Fingerrelated

Fingerrelated refers to anything pertaining to fingers, the digits at the distal part of the hand. In anatomy, fingers consist of phalanges (proximal, middle, distal), connected to the hand via metacarpals and joints such as MCP, PIP, and DIP. The flexor and extensor tendon systems allow bending and straightening; nerves (median, ulnar, radial) provide motor control and sensation; fingerprints are unique dermal patterns.

In function, fingers enable grasp, precision manipulation, and tactile exploration. The thumb's opposition is a key feature of dexterity.

Health and pathology: common finger injuries include distal phalanx fractures, mallet finger (extensor damaged), jersey finger (flexor tendon avulsion), and trigger finger (stenosing tenosynovitis) causing catching of the tendon. Dupuytren's contracture is a fibrous thickening of the palmar fascia affecting finger extension. Treatment ranges from splinting and physiotherapy to surgical repair, depending on severity. Recurrent nail bed injuries and infections are also documented.

Technology and forensics: fingerprints provide biometric identification, with patterns such as loops, whorls, and arches used in security systems. Ergonomics and sports science study finger force, joint loads, and grip strength to enhance performance and reduce injury. Developmental and pediatric considerations emphasize sensorimotor skills and finger dexterity.

The term fingerrelated is used informally in discourse to denote topics connected to the fingers rather than a formal medical diagnosis or taxonomy.
