Little finger

The little finger, often called the pinky in American English, pinkie in Scottish English (from the Dutch word pink, and ultimately deriving from Proto-Indo-European *pénkʷe, "five", "finger"), or small finger in medicine, is the most ulnar and usually smallest finger of the human hand, opposite the thumb, next to the ring finger.

Muscles

There are four muscles that control the little finger: Three intrinsic muscles comprising a group called the hypothenar eminence, and one extrinsic, the extensor digiti minimi:

• hypothenar eminence
  • Opponens digiti minimi muscle
  • Abductor minimi digiti muscle (adduction from third palmar interossei)
  • Flexor digiti minimi brevis (the "longus" is absent in most humans)
• Extensor digiti minimi muscle
• Fourth lumbrical muscle
