Por qué el cuerpo humano tiene entre 206 y 208 huesos? Como están compuestos los Miembros inferiores? (Aclarar sus partes).
Darya [45]

Answer:

El cuerpo humano posee 206 huesos (208 huesos teniendo en cuenta huesecillos del oído medio)

Miembros inferiores > fémur, tibia, peroné, tarso, metatarso y falanges.

Explanation:

En adulto se compone de 206 huesos, pero algunos autores sostienen que el cuerpo humano está compuesto por 208 huesos debido a que el hueso del estribo (estapedio) perteneciente a la cadena de huesecillos del oído medio se suele considerar como dos unidades independientes (lenticular y estribo), dando así lugar a un total de 208 huesos. Por otra parte, otros autores también han considerado la posibilidad de que el cuerpo humano está compuesto por 208 huesos debido a variaciones en el número de las vértebras. Los huesos de miembros inferiores se dividen de acuerdo a su localización en huesos del muslo, de la pierna y del pie. El muslo contiene un sólo hueso conocido como fémur (el hueso más largo del cuerpo). La pierna posee dos huesos llamados tibia y peroné los cuales se disponen paralelamente. La tibia es más larga y gruesa que el peroné debido a que la tibia soporta todo el peso de la articulación. Finalmente, el pie se compone del tarso, el metatarso y las falanges (huesos de los dedos). El tarso posee siete huesos (calcáneo, astrágalo, navicular, cuboides y tres cuñas), mientras que el metatarso posee cinco huesos (primero, segundo, tercero, cuarto y quinto). Al igual que en los miembros superiores, el dedo gordo del pie posee dos falanges conocidas como proximal y distal, mientras que los cuatro dedos restantes poseen tres falanges (proximal, media y distal).
