The trigeminal ganglion (also known as: Gasserian ganglion, semilunar ganglion, or Gasser's ganglion) is the sensory ganglion of each trigeminal nerve (CN V). The trigeminal ganglion is located within the trigeminal cave (Meckel's cave), a cavity formed by dura mater.

The trigeminal ganglion is a neural crest derived ganglion that contains the sensory neurons of the trigeminal nerve. It can be thought of as equivalent to the dorsal root ganglia of the spinal nerves (O'Rahilly & Müller, 2007).

The trigeminal ganglion consists of clusters of sensory neurons and their peripheral and central axon processes, which are arranged according to the three trigeminal partitions V1–V3. The neurons are surrounded by satellite glial cells, the axons by Schwann cells.

2024年7月22日 · What is the trigeminal nerve? Your trigeminal nerve, also known as cranial nerve 5 or CN V, is a large, three-part nerve in your head that sends signals from your brain to parts of your face, and vice versa. You have two trigeminal nerves — one on each side of your face. They’re one set of 12 cranial nerve pairs.

The trigeminal ganglion is a thin crescent-shaped (semilunar) structure (5, 6) that lies at the anterior, inferior, and lateral aspects of the Meckel cave (6, 10, 21). The convex surface of the ganglion is directed toward the anteroinferolateral walls of the Meckel cave .

2023年3月20日 · Trigeminal neuralgia, when refractory to medical treatment, can be effectively treated by percutaneous interventions at the semilunar ganglion by accessing the foramen ovale through the oral cavity and ablating the ganglion by radiofrequency, balloon compression, or chemical means.

2023年4月14日 · The trigeminal ganglion, also known as the Gasser, Gasserian or semilunar ganglion, is the large crescent-shaped sensory ganglion of the trigeminal nerve located in the trigeminal cave (Meckel cave) surrounded by cerebrospinal fluid.

2024年10月31日 · The trigeminal ganglion is located on the inside of the skull in front of your ear near your temple. The motor nerve branch of the trigeminal nerve is smaller than the sensory branches and exits from the brainstem through the root of the trigeminal nerve.

The trigeminal ganglion (TG), a cluster of pseudounipolar neurons, is located in the trigeminal impression of the temporal pyramid. It is covered by a sheath of the dura mater and arachnoid and is near the rear end of the cavernous sinus.

2025年1月17日 · The trigeminal ganglion, also known as the semilunar ganglion or the Gasserian ganglion, is a collection of sensory neurons located in the head that is responsible for transmitting sensory information from the face and mouth to the brain.
