A Structured Rehabilitation Protocol for Improved Multifunctional Prosthetic Control: A Case Study
Published on: November 6, 2015
Abstract:
A funtional morphological study has been made of the joints of the primate hand, particular emphasis being placed upon the carpometacarpal and metacarpophalangeal joints. The presumptive evolutionary history of these joints has been charted by reference to a comparative series of mammals. It has been demonstrated that the human joints have been quite strikingly modified in a number of ways, and that these evolutionary changes may be logically correlated with the refined functional attributes of the human hand. The morphological background thus established has been applied in a preliminary study of the hand bones of various fossil hominids.

Changes in the Appendicular Skeleton with Age
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
Development of the Limb Synovial Joints
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
During development, the limbs...

Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi radialis,...
