The pterygopalatine ganglion (also known as the nasal ganglion, or sphenopalatine 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
ganglionlocated in the pterygopalatine fossa
anterior to opening of the pterygoid canal and foramen rotundum, adjacent to the sphenopalatine foramen
receives preganglionic parasympathetic neurones from the greater superficial petrosal nerve (from superior salivatory nucleus in the pons) 5
also receives ganglionic branches from the maxillary branch of the trigeminal nerve 5
it supplies parasympathetic fibres to the lacrimal gland and mucosal glands in the nose, nasopharynx, sinuses and soft palate
