Can we have a complete list of all structures derived from the Neural Crest Cells Please ? any source i come across gives an incomplete list. PLease help me out here guys ! :roll:

To Start off with ..the ones I know are:

Schwann Cells
Gangion Cells - including Adrenal Medulla
Pia and Arachnoid
C-Cells of Parathyroid
Pupillary and Ciliary Body muscles
Odontoblasts
Aortico-pulmonary septum


Are any of the glial cells derived from the neural crest ?

Melanocytes, dorsal root ganglia, peudounipolar and multipolar cells, parafollicular C cells of thyroid, laryngeal cartilage.
I beleive the glial cells comes from neuroectoderm.

I) Maxillary prominence which consist of:
Maxilla, Zygomatic, Squamous temporal bone, vomer.

Mandibular prominence consist of :
Mandible, Incus, Malleus

II) Lesser horn of Hyoid bone
Upper part of body of Hyoid bone {LUSS}
Stapes and Styloid process

III)Greater horn of Hyoid bone
Lower part of the body of Hyoid bone

Also :
I) In the face, neck, and limbs "the dermis" is from neural crest cells
II)Chromaffin cells
III)many Postganglionic neurons
IV) neurons of the enteric ganglia
V)preaortic ganglia(collateral ganglia)

There are no pneumonics that I know of but one good thing[except for Possibly the epicardium ] this completes the bulk of the list. :!:

from Neural crest:
All sensory ganglion and autonomic ganglion (including adrenal medulla, think of it as a special form of autonomic ganglion)
Pigment cells
Schwann cells
Satellite cells
Meninges (Pia and arachnoid mater)
Pharyngeal arch cartilage
Odontoblasts
Parafollicular (C) cells
Aorticopulmonary septum
Endocardial cushions
