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 | edit source]
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:
- Sensory neurons of the dorsal root ganglia
- Sympathetic neurons
- Schwann cells
- Melanocytes
- Cells of the adrenal medulla
Migration[edit | edit source]
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 | edit source]
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 | edit source]
Defects in trunk neural crest development can lead to various medical conditions, such as:
