The little finger or pinkie, also called the baby finger or pinky finger, is the smallest finger of the human hand.
Etymology
[change | change source]The word "pinkie" comes from the Dutch word pink, meaning "little finger".
The earliest known use of the word "pinkie" is from Scotland in 1808.[1] The word (sometimes written "pinky") is common in Scottish English[2] and American English,[3] and is also used a lot in other Commonwealth countries such as New Zealand, Canada, and Australia.[4][5]
Nerves and muscles
[change | change source]There are nine muscles that control the little finger: Three in the hypothenar eminence, two extrinsic (outside the hand) flexors, two extrinsic extensors, and two more intrinsic (inside the hand) muscles:
- 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)
- Two extrinsic flexors:
- Two extrinsic extensors:
- Two intrinsic hand muscles:
- Fourth lumbrical muscle
- Third palmar interosseous muscle
Note: the dorsal interossei of the hand muscles are not attached to the little finger
