The interphalangeal joints of the hand are the hinge joints between the phalanges of the fingers that provide flexion towards the palm of the hand . There are two sets in each finger (except in the thumb, which has only one joint): Anatomically, the proximal and distal interphalangeal joints are very similar. There are some minor differences in ...

Oct 30, 2023 · The interphalangeal joints of the hand are synovial hinge joints that span between the proximal, middle, and distal phalanges of the hand. In digits 2-5 these joints can be further classified based on which bones are involved. The proximal interphalangeal joint (PIPJ or PIJ) is located between the proximal and middle phalanges, while the distal ...

The joints in the hand are joints found at the distal end of the upper limb. The joints are: In the wrist there is the radiocarpal joint between the radius and carpus. Between the carpal bones are the intercarpal articulations and the midcarpal joint. The carpometacarpal joint connects the carpal bones to the metacarpus or metacarpal bones ...

Function. The DIP, PIP and MCP joints of the hand: - D istal I nter P halangeal - P roximal I nter P halangeal - M eta C arpo P halangeal. The function of the interphalangeal joints of the hand to permit fine motor movements in the digits. To accomplish this, these joints facilitate movement within only one degree of freedom: flexion - extension.
The final ligaments of the interphalangeal joints are the collateral interphalangeal ligaments of the hand. These ligaments can be found on either side of each interphalangeal joint arising from the head of the more proximal phalanx and extending to the palmar aspect of its distal counterpart.
<p>The human hand is made up of the wrist, palm, and fingers and consists of 27 bones, 27 joints, 34 muscles, over 100 ligaments and tendons, and many blood vessels and nerves.</p> <p>The wrist is comprised of 8 carpal bones. These wrist bones are attached to the radius and ulna of the forearm to form the wrist joint. They connect to 5 metacarpal bones that form the palm of the hand. Each ...
