Flashcards in Neuroembryology Deck (31):
1

what is neurulation?

refers to the folding process in vertebrate embryos, which includes the transformation of the neural plate into the neural tube.

2

what is the function of the notochord?

a cartilaginous skeletal rod supporting the body in all embryonic

3

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.

4

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

5

what is the neural groove?

is a shallow median groove of the neural plate between the neural folds of an embryo.

6

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.

7

what does the neural tube develop into?

central nervouse system

8

what does the neural crest develop into?

PNS
schwann cells
spinal and autonomic ganglia
adrenal glamd

spinal chord
what does the alat plate consist of?

dorsal and sensory

26

what does sulcus limitans separate?

separates the cranial nerve motor nuclei (medial) from the sensory nuclei (lateral).

27

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

28

what does the alar plate?

are primarily associated with sensory functions.

doral horn

29

what are the characteristics of the ventricular zone?

stem cell
may become anything

30

what does the intermediate zone contain?

blast cells

31

what are characteristics of the marginal zone?

everything is mature
mature glial
mature neurons
