Flashcards in Neuroembryology Deck (31):
what is neurulation?
refers to the folding process in vertebrate embryos, which includes the transformation of the neural plate into the neural tube.
what is the function of the notochord?
a cartilaginous skeletal rod supporting the body in all embryonic
location of ectoderm and parts?
the outermost layer of cells or tissue of an embryo in early development, or the parts derived from this, which include the epidermis and nerve tissue.
what is the function of the neural plate?
is a key developmental structure that serves as the basis for the nervous system. Opposite the primitive streak in the embryo, ectodermal tissue thickens and flattens to become the
what is the neural groove?
is a shallow median groove of the neural plate between the neural folds of an embryo.
whats is the nueral fold?
fusion in the chick embryo is known to commence in the midbrain region before progressing cranially and caudally to involve the fore- and hindbrain regions, respectively.
what does the neural tube develop into?
central nervouse system
what does the neural crest develop into?
spinal and autonomic ganglia
what is the proencephalon?
what is the mesencephalon?
what is the rhombencephalon?
where does the telencephalon develop from?
primitive cerebral hemisphere
where does the diencephalon develop from?
where does the mesencephalon develop from?
where does the metencephalon deveop from?
where deos the myelencephalon develop from?
what does flexure bends describe?
what deos cephalic describe?
what is the location of pontine?
between the pons and cerebellum
forms the fourth ventricle
where are laeral ventricles located?
where are third ventricles located?
where is the cerebral aquaduct located?
where is the fourth ventricle located?
what does the alat plate consist of?
dorsal and sensory
what does sulcus limitans separate?
separates the cranial nerve motor nuclei (medial) from the sensory nuclei (lateral).
what does the basal plate contain?
It extends from the rostral mesencephalon to the end of the spinal cord and contains primarily motor neurons
ventral motor root
what does the alar plate?
are primarily associated with sensory functions.
what are the characteristics of the ventricular zone?
may become anything
what does the intermediate zone contain?
