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 ...
Having a skeleton of phalanges, joined by hinge-like joints that provide flexion toward the palm of the hand. Having a dorsal surface that features hair and a nail, and a hairless palmar aspect with fingerprint ridges. The thumb contrasts with each of the other four fingers by being the only one that:
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 ...
These articulations with the fingers are the metacarpophalangeal joints known as the knuckles. At the palmar aspect of the first metacarpophalangeal joints are small, almost spherical bones called the sesamoid bones. The fourteen phalanges make up the fingers and thumb, and are numbered I-V (thumb to little finger) when the hand is viewed from ...
The carpometacarpal (CMC) joints are five joints in the wrist that articulate the distal row of carpal bones and the proximal bases of the five metacarpal bones.. The CMC joint of the thumb or the first CMC joint, also known as the trapeziometacarpal (TMC) joint, differs significantly from the other four CMC joints and is therefore described separately.
Joints of the hand, including the wrist and fingers. Joints of the foot, including the ankle and toes ... growths of bone called bone spurs can develop along the edges of the joint, leading to ...
Although each finger seems to move independently, moving one finger also moves the other fingers slightly which is called finger interdependence or finger enslaving. [14] [15] [16] Fingers do not contain muscles (other than arrector pili). The muscles that move the finger joints are in the palm and forearm. The long tendons that deliver motion ...
Metacarpophalangeal joint. The palmar aspect of the hand showing the epiphyses of the hand exploded. MCP joints in red. The metacarpophalangeal joints (MCP) are situated between the metacarpal bones and the proximal phalanges of the fingers. [1] These joints are of the condyloid kind, formed by the reception of the rounded heads of the ...
