pterygopalatine ganglion
Alveolar
branches of superior maxillary nerve and sphenopalatine ganglion. (Testut.)
Plan of the
facial and intermediate nerves and their communication with other nerves.
Sympathetic
connections of the sphenopalatine and superior cervical ganglia.
The pterygopalatine ganglion is one of four parasympathetic ganglia of the head and neck and largest of the peripheral parasympathetic ganglia. It receives parasympathetic fibers from the facial nerve.
Gross anatomy
- located in the pterygopalatine fossa
- anterior to opening of the pterygoid canal and foramen rotundum
- adjacent to the sphenopalatine foramen
- it supplies parasympathetic fibers to the lacrimal gland and mucosal glands in the nose, nasopharynx, sinuses and soft palate
Roots
- parasympathetic root
- superior salivary nucleus via the greater petrosal nerve
- nerve of pterygoid canal from the nervus intermedius component of the facial nerve.
- sympathetic root
- superior cervical ganglion via the internal carotid nerve
- deep petrosal nerve
- nerve of the pterygoid canal
- sensory root
- trigeminal ganglion via the maxillary nerve
Branches
- nasopalatine nerve
- posterior superior nasal nerves
- greater palatine nerve
- lesser palatine nerves
- pharyngeal nerve
