Pulso

Pulso
Pulso nunha man dereita humana
Latín	articulatio radiocarpea
Articulacións	articulación do pulso

Na anatomía humana, o pulso pode ser definido coma 1) o carpo, o complexo de oito ósos que forman o esqueleto da parte máis proximal da man;^[1][2] (2) a articulación do pulso ou articulación radiocarpal, a articulación entre o radio e o carpo;^[2] e (3) a rexión anatómica ao redor do carpo incluíndo as epífisis distais dos ósos do antebrazo (radio e cúbito) e a parte proximal do metacarpo ou cinco óso metacarpais e a serie de articulacións entre eles, tamén denominada articulación do pulso.^[3][4] Esta rexión tamén inclúe o arco do carpo, a entrada na man, para os músculos extensores e flexores da man.

Debido a esta variabilidade de definiciións, a fractura dun o varios ósos do carpo considérase unha rotura carpal, pero cando se lesionan outras estruturas coma as partes distais do cúbito ou radio, fálase de roturas do carpo. ^[5]

2. ↑ ^{2,0 2,1} Moore 2006, p 485. "The wrist (carpus), the proximal segment of the hand, is a complex of eight carpal bones. The carpus articulates proximally with the forearm at the wrist joint and distally with the five metacarpals. The joints formed by the carpus include the wrist (radiocarpal joint), intercarpal, carpometacarpal and intermetacarpal joints. Augmenting movement at the wrist joint, the rows of carpals glide on each other [...] "
3. ↑ Behnke 2006, p 77. "With the large number of bones composing the wrist (ulna, radius, eight carpas, and five metacarpals), it makes sense that there are many, many joints that make up the structure known as the wrist."
4. ↑ Baratz 1999, p 391. "The wrist joint is composed of not only the radiocarpal and distal radioulnar joints but also the intercarpal articulations."
