Cov hauv caug ntog sub uniaxial raws li nws yog pob khawm sib koom thiab nws txav mus hauv ib lub dav hlau nrog kev txav me ntsis, tab sis kev sib hloov tsis txaus yuav suav tias yog qhov tseem ceeb.
Ib yam nkaus, tib neeg nug, puas yog qhov sib koom ua ke tsis sib xws?

Condyloid pob qij txha tau pom ntawm lub hauv paus ntawm cov ntiv tes (metacarpophalangeal pob qij txha ) thiab ntawm lub dab teg (radiocarpal sib koom ).
Ib tus kuj yuav nug, lub hauv caug puas yog pob khawm sib koom?
