The term finger joint is commonly used to describe the articulation point of the fingers, where the bones of the hand connect. However, there are several other synonyms that could be used to describe this particular part of the hand. One such term is interphalangeal joint, which specifically refers to the joints found between the phalanges or finger bones. Metacarpophalangeal joint is another term used to describe the knuckles, where the hand bones meet the finger bones. In layman's terms, finger joint may also refer to the area where the fingers bend, which could be described as the flexor tendon sheath or flexor digitorum profundus tendons.
