The cysts may intrude into the spine, which may cause pain and dysesthesia in distant extremities. [ 20 ] Cystic adventitial disease , in which a cyst occurs within the popliteal artery near the knee, has been proposed recently to occur by an articular mechanism, with a conduit leading from the joint, similar to the development of ganglion ...
Hypermobility, also known as double-jointedness, describes joints that stretch farther than normal. [2] For example, some hypermobile people can bend their thumbs backwards to their wrists and bend their knee joints backwards, put their leg behind the head or perform other contortionist "tricks".
The indications for ganglion impar blockade are based on the anatomical location of pain and include various conditions such as perineal pain (with or without malignancy), rectal/anal pain (proctitis), distal urethral pain, vulvodynia, scrotal pain, female pelvic/vaginal pain (distal 1/3), sympathetically-maintained pain (e.g., Complex Regional ...
The geniculate ganglion may become inflamed due herpes zoster virus virus infection. Swelling of the ganglion may result in facial palsy (Ramsay Hunt syndrome).The syndrome presents with intense pain in one ear that is followed by a vesicular rash around the ear canal.
There are usually 22–23 pairs of these ganglia: three cervical ganglia, 12 thoracic ganglia (the stellate ganglion (cervicothoracic) is formed from the fusion of the first thoracic ganglion with the inferior cervical ganglion), four lumbar ganglia, and four or five sacral ganglia. In the area of the coccyx there is a small ganglion impar. The ...
The dorsal root ganglion contains cell bodies for sensory nerves including large, myelinated Aβ fibers which carry proprioception and tactile touch sensation to the brain via the dorsal column–medial lemniscus pathway and small, unmyelinated C fibers which carry thermal and pain sensation to the brain via the spinothalamic tract.

Constipation or diarrhea, emesis, anorexia, early satiety, and abdominal pain are common symptoms of gastrointestinal dysmotility, which affects 70% of patients. [ 1 ] Although about a quarter of patients report neuropathic symptoms such as tingling in the distal extremities, sensory examination and nerve conduction studies are normal.
The term "ganglion" refers to the peripheral nervous system. [ 1 ] However, in the brain (part of the central nervous system ), the basal ganglia are a group of nuclei interconnected with the cerebral cortex , thalamus , and brainstem , associated with a variety of functions: motor control, cognition, emotions, and learning.
