Neurological Considerations Flashcards
development of the nervous system begins around what week of embryonic development
third
the process of nervous system development starts with the thickening of this outer tissue layer of the embryo
ectoderm
the ectoderm thickens to form the __ __
neural plate
as the neural plate begins to fold inward it greats the
neural groove
what are the sides of the neural groove called
neural folds
by the end of this week the neural folds begin to fuse
third
by the end of this week the neural folds have completely fused to form the neural tube
forth
what structures with the neural tube eventually become
the brain and spinal cord
what are the three primary vesicles of the neural tube
prosencephalon, mesencephalon, rhombencephalon
the future cerebrum
prosencephalon
the future midbrain
mesencephalon
the future brainstem and cerebellum
rhombencephalon
name the two parts the prosencephalon divides into
telencephalon and diencephalon
future cerebral hemispheres
telencephalon
future thalamus, hypothalamus, and other structures
diencephalon
the rhombencephalon divides into
mesencephalon and myelencephalon
future pons and cerebellum
mesencephalon
future medulla
myelencephalon
