What is the pterygopalatin ganglion?
Pterygopalatin ganglion is a collection of cells located in pterygopalatin fossa. It is identified as one of the four parasympathetic ganglias that can be found in the head and neck. The ganglion of pterygopalatin is also referred to as Meckel's Ganglion, named after the German anatomistic anatomy of the 18th century, Johann Friedrich Meckel the Elder. This is also called ganglion pterygopalatinum, nasal ganglion or sphenopalatin ganglion. It has three roots called sensory, motor and sympathetic roots.
The ganglion is a clinical term given to the matter of gray matter consisting of nerve cells that are located outside the central nervous system (CNS). This part of the nervous system is thus named because it combines information obtained from all parts of the body, thereby coordinating the function of the body. As the main part of the nervous system, the CNS contains its main components: brain and spinal cord.
Parasympathetic ganglie, category to which the pterygopalatin ganglion belongs is part of the peripheral nervous systemMU (PNS). This is the division of the nervous system in which ganglia is located, among other things, types of nerves. It is responsible for connecting the CNS with the organs and limbs for innervation. These parts of the body would lack stimulation without such an offer.
triangular or heart -like heart with red -gray pigmentation is named parasympathetic ganglion after its location, pterygopalatin fossa. It is a tears -shaped channel located on the side side of the skull, immediately behind the upper jaw or Maxilla. It serves as a primary place for supplying blood and innervation of upper jaws with maxillary artery and maxillary nerve.
As far as the pterygopalatin ganglion itself is concerned, it is directly below the maxillary nerve and is responsible for innervating specific head and neck sites. This includes the lachrymal glands that are in the eyes of mandels; Paranasal cavities that are air filled with spaces to placenot around the nasal cavity; and gingiva or gums. Also, ganglion pterygopalatin works with nerve nerve or sphenopalatin nerve, which innervates the front teeth of the maxillas.
Pterygopalatin ganglion is the largest of parasympathetic ganglia, others are ciliary ganglion, ear ganglion and submandibular ganglion. The ciliary ganglion is located behind orbit, which are cranial drawers that are placed and their pendants. The Ototic Ganglion is located in a hole on the base of the skull called the foramen ovale. The subandibular ganglion is named after its place of placement, which is the lower jaw or jaw. It is responsible for innervation of oral salivary glands called submandibular gland and sublingual gland.
