Ganglion Doral Wrist EDC large
Ganglions form in areas where synovium is present i.e.. joints or tendon sheaths. Synovium is a material that secretes synovial fluid to lubricate surfaces and prevent friction. In a joint it allows cartilage covering the ends of bones to glide over one another and for tendons it allows migration of the tendon within the tendon sheath and prevents friction with adjacent tendons.

Ganglion being excised. Ganglions are typically filled with thick gelatinous material and frequently are septated and is why they are difficult to completely aspirate.
