum compared to the brain stem is? It comes from?
it is dorsal to the brain stem, it comes from the myencephalon
where is 4th ventricle ?
between the brain stem and the cerebellum
how many cranial nerves are located in the brain stem?
10 out 12
what are the 7 territories of the brain?
somatic, visceral, special visceral, special somatic sensory, somatic/brachial/visceral motor
what undergoes the book like opening?
the rhombencephalon, the metencephalon fully opens and the mylenephalon partially opens
the basal plates and alar plates change direction from what to what? This opening causes the formation of?
ventral and dorsal to medial and lateral. it causes the formation of ventricle 4th
the roof palate if the 4th ventricle connects with the?
pia mater and this forms the tele coroidea where the CSF will be synthesized
most of the specific nuclei of the brain stem derive from which plate?
the alar plate
