Most peripheral nervous system cells in vertebrates develop from the neural crest.

The neural crest is a tissue that forms during early vertebrate development.

Part of the nervous system outside the brain and spinal cord.

The process by which vertebrate embryos grow.

Clusters of neurons that carry sensory information.

Part of the autonomic nervous system for regulating body function.

Part of the adrenal gland involved in stress response.

Nervous system of the gut, independent of the CNS.

The formation of the neural crest, a group of cells that migrate and differentiate to form various tissues and structures in the developing nervous system.

A hollow structure that forms the central nervous system (brain and spinal cord).

A stage of embryonic development where the blastula rearranges into a multilayered structure (gastrula).

A thickened region of the ectoderm that gives rise to the neural tube.

The primitive gut of an embryo.

An early stage of embryonic development, characterized by a hollow ball of cells.

One of the three primary germ layers of the embryonic disc.

The process of neural tube formation

A transparent region in the early chick embryo that contains a fluid-filled cavity.

An opaque region surrounding the area pellucida in the early chick embryo.

The single-cell-thick layer of epithelial cells in the early chick embryo that forms the three germ layers.

A crescent-shaped ridge of cells that forms in the posterior area pellucida of the chick embryo.

A structure that forms along the midline of the chick embryo during gastrulation, arising from the movement of epiblast cells.

A bulge at the anterior end of the primitive streak in the chick embryo that has important organizing functions.

The process of germ layer formation in the chick embryo, involving the ingression of epiblast cells and the formation of the primitive streak and Hensen's node.

Cells within Hensen's node that are destined to become the notochord.
