Embryology Of The Nervous System Flashcards
(11 cards)
What are the three primary vesicles?
Prosencephalon
mesencephalon
rhombencephalon
The prosencephalon matures into what two secondary vesicles?
Talencephalon and diencephalon
The telencephalon forms, what adult structure and what ventricle?
Cerebrum and lateral ventricle
The diencephalon forms, what adult structure and ventricle?
The thalamite( epithalmus, hypothalamus and thalamus)
Third ventricle
The mesencephalon forms what secondary vesicle and what adult structure and ventricle?
Mesencephalon-> mesencephalon (doesn’t divide) -> midbrain and cerebral aqueduct
The rhombencephalon divides to form what two secondary vesicles?
Metencephalon
Myelencephalon
The metencephalon forms, what two adult structures and what ventricle?
Pons and cerebellum
Fourth ventricle
The myelencephalon forms, what two adult structures and what ventricle?
Medulla and spinal cord
Central canal
What’s the mnemonic to remember all the secondary vesicles in neurodevelopment?
“Tel, Di, Mes, Met, My”
What does the neural tube form?
The central nervous system
What does the neural crest form?
The peripheral nervous system
