Thumb
[[File:Thumbup.jpg|thumb|right|Thumb.]]
The '''thumb''' is one of the five digitfingers on the human [[hand]]. Thumbs are different from the other four fingers because they are in a different [[direction]], have only two [[Phalanges|bones]] (the others have three) and are shorter. Thumbs help us to pick things up. This is called having "opposable thumbs". All [[primate]]<nowiki/>s have thumbs but humans have fully opposable thumbs.

Thumbs have an [[artery]] in them. Arteries have a [[pulse]]. This is why we should not take other peoples' pulses with our thumbs.
