Name: neural crest cell
Synonyms: neural crest cells
Definition: A cell of the neural crest. The neural crest is a strip of specialized ectoderm, the neural plate border, which flanks each side of the embryonic neural plate. Neural crest cells are multipotent. Premigratory neural crest cells are found at the neural plate boarder, some of which will undergo ectomesenchymal transition and delamination to form migratory neural crest cells. Most of the cranial and all of the spinal sensory ganglion cells arise by differentiation of neural crest cells.

Name: lacks parts or has fewer parts of type
Synonyms: loss of
Definition: The bearer of this quality has_part < n of the indicated entity type, where n is the normal amount for a comparable organism. Note that the bearer of the quality is the whole, not the part. Formally: If a bearer entity e has fewer parts of type X at time t, then the number of instances x of X at t such that x part_of e is < n, where n is either the normal number for comparable entities, or n is stated explicitly. This case includes the limit case, where the bearer lacks all parts of the specified type.

Name: filopodium
Synonyms:
Definition: Thin, stiff, actin-based protrusion extended by the leading edge of a motile cell such as a crawling fibroblast or amoeba, or an axonal or dendritic growth cone, or a dendritic shaft.
