Synonyms Hand physiology ; Hand structure Definition The anatomy of human hand is quite unique and includes the configuration of bones, joints, veins, and muscles. The physiological interconnection and structure of these parts are responsible for the structure of the human hand. The functional area ...

Joint, in humans and other animals, structure connecting two or more adjacent parts of the skeleton. Not all joints move, but, among those that do, motions include spinning, swinging, gliding, rolling, and approximation. Learn about the different types o

In this concept the wrist joint functions with 3 parallel longitudinal chains. In each of these chains the proximal carpal functions as an intercalated bone. The specific shape of the intercalated bones establishes a simultaneous movement in the radiocarpal and the midcarpal joints which is a ...
kinematics of the wrist joint is presented and different biomechanical model approaches. The therapeutic (surgical) restoration of the balance between the load–bearing capacity and the actual stress on a joint is the prerequisite for a lifelong and trouble-free function of a joint. Regarding the ...
Let's begin with the basics of human body drawing. A well-proportioned figure, regardless of variations due to gender and such, is defined by the alignment of the joints, which is invariable (that is, we perceive something odd if it does vary). This is our groundwork for the proportions...
