Definition of ganglion in English: ganglionnounPlural ganglia, Plural ganglions ˈɡaŋɡlɪənˈɡæŋɡliən 1Anatomy A structure containing a number of nerve cell bodies, typically linked by synapses, and often forming a swelling on a nerve fibre. 〔剖〕神经中枢 Example sentencesExamples - Herpes zoster is caused by reactivation of varicella-zoster virus from a dorsal root ganglion to a cutaneous nerve and the adjacent skin.
- In the first form (restlessness and dysphagia), the lesions tend to concentrate in the brain stem and the cranial nerve ganglia.
- This nerve carries the otic ganglion, which is derived from glossopharyngeal neurons.
- The new regulation expands that prohibition to include dorsal root ganglia, clusters of nerve cells connected to the spinal cord along the vertebrae column.
- The two major plexuses consist of ganglia, clusters of nerve cell bodies disposed at more or less regular intervals over the surface of the cylinder.
- 1.1 A network of cells forming a nerve centre in the nervous system of an invertebrate.
(无脊椎动物神经系统中心的)神经细胞群 Example sentencesExamples - For some experiments, samples of gill, claw muscle, hepatopancreas, gonad, and thoracic ganglion were also removed to serve as controls.
- It appears as if all of the staining in the cerebral ganglia is due to processes emanating from cells in the ganglia at the base of the tentacles.
- If this experiment were possible I would predict that removing the rhopalial ganglion cells would eliminate a behavioral response to light even if the eyes and the swim system remained unharmed.
- Swim interneuron isolation was done according to methods previously described by them, by pulling the cell out of the ganglia using the recording microelectrode.
- The MIH transcript is detectable in eyestalk neural ganglia throughout the molt cycle of the blue crab, Callinectes sapidus.
- 1.2 A well-defined mass of grey matter within the central nervous system.
神经节。参见BASAL GANGLIA See also basal ganglia Example sentencesExamples - In normal circumstances, nerve cells in the part of the brain called the basal ganglia produce the chemical dopamine.
- Inflammation is commonly present in the basal ganglia, brainstem, spinal cord, and dorsal root ganglia and is composed of a perivascular lymphocytic infiltrate with accompanying glial reaction.
- Occurrence of neurodegeneration was indicated by the vacuolar appearance of neural tissues of the brain or ganglia.
- Parkinson's disease affects a part of the brain's motor system called the basal ganglia.
- It is deposited in those brain ganglia that normally house iron.
2Medicine An abnormal benign swelling on a tendon sheath. 〔医〕腱鞘囊肿 Example sentencesExamples - Flexor tendon sheath ganglia make up the remaining 10 to 15 percent.
- It is the breakdown of the synovial tissue of tendon sheaths that gives rise to most ganglia.
- The most commonly considered diagnoses are ganglion, implantation dermoid, cyst, abscess, lipoma, subcutaneous foreign body granuloma, and tendon sheath xanthoma.
- The differential diagnosis of a suture granuloma includes abscess, surgical wound inflammation, lipoma, neoplasm, or ganglion cyst.
- Metastatic lesions may be confused with a ganglion, epidermoid inclusion cyst, acute gout, and even rheumatoid arthritis.
OriginLate 17th century: from Greek ganglion 'tumour on or near sinews or tendons', used by Galen to denote the complex nerve centres.
