Thumb. The thumb digit has only two phalanges (bones) so it only has one joint. … The terminal extensor tendon in the thumb comes from the extensor pollicis longus muscle. The radial and ulnar collateral ligaments are important to provide stability of the fingertip during pinching.
I agree that 20 digits is correct. We could say, “The typical human has ten fingers and toes.” You could refer to toes as fingers as a metaphor if you were describing someone with uncommon dexterity in their toes.

The little finger, often called the pinky in American English and pinkie in Scottish English (from the Dutch word pink, meaning little finger), is the most ulnar and usually smallest finger of the human hand, opposite the thumb, next to the ring finger.
Ask an evolutionary biologist, however, and you’re likely to get a much simpler answer: We have 10 fingers and 10 toes because, somewhere in our species’ past Darwinian wanderings, those numbers gave us an evolutionary advantage. Had events tumbled differently, we might have eight fingers and twelve toes.
So why do we have pinky toes? The answer goes back to the evolutionary history of humans, explains Dr. Anish Kadakia, assistant professor in orthopaedic surgery at Northwestern University. “Primates use their feet to grab, claw, to climb trees, but humans, we don’t need that function anymore,” Kadakia says.

Toes are the digits of the foot. The toe refers to part of the human foot, with five toes present on each human foot. Each toe consists of three phalanx bones, the proximal, middle, and distal, with the exception of the big toe (Latin: Hallux).
Many groups have lost digits, but five is still the basic number. A horse has a single toe on each foot but if you look at an early horse embryo, its limb buds have five little stripes of Sox9, just like ours. Some might say that we never need more than five fingers, but that’s not true either.
For most people the strongest finger is the middle, then ring, index, and followed with pinky.
