127. Lower extremity of the bones of the right 



forearm, from below. 



The lower extremity of the bones of the forearm (see also Fig. 

 which forms the articulation with the carpus, presents on its distal surface the fades 

 articularis carpea radii and the capitulum ulnae. The former articulates directly 

 with the os naviculare manus and the radial part of the os lunatum. The capitulum 

 ulnae on the contrary does not touch the ulnar part of the os lunatum and the os 

 triquetrum, situated distalward from it, directly, but is separated from them by a discus 

 articularis. 



On the sides of this surface the two processus styloidei are visible.
