What nerves pass through the Pterygopalatine ganglion?
What nerves pass through the Pterygopalatine ganglion?
The pterygopalatine ganglion gives rise to the following nerves: the nasopalatine nerve, the lesser palatine nerve, the greater palatine nerve, the posterior superior lateral nasal nerves, the posterior inferior lateral nasal nerves, and pharyngeal nerve.
What does nasopalatine nerve branch from?
Also known as nervus incisivus, the nasopalatine nerve is a division of the maxillary branch of the trigeminal nerve. Its function is to provide sensation to the anterior palate. The sphenopalatine artery supplies the same area it innervates.
What does the nasopalatine nerve innervate?
The nasopalatine nerve innervates the anterior part of the hard palate and the mucosa of the nasal septum. A nasopalatine nerve block may be used as local anesthesia for some dental procedures, though it is often painful for the patient.
Where is the sphenopalatine ganglion located?
pterygopalatine fossa
The sphenopalatine ganglion (pterygopalatine, nasal, or Meckel’s ganglion) is a parasympathetic ganglion that is located in the pterygopalatine fossa (Fig. 11-8A), posterior to the middle turbinate. Its sensory root is derived from sphenopalatine branches of the maxillary nerve, cranial nerve (CN) V2.
What cranial nerve provides Preganglionic Parasympathetics to the pterygopalatine ganglion?
*Greater Petrosal Nerve: Here, the preganglionic parasympathetic nerve fibers synapse in the aptly named pterygopalatine ganglion. The postganglionic parasympathetic fibers then join branches of the V2 division of CN V and provide innervation to: Lacrimal glands.
What is Pterygopalatine fossa?
The pterygopalatine fossa (PPF) is a cone-shaped depression deep to the infratemporal fossa and posterior to the maxilla on both sides of the skull. The fossa is located between the pterygoid process and the maxillary tuberosity, close to the orbital apex.
Is pterygopalatine and sphenopalatine ganglion?
The pterygopalatine ganglion (aka Meckel’s ganglion, nasal ganglion, or sphenopalatine ganglion) is a parasympathetic ganglion found in the pterygopalatine fossa….

Is the pterygopalatine ganglion sympathetic?
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.
What is the Pterygopalatine ganglion?
What is the nasopalatine nerve?
The nasopalatine nerve (also known as the long sphenopalatine nerve) is a branch of the maxillary division of the trigeminal nerve and contributes to the pterygopalatine ganglion. The nasopalatine nerve divides off the maxillary division just after emerging from the foramen rotundum to enter the pterygopalatine fossa.
What is the scientific name for the pterygopalatine nerve?
Anatomical terms of neuroanatomy. [edit on Wikidata] One branch of the pterygopalatine ganglion (trigeminal nerve, maxillary branch), longer and larger than the others, is named the nasopalatine nerve (sometimes called the long sphenopalatine nerve).
Where is the pterygopalatine ganglion located?
The pterygopalatine ganglion sits in the recess area of the skull called the pterygopalatine fossa, near an opening in the skull called the sphenopalatine foramen, and just below the maxillary nerve where it crosses the fossa. The ganglion itself is enclosed in a capsule of reddish-gray connective tissue.
What are the branches of the sphenopalatine ganglion?
The sphenopalatine ganglion and its branches. (Termination of nasopalatine nerve labeled at bottom left.) [edit on Wikidata] One branch of the pterygopalatine ganglion (trigeminal nerve, maxillary branch), longer and larger than the others, is named the nasopalatine nerve (sometimes called the long sphenopalatine nerve).
