Anatomy and Functional Anatomy of the Hand 1.1 Introduction In their biological taxonomy and status as “higher-level mammal—homo sapiens,” humans owe their distinction from primates to the miraculous structure of the hand. With its 19 degrees of freedom and its opposing thumb, the hand is a highly developed and complex grasping organ. The joint near the end of the finger is called the distal IP joint (DIP joint). The thumb only has one IP joint between the two thumb phalanges.

Joints of the Hand Anatomy The carpometacarpal, metacarpophalangeal and interphalangeal joints are synovial and allow the hand to perform its various func tions, including the intricate movements involved in gripping objects.

Other stabilizers in the hand include the joint capsules, which are also made up of fibrous connective tissue that surround each of the joints. Synovial membranes line the inner aspects of the joint capsules and produce synovial fluid to lubricate all the joints.

2016-04-14 · Detailed Anatomy of the Grip. Hand Positioning . As can be deduced from figure 1 the grip is characterised by the flexion of digits 2-5 and flexion and adduction of the thumb around the object but in opposing directions, i.e. if digits 2-5 wrap around the object anti-clockwise the 1 st digit (thumb) will wrap clockwise.

When these joints are injured or inflamed, doing detailed work with the fingers and fingertips becomes very difficult. Understanding hand anatomy and the way the joints in your fingers move can help you protect against injury.

Figure 4. Each individual digit or finger The proximal interphalangeal (PIP) joints of the fingers are extremely important for gripping things with hands, more specifically, what is called the 'power' grip. Wrist joint & joints of hand. • Synovial joint.

The joints most commonly affected by osteoarthritis are the wrist, finger joints and thumb base. Pain at the base of the thumb can result in difficulty gripping or

It consists of a main radiocarpal joint, between the radius and the proximal row of the carpal bones minus the pisiform, and the smaller intercarpal joints, which are small joints among the carpals. The functional classification of joints is determined by the amount of mobility found between the adjacent bones. Joints are thus functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, which is a freely moveable joint (arthroun = “to fasten by a joint”). The anatomy of the hand is incomplete without understanding the wrist. This complex structure connects the entire hand to the radius and ulna, facilitates the passage of tendons together with the above mentioned neurovascular structures from the forearm to the hand, and permits us to exploit anatomy.
