What is the pterygopalatine ganglion?
The pterygopalatine (sphenopalatine) ganglion is one of four small parasympathetic ganglia found in the head. Although it is described as being a parasympathetic ganglion, it also carries sympathetic and sensory fibers to the nasal, oral and pharyngeal regions of the head.
Is pterygopalatine ganglion same as sphenopalatine ganglion?
The pterygopalatine ganglion (also known as the sphenopalatine ganglion or, more rarely, the nasal ganglion or Meckel’s ganglion; Larsell and Fenton, 1928; Gloster, 1961) lies deep within the pterygoid fossa, rostral to the anterior opening of the pterygoid canal and inferior to the maxillary nerve (Kuntz, 1945; …
What does the ciliary ganglion do?
Nerves from the ciliary ganglion innervate the muscles that constrict the pupil, a hole in the iris that lets light enter the eye. Other fibers from the ciliary ganglia go to muscles that control the shape of the lens in the eye.
What are the clinical effects of irritation of pterygopalatine ganglion?
Clinical Significance The pterygopalatine ganglion is theorized to be a component for a group of headache disorders classified as trigeminal autonomic cephalalgias (TACs) which present as unilateral headaches with ipsilateral autonomic features (lacrimation, rhinorrhea, nasal congestion, eyelid edema, and ptosis).

What causes sphenopalatine ganglion pain?
The implication of the sphenopalatine neurons in producing pain in remotely located sites is likely related to the anatomical connections that play a pivotal role as a relay center of the autonomic nervous system. The superior cervical sympathetic ganglion has a connection with the upper cervical nerve roots.
What does pterygopalatine ganglion innervate?
The pterygopalatine ganglion neurons innervate the lacrimal glands, the blood vessels of the eye, the blood vessels and secretory glands of the nasal cavity and palate, and the cerebral blood vessels.

What nerves go through ciliary ganglion?
As it continues anteriorly, its path runs between the superior oblique and medial rectus muscles and in the process gives off five branches: sensory root of the ciliary ganglion, long ciliary nerves, posterior ethmoidal nerve, anterior ethmoidal nerve, and infratrochlear nerve.
