Nervous System Embryology GBA Flashcards
Prosencephalon Gives?
Diencephalon and Telencephalon
Mesencephalon Gives?
Still Mesencephalon - Midbrain
Rhombencephalon Gives?
Myelencephalon and Metencephalon
Cephalic Flexure:
Between Prosencephalon and Rhombencephalon
Cervical Flexure:
Between Medulla Spinalis and Rhombencephalon
Diencephalon Gives?
Epithalamus, Subthalamus, Thalamus, Hypothalamus, Mammillary Bodies, Neurohypophysis, Pineal Gland, GLOBUS PALLIDUS, Optic Vesicle.
Telencephalon Gives?
Cerebral Hemispheres, Caudate and Putamen
Myelencephalon?
Medulla Oblongata
Metencephalon?
Pons and Cerebellum
Glioblasts, Migrate where? and Forms what?
Intermediate Zone and Marginal Zone of Neural Tube
Gives Astrocytes and Oligodendrocytes
So Marginal Zone gives White Matter
Neuroblasts, Migrate where? and Forms what?
Intermediate Zone of Neural Tube
Gives Neurons
So Intermediate Zone Gives Grey Matter
What happens to the cells not migrating like neuro- and glioblasts?
Stay in the Ventricular Zone and Form:
Ependymocytes
Tanycytes
Choroid Plexus Cells
Basal Plate gives?
Ventrolateral thickening that form Ventral and Lateral Horns of Grey matter - Autonomic and Motor Neurons
Alar Plate gives?
Dorsolateral thickening that form Dorsal Horns of Grey matter - Sensory Neurons
Sulcus Limitans?
Where is the Remnant if it?
Limit between Alar Plate and Basal Plate
Remains in Rhomboid Fossa
