Valve created by soft palate keeps food out of nasal airway during swallowing
<h2>Neural crest </h2>
Explanation:
The neural crest likely forms: neurons and glia of the peripheral nervous system
- The neural crest are bilaterally paired strips of cells arising in the ectoderm at the margins of the neural tube
- In the body region, neural crest cells also contribute the peripheral nervous system (both neurons and glia) consisting of sensory ganglia (dorsal root ganglia), sympathetic and parasympathetic ganglia and neural plexuses within specific tissues/organs
- The nervous system is made up of specialized cells which includes nerve cells (or neurons) and glial cells (or glia)
- Neurons are the basic functional units of the nervous system, and they generate electrical signals called action potentials, which allow them to quickly transmit information over long distances
- Glia are also essential to nervous system function, but they work mostly by supporting the neurons
