Placode

Posted byBrian Hopkins May 22, 2019

Local thickening in the embryonic ectodermal layer in the early embryo.  The cells of the placed ordinarily constitute a primordial group from which a sense organ (e.g., lens placode) or neurons of sensory ganglia will be derived. Other parts of these ganglia arise from the neural crest.
