The '''Trunk Neural Crest''' refers to a group of [[neural crest]] cells that migrate from the neural tube during the embryonic development of vertebrates. These cells are unique in their multipotency, capable of differentiating into a variety of cell types, including [[neurons]], [[glial cells]], [[melanocytes]], and [[adrenal medulla]] cells.

The trunk neural crest cells play a crucial role in the formation of the [[peripheral nervous system]]. They give rise to the [[dorsal root ganglia]], which contain the cell bodies of sensory neurons. They also contribute to the formation of the [[sympathetic nervous system]], producing the [[sympathetic ganglia]] and the adrenal medulla.

The trunk neural crest is a population of cells that originates from the neural crest during embryonic development. These cells are crucial for the formation of various structures in the body.

Development[edit]

The trunk neural crest cells emerge from the dorsal part of the neural tube and migrate to different parts of the embryo. They differentiate into a variety of cell types, including:

Migration[edit]

Trunk neural crest cells follow specific migratory pathways to reach their destinations. These pathways are influenced by various molecular signals and extracellular matrix components.

Function[edit]

The trunk neural crest is essential for the development of the peripheral nervous system. It contributes to the formation of the autonomic nervous system, which regulates involuntary bodily functions.

Clinical Significance[edit]

Defects in trunk neural crest development can lead to various medical conditions, such as:
