The pterygopalatine ganglion is one of four parasympathetic ganglia of the head and neck and largest of the peripheral parasympathetic ganglia. It receives parasympathetic fibres 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 fibres 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
