Explore the following hand diagrams to get a better understanding of the anatomy of the hand, especially the bones. To understand this body part, see below diagrams for both the bone-labeled diagrams! Each of these diagrams illustrates the bone parts with the labels. Click on the diagram to enlarge and save!
The skeleton of the human hand consists of 27 bones. the eight short carpal bones of the wrist are organized into a proximal row (scaphoid, lunate, triquetral and pisiform) which articulates with the bones of the forearm, and a distal row (trapezium, trapezoid, capitate, and hamate), which articulates with the bases of the five metacarpal bones of the hand. The heads of the metacarpals will each in turn articulate with the bases of the proximal phalanx of the fingers and thumb. See those parts in the following hand diagrams below and try to understand the different names of each part.
A reliable way of identifying human hands is from the presence of opposable thumbs. Opposable thumbs are identified by the ability to be brought opposite to the fingers, a muscle action known as opposition. There are also numerous sesamoid bones in the hand, small ossified nodes embedded in tendons; the exact number varies between people. Now the unlabeled one is provided below and you can try to label it.
From the diagrams above, you can learn many important parts of the hand anatomy. The unlabeled diagrams are purposed for evaluation and review.
