Which term represents the true index finger, the second digit?

• A. Mammillary Process (MP)
• B. Index finger (IF)
• C. Transverse process (TVP)
• D. Chiropractic Index Finger (CIF)

Answer: (B)

In human hand anatomy, digits are numbered from I to V, with the thumb being the first digit and the index finger being the second. The standard term for that finger is “index finger,” which is the common and anatomically correct name for the second digit. The other terms refer to parts of the spine (mammillary process and transverse process) or an unconventional label that isn’t used in standard anatomy, so they don’t describe the finger. Therefore, the true index finger is the index finger.
