The hand itself is an amazing part of the human body. It allows a huge range of movements and positions all possible because of the bone structure, muscles and tendons that provide flexibility yet strength. The hand and fingers are extremely complex in their overall design. Using a 3D finger model is a great way help students understand the complexity of the hand and how the bones, tendons and muscles interact to allaow movement. In total there are 27 bones in the entire human hand from the wrist through to the end of the fingers. A 3D finger model will include all 27 and specifically the 14 digital bones, which are the bones of the fingers and the thumb. These fourteen bones are all identified as phalanges or finger bones and they work to create the grasping motion that helps us do things that other species without fingers cannot do. However, the very design of the phalanges also makes them prone to muscle and bone problems such as finger strains, sprains, tendonitis, factures and even amputation.

With all this detail a flat picture in a text book or a 3D finger model online isn't going to provide a comprehensive view for a student or for a patient. The biggest benefit to the 3D finger model is that it can be turned, positioned and rotated to allow the student to see exactly what they need to. This simply cannot be duplicated in a textbook or on an anatomical chart. Online 3D programs can provide the visual aspect similar to the model, which makes them a good second option. The actual physical model is the only option that allows manipulation and positioning to prove just the right vantage point for students to clearly see what is being discussed.

A 3D finger model that includes the wrist bones, tendons and some of the major muscle groups is a beneficial model to consider for a classroom environment. These larger models are perfect for students to develop a good understanding of how the entire hand moves. This can provide insight into diagnosis and treatment of finger, wrist and hand injuries. A full arm model can supplement the two above mentioned models in human anatomy classes and laboratory work. Always try to work with life-sized models for ease of identifying and working with even the smallest features of the fingers, hand and wrist. Many of the top quality 3D finger model styles will include easy to use background cards that show a diagram of the anatomy model and provide identification for the bones and features included. For students and instructors this is an ideal option for self-study and review since the card can be used for verification of answers or in assistance with identifying specific structures. Removing the card then allows the student to practice identifying the various bones, tendons and muscles displayed on the 3D finger model is a great review exercise that is much more engaging for the student than just working through a textbook or watching an online presentation.
