Embryonic Connective Tissue and Neural Crest Cells Quiz

Ectomesenchyme = Connective tissue formation in the head region Neurocristopathies = Diseases caused by abnormal generation, migration, or differentiation of neural crest cells Neural crest cells = Multipotent progenitor cells that migrate and develop into various cells and tissues throughout the body Mesoderm = The origin of embryonic connective tissue elsewhere except in the head region

Peripheral nervous system = Derived from neural crest cells Melanocytes of the skin = Derived from neural crest cells Smooth muscles of intracranial blood vessels = Derived from neural crest cells Thyroid gland parafollicular cells = Derived from neural crest cells

Multipotent progenitors = Ability to differentiate into various cell types Migration = Ability to move to different locations in the body Differentiation into mesodermal-type cells = Capability despite originating from ectoderm Differentiation into endodermal-type cells = Capability despite originating from ectoderm
