- Glossopharyngeal nerve
- The glossopharyngeal nerve is the ninth cranial nerve. The 12 cranial nerves, the glossopharyngeal nerve included, emerge from or enter the skull (the cranium), as opposed to the spinal nerves which emerge from the vertebral column. The glossopharyngeal nerve supplies the tongue, throat, and one of the salivary glands (the parotid gland). Problems with the glossopharyngeal nerve result in trouble taste and swallowing. "Glosso-" comes from the Greek "glossa", the tongue and "pharynx" is the Greek for throat. So the glossopharyngeal nerve is the nerve that serves the tongue and throat.

* * *the ninth cranial nerves (IX), which supplies motor fibres to part of the pharynx and to the parotid salivary glands and sensory fibres to the posterior third of the tongue and the soft palate.
