I remember learning once that each of the fingers served a different purpose. I don't recall if this was in Talmud or Shulchan Aruch. What do our sources say is the purpose behind each of the different fingers?

2Well, the thumb is to more easily hold things, the index finger is to point to things... I mean, what is it that you’re looking for? – DonielF Sep 12 '18 at 3:24
Zeret: The pinky finger. In Shemos 39:9 it is used as a measurement, which when doubled, serves as the length and width of the Kohen Gadol’s breastplate.
Kemitza: The ring finger. In the grabbing flour part of a kemitza offering, this was the finger it would start from, spanning to the ama and etzba fingers.
Ama: The middle finger. From the end of this finger to the elbow is the ama measurement for building and vessels.
Etzba: The pointer finger. Used to sprinkle blood of sacrifices on the alter.
Godel: The thumb finger. Used to purify a metzora with blood and oil.

Add the source discussing the fingers from the Talmud(Shabbat or Pesachim?) and it would be an even better answer. – chacham Nisan Sep 13 '18 at 8:36
