Trigeminal ganglion

Trigeminal ganglion (Latin g. trigeminale, English trigeminal ganglion) - also known as the semilunar ganglion or gasserian ganglion. This is a sensory ganglion of the trigeminal nerve located in the cranial cavity.

The trigeminal ganglion contains pseudounipolar neurons, the central processes of which form the sensory roots of the trigeminal nerve, and the peripheral processes innervate the areas of the face and oral cavity. The ganglion is located in the recess of the petrous part of the temporal bone - the cavity of the trigeminal nerve. Three branches of the trigeminal nerve arise from the ganglion: the orbital, maxillary and mandibular.

The trigeminal ganglion plays an important role in conducting sensory impulses from facial receptors to the central nervous system. Damage to the ganglion can lead to sensory disturbances in the area of ​​innervation of the trigeminal nerve.

Triangular nerve ganglion

The triangular ganglion is part of the nervous system system that is responsible for the body's perception and response to external stimuli. In this article we will look at the triangular ganglion and its functions and connections to other parts of the nervous system.

**The triangular ganglion** is a small ganglion that is located behind the frontal part of the head. It is connected to the trigeminal nerve, which is one of the 12 cranial nerves. The trigeminal nerve consists of three branches, each of which is connected to its own area of ​​the face: - The first branch is connected to the eye and is responsible for the motor activity of the pupil and eye muscles. - The second branch is associated with the mouth and tongue and controls sucking, chewing and tongue movement. - The third branch is connected to the upper part of the face and is responsible for the ability to hold the head and control the movement of the facial muscles. The trigeminal ganglion provides communication between the trigeminal nerves and the muscular systems. It is located at the front of the ear and is connected to the outer ear through the Eustachian tube (the bone that connects the middle ear to the nasal cavity). When the ganglion of the triangular nerve doubles, it becomes Harmon's ganglion. **Han's triangle** is the overall structure of the head, including the brain, eyes, ears, nose and other organs. It is important to note that the trigeminal ganglion is connected not only to the trigeminal nerve, but also to the six cranial nerves that connect the head to the brain and spinal cord (it is also connected to some peripheral ganglia, such as the submandibular ganglion).

This collection of nerves connects the head and body, using one or more nerves responsible for communication between the center of the brain and the periphery of the body. Hansemonium triangle is the main node of the brain, responsible for communication through many channels simultaneously.
