Flashcards in Early development of the ectoderm Deck (21)
What is the prochordal plate?
An area at the cephalic end of the embryo where the ectoderm and endoderm fuse - this will become the bucopharyngeal membrane
What is the cloacal plate?
An area at the caudal end of the embryo where the ectoderm and endoderm fuse - this will become the coacal membrane
What develops from the proencephalon?
The telencephalon (cerebral cortex) and diencephalon (hypothalamus, thalamus, epithalamus)
What is the proencephalon?
What is the mesencephalon?
What is the rhombencephalon?
What develops from the rombencephalon?
The metancephalon and the myencephalon
What develops from the telencephalon?
The cerebral cortex
Which embryonic structure does the cerebral cortex develop from?
Which embryonic structure does the hypothalamus develop from?
What develops from the diencephalon?
Hypothalamus, epithalamus, thalamus
Which structures develop from the metencephalon?
The pons and cerebellum
Which structures develop from the myencephalon?
The medulla oblongata
Which embryonic structure does the medulla oblongata develop from?
Which embryonic structure does the pons develop from?
Which embryonic structure does the cerebellum develop from?
What is the difference between the metencephalon, myelencephalon and mesencephalon?
Metencephalon - pons and cerebellum
Myencephalon - medulla oblongata
Mesencephalon - mid brain
What is the role of the notochord?
It promotes the formation of neuroectoderm (the neural plate) and therefore the formation of the neural tube
How is the notochord formed?
Cells migrate from the primitive node to form the notochordal plate which folds to form the notochord
The process in embryology that describes the formation of the spinal cord and brain
